Which Brain Part Controls Digestion

Chicago IL Digestion Solutions: How The Brain Controls The Digestive System


The autonomic nervous system controls the tone of the digestive tract. The brain controls drinking and feeding behavior. The brain controls muscles for eating and elimination. The digestive system sends sensory information to the brain.

Subsequently, question is, what part of the brain is responsible for movement? The cerebellum is at the back of the brain, below the cerebrum. It’s a lot smaller than the cerebrum. But it’s a very important part of the brain. It controls balance, movement, and coordination .

Also asked, what nervous system controls digestion?

Control of the digestive system is also maintained by enteric nervous system , which can be thought of as a digestive brain that helps to regulate motility, secretion, and growth. The enteric nervous system can act as a fast, internal response to digestive stimuli.

What part of the brain regulates metabolism?

The pituitary gland also uses hormones to control how much sugar and water is in your body. It also is one of the areas that controls the body’s metabolism. It helps control the digestion of food, breathing, and moving your blood around.

The Cerebellum And Prefrontal Cortex

; ;The cerebellum plays a large role in implicit memories . For example, an individual with damage to their hippocampus will still demonstrate a conditioning response to blink when they are given a series of puffs of air to their eyes. However, when researchers damaged the cerebellums of rabbits, they discovered that the rabbits were not able to learn the conditioned eye-blink response . This experiment demonstrates the important role the cerebellum plays in the formation of implicit memories and conditioned responses.

Recent estimates of counts of neurons in various brain regions suggests there are about 21 to 26 billion neurons in the human cerebral cortex , and 101 billion neurons in the cerebellum , yet the cerebellum makes up roughly only 10% of the brain . The cerebellum is composed of a variety of different regions that receive projections from different parts of the brain and spinal cord, and project mainly to motor related brain systems in the frontal and parietal lobes.

In addition to contributions to implicit memory, conditioned responses, fine motor movements, posture and coordination, the cerebellum also maintains internal representations of the external world, which allow you to navigate through your living room to find your keys in complete darkness, and professional baseball players to coordinate their movement so they can catch outfield fly balls.

Examples Of Parasympathetic Responses

An easy acronym to remember how and where the PSNS works is SLUDD. This stands for:

  • Salivation: As part of its rest-and-digest function, the PSNS stimulates production of saliva, which contains enzymes to help your food digest.
  • Lacrimation: Lacrimation is a fancy word for making tears. Tears keep your eyes lubricated, preserving their delicate tissues.
  • Urination: The PSNS contracts the bladder, which squeezes it so urine can come out.
  • Digestion: The PSNS stimulates the release of saliva to promote digestion. It also enacts peristalsis, or the movement of the stomach and intestines, to digest food as well as release bile for the body to digest fats.
  • Defecation: The PSNS constricts the sphincters in the intestine and moves digested food material down the digestive tract so a person can have a bowel movement.

Keeping these things in mind, you can see why doctors may also call the parasympathetic system the feed and breed system.

Contextual Influences On Eating Behavior11

Laurette Dubé considered the different levels of context within whichbrain-digestive system interactions operate. Specifically, she consideredhow higher-level brain systems and mental processes ; the fetal environment and lifelongprogramming; parenting and other familial influences; and the broadersocial, commercial, and cultural food environment can impact eatingbehavior.

Which Controls Involuntary Actions In The Body

BioKnowledgy A.2 The human brain

The autonomic nervous system regulates involuntary and unconscious actions, such as internal-organ function, breathing, digestion, and heartbeat. This system consists of two complementary parts: the sympathetic and parasympathetic systems. It reduces bodily arousal, slowing the heartbeat and breathing rate.

The Brain Is The Boss

When youre taking a big math test, you know that your brain is hard at work. But your brain is doing a lot more than just remembering formulas. Those sweaty palms you get as the test starts? Thats your brain at work. The relief you feel when you know an answers right? Thats your brain too. And yes, your brain is even in charge when you take a minute to daydream about the big party on Friday night.

The brain may simply be the bossiest part of the body: It tells virtually every other part of your body what to do, all the time, whether youre aware of it or not. It controls what you think and feel, how you learn and remember, and the way you move. It also controls things you might not think about like the beating of your heart and whether you feel sleepy or awake.

How The Brain Works

Considering everything it does, the human brain is incredibly compact, weighing just 3 pounds. Its many folds and grooves, though, provide it with the additional surface area necessary for storing all of the bodys important information.

The spinal cord, on the other hand, is a long bundle of nerve tissue about 18 inches long and ¾ inch thick. It extends from the lower part of the brain down through spine. Along the way, various nerves branch out to the entire body. These make up the peripheral nervous system.

