The Heart As A Hormonal Gland

How Your Heart Actually Controls Your Emotions

In addition to its extensive neurological interactions, the heart also communicates with the brain and body biochemically by way of the hormones it produces. Although not typically thought of as an endocrine gland, the heart actually manufactures and secretes a number of hormones and neurotransmitters that have a wide-ranging impact on the body as a whole.

The heart was reclassified as part of the hormonal system in 1983, when a new hormone produced and secreted by the atria of the heart was discovered. This hormone has been called by several different names atrial natriuretic factor , atrial natriuretic peptide and atrial peptide. Nicknamed the balance hormone, it plays an important role in fluid and electrolyte balance and helps regulate the blood vessels, kidneys, adrenal glands and many regulatory centers in the brain. Increased atrial peptide inhibits the release of stress hormones, reduces sympathetic outflow and appears to interact with the immune system. Even more intriguing, experiments suggest atrial peptide can influence motivation and behavior.


Can You Recover From A Brain Stem Injury

Damage to some parts of the brain can be managed, however, brain stem injuries can be very difficult to and fatal to your overall health. It can even potentially cause permanent damage.

Thats because the brain stem connects your brain to all other parts of your body. Without a brain stem, that connection would be lost and your body cant function.

Injuries to the brain stem can affect your personality and even paralyze you. Since this is a very sensitive part of the brain, today treatment is limited and very expensive.

Its not about mental intelligence, its about mental fitness.

Brain stem treatment

Its not all bad news when it comes to treating brain stem injuries. As long as the injury is diagnosed early enough, it can be in many cases highly treatable.

Depending on the nature of the injury of course, and what areas of the body are affected, specific exercises and therapy can help strengthen the brain stems function.

Like any other muscle in your body, your brain including the brain stem grows and develops with regular exercise. This includes both actual physical exercise and brain workouts. Together, they stimulate the generation of new neurons and help keep your brain young and active.

The Cerebellum’s Balancing Act

Next up is the cerebellum. 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 .

Because of your cerebellum, you can stand upright, keep your balance, and move around. Think about a surfer riding the waves on his board. What does he need most to stay balanced? The best surfboard? The coolest wetsuit? Nope he needs his cerebellum!

Why Is The Brain Stem Important

Lesson 5 control of heart rate in humans me

Many experts believe that the brain stem is the most important part of the brain. To put it simply, the brain stem acts as a connection cable allowing connected nerves to send signals from your brain to the rest of your body.

Similarly to the tree trunk example we gave in our intro, the brain stem is basically the vital connection that keeps everything in functioning order. Without it, your brain cant communicate and send signals to the rest of the body and vice versa.

The Heart Also Affects Your Mind

In a final test in the film, Malone looks at images, some neutral and some frightened. Some are synced in time to his heartbeat, and others are not. The results revealed that when he saw the frightened images in sync with his heartbeat he perceived them as being more intensely frightened than when he saw them out of sync.

This would suggest that his heartbeat is affecting his mind, and processed a greater reaction in connection with the images and the heartbeat. During the test, researchers mapped the exact area of the brain that was affected by the heart, which was the amygdala.

The amygdala is known as the fight or flight brain structure and processes fear reactions, alongside signals from the heart. In this experiment, however, it is the human heart that is affecting the brain in the first instance.

Malone argues that:

It is our heart working in tandem with our brain that allows us to feel for others It is ultimately what makes us human Compassion is the hearts gift to the rational mind.

Each Part Of The Brain Controls What

The brain is a remarkable organ and incredibly complex. The three main regions of the brain are the midbrain, hindbrain and forebrain, which is broken up into additional sections including the frontal lobe, occipital lobe and temporal lobe that control different parts of the body. All of these work together like a well-oiled machine to allow humans to function properly.

The cerebellum is located at the lower back part of the brain. This part of the brain controls equilibrium and balance and allows humans to move correctly. It coordinates the muscles and joins so they can work together.

The occipital lobe controls vision. It is located at the very back part of the brain and affects how humans judge everything visual, from how something moves to how colors register. Two signs that something is wrong in this area of the brain are if the person experiences hallucinations or perceives colors differently.

A part of the brain called the temporal lobe controls a very important part of a person: memories. In addition, this specific part of the brain controls language functions, sexual functions and personality. It also has an effect on how the person perceives verbal and non-verbal input.

High Pressure High Risk

High blood pressure is the leading cause of strokes, both symptomatic and silent. Both systolic and diastolic hypertension contribute to risk the higher your pressure, the higher your risk. According to one Harvard study, hypertension increases a man’s risk of stroke by 220% according to another, each 10 mm Hg rise in systolic pressure boosts the risk of ischemic stroke by 28% and of hemorrhagic stroke by 38%.

That’s the bad news. The good news is that treating hypertension is extremely protective in round figures, if you reduce your systolic blood pressure by 10 mm Hg, you should cut your risk of stroke by a whopping 44%.

Can You Recover From A Brainstem Injury

“DO NOT LET YOUR MIND CONTROL YOUR HEART” – Moses Naidu, 21 March 2021

A brainstem injury can have severe effects because the brainstem controls so many of your bodys most basic functions. But people do recover from some types of brainstem injuries.

Its important to get care right away if you suspect a brainstem injury. The sooner you get care, the more likely your healthcare providers can reduce the damage. You may need rehabilitation and other special care after a brainstem injury.

The Cell Structure Of The Brain

The brain is made up of two types of cells: neurons and glial cells, also known as neuroglia or glia. The neuron is responsible for sending and receiving nerve impulses or signals. Glial cells are non-neuronal cells that provide support and nutrition, maintain homeostasis, form myelin and facilitate signal transmission in the nervous system. In the human brain, glial cells outnumber neurons by about 50 to one. Glial cells are the most common cells found in primary brain tumors.

When a person is diagnosed with a brain tumor, a biopsy may be done, in which tissue is removed from the tumor for identification purposes by a pathologist. Pathologists identify the type of cells that are present in this brain tissue, and brain tumors are named based on this association. The type of brain tumor and cells involved impact patient prognosis and treatment.

When You Learn You Change The Structure Of Your Brain

Riding a bike seems impossible at first. But soon you master it. How? As you practice, your brain sends “bike riding” messages along certain pathways of neurons over and over, forming new connections. In fact, the structure of your brain changes every time you learn, as well as whenever you have a new thought or memory.

This Blog Describes The Science Of The Heart That You Do Not Hear In The Text Books The More You Learn About The Heart The More You Will Want To Make It Strong As Possible

Everyone knows his or her heart is important, “if it stops, you stop”. But there’s a LOT more to your heart than just a pump. Science is finally catching up with lots of religious texts and philosophers of old that had the heart at the center of our being/soul and where thought came from. Your heart actually sends far more signals to your brain, then your brain sends to your heart. Most of the things I’ll be talking about came from this research article: Check it out for a much more in-depth study. As one learns more about this amazing organ, it will help in many different ways and you might see why training it is more important than you think. HeartMath studies define a critical link between the heart and brain. The heart is in a constant two-way dialog with the brain. Our emotions change the signals the brain sends to the heart and the heart responds in complex ways. Research has shown that the heart communicates to the brain in four major ways: neurologically , biochemically , biophysically and energetically . Communication along all these conduits significantly affects the brain’s activity. Moreover, research shows that messages the heart sends the brain can also affect performance.The heart communicates with the brain and body in four ways:

  • Neurological communication
  • Biochemical communication
  • Energetic communication

What Is Brainstem Death

Steve Jobs Quote: âWhatever you do, you must never let the ...

Brainstem death means a person has no brainstem functions. It occurs when something permanently damages the brainstem or cuts off the brains blood or oxygen supply.

Because the brainstem controls essential life functions, someone who experiences brainstem death cannot regain consciousness. They need artificial life support to remain alive. This condition is sometimes also called brain death.

What Does The Left Side Of The Brain Control

The left side of the brain is generally dominant for language and other logical tasks. This side of the brain is also used for math or various calculations, according to the University of Washington. The left side of the brain also controls muscles on the right side of the body. Sensory information from the bodys right side crosses over to the left side of the brain.

The ability to form words primarily lies in the left hemisphere, states the National Institute of Neurological Disorders and Stroke. Both hemispheres are divided into sections, or lobes, which specialize in different functions. The Brocas area, which is found on the left frontal lobe, enables thoughts to be transformed into words.

The left hemisphere of around 95 percent of right-handed individuals and 60 to 70 percent of left-handed persons is dominant for language, explains the University of Washington. The two specific areas of the brain that are important for language are named the Brocas area and Wernickes area.

As most of the signals from the brain to the body and vice versa cross over when reaching the brain, both left and right hemispheres control the opposite side of the body, notes the NINDS. Thus, when the left hemisphere is damaged, the right part of the body is affected. For instance, a stroke in the left hemisphere usually leaves the right arm and leg paralyzed.