Both the brain and the spinal cord are protected by bone: the brain by the bones of the skull, and the spinal cord by the set of ring-shaped bones called vertebrae that make up the spine. Theyre both cushioned by layers of membranes called meninges as well as a special fluid called cerebrospinal fluid. This fluid helps protect the nerve tissue, keep it healthy, and remove waste products.

The brain is made up of three main sections: the forebrain, the midbrain, and the hindbrain.

3 Simple Brain Training Tips to Improve Your Digestion!

This crosstalk in communication between the brain and digestive system is opening up new ways to think about diseases. Not only do the gut and the brain communicate through the nervous system, but also through hormones, and the immune system. Microorganisms in the gut help regulate the bodys immune response. Medical researchers who are studying depressive symptoms, Parkinsons and Alzheimers disease, autism, amyotrophic lateral sclerosis, multiple sclerosis, pain, anxiety and other neuro conditions are beginning to look at what is going on in a person’s guts. Researchers who are investigating ulcers, constipation and other GI conditions also now have a reason to focus on aspects of brain functioning.

What Part Of The Brain Controls Digestion


The autonomic nervous system controls the tone of the digestive tract. The brain controls drinking and feeding behavior. The brain controls muscles for eating and elimination. The digestive system sends sensory information to the brain.

One may also ask, what controls the movement of your stomach? The pyloric sphincter controls the passage of partially digested food from the stomach into the duodenum where peristalsis takes over to move this through the rest of the intestines.

Also Know, is the brain part of the digestive system?

People are most familiar with the body’s central nervous system, which is made up of the brain and spinal cord. The enteric nervous system’s network of nerves, neurons, and neurotransmitters extends along the entire digestive tract from the esophagus, through the stomach and intestines, and down to the anus.

What part of the brain controls memory?

The main parts of the brain involved with memory are the amygdala, the hippocampus, the cerebellum, and the prefrontal cortex . The amygdala is involved in fear and fear memories. The hippocampus is associated with declarative and episodic memory as well as recognition memory.

Impact Of The Fetal Environment On Eating Behavior

Dubé characterized the fetal environment as a key context inbiology and behavior. She pointed to the Barker hypothesis as anexample. hypothesized that low birth weight is associated with increased risk ofmetabolic syndrome, diabetes, and obesity later in life. Dubépointed workshop participants to a forthcoming review in theAnnals of the New York Academy of Sciences onintrauterine growth restriction and its impact later in life.

In fact, researchers are finding correlations between IUGR and eatingbehavior not just later in life but early on as well. A study of24-year-old women who had been observed over their lifetime showed thatlow-birth-weight women were consuming more carbohydrates and had higherBMIs . Meanwhile, a study of 27-week-old preterm newbornbabies showed that low-birth-weight babies reacted less to sensitivitytests, postulated as being due to increased need, compared withnon-low-birth-weight babies of the same gestational age .Numerous other studies have found similar correlations across a widerange of ages .

What Are Some Examples Of How The Network Of Neurons In Our Gut And Brain Communicate With Each Other

There are several familiar examples. When a person feels danger, the fight or flight response of the central nervous system is triggered. At the same time, the enteric nervous systems response is to slow down or stop digestion. This is done so that more of the bodys energy can be diverted to the situation causing the threat.

The fear of public speaking also causes the digestive system to either slow down or speed up depending on the GI disorder and can cause abdominal pain, diarrhea, and other symptoms. Emotions, feelings of excitement, or nervousness can cause the familiar churning in the stomach the so-called butterflies in your stomach feeling. The gut-brain connection works in both directions too. For example, GI problems can create anxiety and stress.

New Gut Understanding Equals New Treatment Opportunities

This new understanding of the ENS-CNS connection helps explain the effectiveness of IBS and bowel-disorder treatments such as antidepressants and mind-body therapies like cognitive behavioral therapy and medical hypnotherapy. Our two brains talk to each other, so therapies that help one may help the other, Pasricha says. In a way, gastroenterologists are like counselors looking for ways to soothe the second brain.

Gastroenterologists may prescribe certain antidepressants for IBS, for examplenot because they think the problem is all in a patients head, but because these medications calm symptoms in some cases by acting on nerve cells in the gut, Pasricha explains. Psychological interventions like CBT may also help to improve communications between the big brain and the brain in our gut, he says.

Impact Of The Parental/familial/home Environment On Eatingbehavior

In the same cohort of 616 children aged 6 to 12 years discussed above,Dubé and colleagues also measured attachment .Attachment is an extensively studied construct in both animals andhumans, Dubé explained, with a measure of attachment providinginformation about the role of the primary caregiver in defining how ananimal or person decides to explore beyond what has been programmed atbirth. More secure attachment allows child and adult alike to engagewith confidence in novel activities, including exploring alternatives tobiological programming such as an innate liking for sugar and dislike of bitter foods . Using 24-hourrecall not just for food but also for other healthy and unhealthyeating-related habits, Dubé and colleagues found that childrenwith insecure attachment experienced high eating schematicity for allthree DEBQ eating behaviors; greater consumption of salty snacks; lowerconsumption of water and fruit; and greater likelihood of skippingbreakfast, eating out, and eating in front of the television duringweekdays. In Dubé’s opinion, these findings suggest thatmore attention should be paid, in both research and practice, toexploring how the early home environment influences a life course ofeating behavior.

Function Of The Autonomic Nervous System

The autonomic nervous system controls internal body processes such as the following:

  • Blood pressure

  • Digestion

  • Metabolism

  • The production of body fluids

  • Urination

  • Defecation

  • Sexual response

Many organs are controlled primarily by either the sympathetic or the parasympathetic division. Sometimes the two divisions have opposite effects on the same organ. For example, the sympathetic division increases blood pressure, and the parasympathetic division decreases it. Overall, the two divisions work together to ensure that the body responds appropriately to different situations.

Function Of The Medulla Oblongata

The digestive system – The “abdominal brain”

The medulla oblongata controls autonomic functions and connects the higher levels of the brain to the spinal cord. It is also responsible for regulating several basic functions of the autonomic nervous system, including:

  • Respiration: chemoreceptors
  • Reflex centers of vomiting, coughing, sneezing, and swallowing

The Brain & Nervous System In Everyday Life

If the brain is like a central computer that controls all the functions of your body, then the nervous system is like a network that sends messages back and forth from the brain to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back and contains threadlike nerves that branch out to every organ and body part.

When a message comes into the brain from anywhere in the body, the brain tells the body how to react. For example, if you accidentally touch a hot stove, the nerves in your skin shoot a message of pain to your brain. The brain then sends a message back telling the muscles in your hand to pull away. Luckily, this neurological relay race takes a lot less time than it just took to read about it!

Interaction Between The Brain And Digestive System

The workshop began with an exploration of what happens in the body when food is first consumed, that is, how the presence of food in the gut triggers signals to the brain about nutrient content, character, and volume and how that information, in turn, impacts further food intake. Timothy Moran of Johns Hopkins University explained how most of the information that the brain receives about gastrointestinal contents comes from vagal afferent feedback signals,1 some of which come from the stomach and others from the intestine. Most vagal signals sent from the stomach respond to factors such as stretch and tension and are related to the volume of food, not its nutrient content. Signals from the intestine, on the other hand, respond to both load and content, with the presence of nutrients in the intestine triggering the release of gut peptides, such as cholecystokinin , which, in turn, activate vagal afferent activity. Importantly, Moran said, while vagal signals from the stomach are different than those arising in the intestine, the two intersect in the hindbrain where, together, they play a role in reducing further food intake.

Components Of The Brainstem

The three components of the brainstem are the medulla oblongata, midbrain, and pons.

Brainstem Anatomy: Structures of the brainstem are depicted on these diagrams, including the midbrain, pons, medulla, basilar artery, and vertebral arteries.

The medulla oblongata; is the lower half of the brainstem continuous with the spinal cord. Its upper part is continuous with the pons. The medulla contains the cardiac, respiratory, vomiting, and vasomotor centers regulating heart rate, breathing, and blood pressure.

The midbrain is associated with vision, hearing, motor control, sleep and wake cycles, alertness, and temperature regulation.

The pons lies between the medulla oblongata and the midbrain. It contains tracts that carry signals from the cerebrum to the medulla and to the cerebellum. It also has tracts that carry sensory signals to the thalamus.

Basic Anatomy Of The Vagus Nerve


The vagus nerve carries an extensive range of signals from digestive system and organs to the brain and vice versa. It is the tenth cranial nerve, extending from its origin in the brainstem through the neck and the thorax down to the abdomen. Because of its long path through the human body, it has also been described as the wanderer nerve .

Figure 1. Overview over the basic anatomy and functions of the vagus nerve.

The vagus nerve is responsible for the regulation of internal organ functions, such as digestion, heart rate, and respiratory rate, as well as vasomotor activity, and certain reflex actions, such as coughing, sneezing, swallowing, and vomiting . Its activation leads to the release of acetylcholine at the synaptic junction with secreting cells, intrinsic nervous fibers, and smooth muscles . ACh binds to nicotinic and muscarinic receptors and stimulates muscle contractions in the parasympathetic nervous system.

Animal studies have demonstrated a remarkable regeneration capacity of the vagus nerve. For example, subdiaphragmatic vagotomy induced transient withdrawal and restoration of central vagal afferents as well as synaptic plasticity in the NTS . Further, the regeneration of vagal afferents in rats can be reached 18 weeks after subdiaphragmatic vagotomy , even though the efferent reinnervation of the gastrointestinal tract is not restored even after 45 weeks .