What Is The Medulla Oblongata And What Does It Do

For most of the 18th century, the medulla oblongata was thought to simply be an extension of the spinal cord without any distinct functions of its own. This changed in 1806, when Julien-Jean-Cesar Legallois found that he could remove the cortex and cerebellum of rabbits and they would continue to breathe. When he removed a specific section of the medulla, however, respiration stopped immediately. Legallois had found what he believed to be a “respiratory center” in the medulla, and soon after the medulla was considered to be a center of vital functions .

Over time, exactly which “vital functions” were linked to the medulla would become more clear, and the medulla would come to be recognized as a crucial area for the control of both cardiovascular and respiratory functions. The role of the medulla in cardiovascular function involves the regulation of heart rate and blood pressure to ensure that an adequate blood supply continues to circulate throughout the body at all times. To accomplish this, a nucleus in the medulla called the nucleus of the solitary tract receives information from stretch receptors in blood vessels. These receptors—called baroreceptors—can detect when the walls of blood vessels expand and contract, and thus can detect changes in blood pressure.

What Controls Heart Rate

Heart rate is controlled by the two branches of the autonomic nervous system. The sympathetic nervous system and the parasympathetic nervous system . The sympathetic nervous system releases the hormones to accelerate the heart rate. The parasympathetic nervous system releases the hormone acetylcholine to slow the heart rate. Such factors as stress, caffeine, and excitement may temporarily accelerate your heart rate, while meditating or taking slow, deep breaths may help to slow your heart rate. Exercising for any duration will increase your heart rate and will remain elevated for as long as the exercise is continued. At the beginning of exercise, your body removes the parasympathetic stimulation, which enables the heart rate to gradually increase. As you exercise more strenuously, the sympathetic system kicks in to accelerate your heart rate even more. Regular participation in cardiovascular exercise over an extended period of time can decrease your resting heart rate by increasing the hearts size, the contractile strength and the length of time the heart fills with blood. The reduced heart rate results from an increase in activity of the parasympathetic nervous system, and perhaps from a decrease in activity of the sympathetic nervous system.

Ventricles And Cerebrospinal Fluid

Learn How To Control Your Mind (USE This To BrainWash Yourself)

Deep in the brain are four open areas with passageways between them. They also open into the central spinal canal and the area beneath arachnoid layer of the meninges.

The ventricles manufacture cerebrospinal fluid, or CSF, a watery fluid that circulates in and around the ventricles and the spinal cord, and between the meninges. CSF surrounds and cushions the spinal cord and brain, washes out waste and impurities, and delivers nutrients.

The Autonomic Nervous System

The autonomic nervous system is responsible for controlling many physiological functions. It induces the force of contraction of the heart and its heart rate. In addition, it controls the peripheral resistance of blood vessels. The ANS has both sympathetic and parasympathetic divisions that work together to maintain balance.

The Human Heart Reacts Strongly To Negative Emotions

Health studies have proved that intense anger has an adverse effect on the heart, increasing the risk of a heart attack by five times. Intense grief is also extremely unhealthy. You are 21 more times more likely to have a heart attack the day immediately after you have lost a loved one. Studies have shown that people who have suffered prolonged stressful situations, such as soldiers, combat veterans, doctors, all have higher rates of heart problems than the rest of the population.

On an ECG readout, if we are under stress, our heartbeat shows up in a series of jagged and erratic lines. This is called an incoherent heart rhythm pattern. This means that our autonomic nervous system is out of sync with each other. Scientists liken this to driving a car and having one foot on the gas and the other on the brake simultaneously.

Lobes Of The Brain And What They Control


Each brain hemisphere has four sections, called lobes: frontal, parietal, temporal and occipital. Each lobe controls specific functions.

  • Frontal lobe. The largest lobe of the brain, located in the front of the head, the frontal lobe is involved in personality characteristics, decision-making and movement. Recognition of smell usually involves parts of the frontal lobe. The frontal lobe contains Brocas area, which is associated with speech ability.
  • Parietal lobe. The middle part of the brain, the parietal lobe helps a person identify objects and understand spatial relationships . The parietal lobe is also involved in interpreting pain and touch in the body. The parietal lobe houses Wernickes area, which helps the brain understand spoken language.
  • Occipital lobe. The occipital lobe is the back part of the brain that is involved with vision.
  • Temporal lobe. The sides of the brain, temporal lobes are involved in short-term memory, speech, musical rhythm and some degree of smell recognition.
