Of The Brain That Controls Muscle Movement
Thanks to our brain we can plan, eat, run and even smile. It is through the complex but fascinating functions of the cerebral motor cortex that we carry out various actions on a daily basis. It is a part of our brain that helps us control, execute, and plan movement.
In addition, it allows us to react to stimuli, which is essential for our survival. But this part of our brain does not act alone. These movements can happen thanks to the various connections and association with other areas of our body.
Through the article we will talk about the Part of the brain that controls muscle movement, we will see: what is its location and what are its structures and functions. In addition to associated pathologies when there is an injury or when it does not work properly. Lets explore the motor cortex, also called the motor cortex.
How Does The Brain Work
The brain sends and receives chemical and electrical signals throughout the body. Different signals control different processes, and your brain interprets each. Some make you feel tired, for example, while others make you feel pain.
Some messages are kept within the brain, while others are relayed through the spine and across the bodys vast network of nerves to distant extremities. To do this, the central nervous system relies on billions of neurons .
What Part Of The Brain Controls Balance
Standing upright, maintaining balance, and walking are all pretty natural processes to us. We dont consciously think about balance during our daily activities.
But have you ever wondered how you manage to stand on one foot? Or perform any sports activity? Or how you dont fall down every time you stumble? Today were going to explore what part of the brain controls balance.

The Functions Of The Cerebellum
Thus, it was considered that the task of the cerebellum was, basically, to make it possible for us to maintain balance, for us to coordinate simple and complex movements and, in general, for the muscles of our body to respond faithfully and effectively to the orders issued by the brain.
For example, one of the main symptoms of changes in the cerebellum was considered to be loss of balance after drinking too much alcohol.
However, in recent years it has been discovered that the idea that the role of the cerebellum has to do with motor coordination is too simplistic. Thus, the cerebellum is not only involved in motor processes, but also plays an important role in many other functions.
Related Problems And Disorders
As we have indicated previously, the motor cortex is a very important brain region when it comes to being able to carry out practically any action. That is why an injury to these brain areas can have severe repercussions on the lives of patients.
One of the problems that the injury or destruction of the cortex or motor area can generate is paralysis and loss of mobility, whether in a specific part of the body, in a half body or in the whole body.
Hemiplegia or tetraplegia may appear. If the injury is only in one hemisphere, the paralysis will occur contralaterally: that is, if the right motor cortex is injured, the left hand will be paralyzed.
With regard to secondary motor areas, the effects of injury to them often alter the ability to perform movements in a coordinated and sequential manner. We are talking about the emergence of possible apraxias, or aphasias or dysarthria when we refer to problems in the production of the movements necessary to communicate.
Agrafia can also occur, as the movements necessary to write cannot be carried out correctly, eating problems or even visual problems due to the lack of proper regulation of the movement of the facial organs and muscles.

Which Part Of The Brain Is Associated With Coordination Motor Activity And Preventing Movement Errors
The cerebellum is a major structure of the hindbrain that is located near the brainstem. This part of the brain is responsible for coordinating voluntary movements. It is also responsible for a number of functions including motor skills such as balance, coordination, and posture.
Medulla OblongataThis portion of the brain stem is located just above the spinal cord. It regulates vital functions, such as heartbeat and breathing.
What Part Of The Brain Controls Voluntary Movement
The cerebellum controls voluntary movement. It is located at the back of the head and also controls muscle coordination and balance. Damage to this part of the brain is known to cause problems in these areas. According to Johns Hopkins Medicine, the cerebellum is one of three primary areas of the brain.

What Part Of The Brain Controls Muscle Tone
Correspondingly, what part of the brain is responsible for muscle tone?
The cerebellum is located at the back of the head. Its function is to coordinate voluntary muscle movements and to maintain posture, balance, and equilibrium.
Subsequently, question is, how does the cerebellum control muscle tone? The palaeocerebellum is connected to the spinal cord and controls postural muscle activity by influencing muscle tonus. To play its role in maintaining body posture, a muscle must be tensed. The cerebellum therefore controls muscle tension at all times while releasing those muscles required to execute movements.
Also to know is, what part of the brain is responsible for language?
Language. In general, the left hemisphere of the brain is responsible for language and speech and is called the “dominant” hemisphere. The right hemisphere plays a large part in interpreting visual information and spatial processing.
What part of the brain controls motor skills?
The cerebellum is located behind the brain stem. While the frontal lobe controls movement, the cerebellum fine-tunes this movement. This area of the brain is responsible for fine motor movement, balance, and the brain’s ability to determine limb position.
The Cerebellum And Motor Coordination
Old ideas about the role of the cerebellum as the focal point for muscle activation have not been disproved.
Today it is still considered that this structure has a leading role in the coordination of movements, maintenance of balance and monitoring of neuronal signals aimed at activating muscles.
As the cerebellum is connected to many areas of the brain, it crosses the motor information elaborated in the higher regions of the brain with the more concrete and operational motor information aimed at activating muscle fibers, and checks that there are no inconsistencies between the two.
In addition, there is a debate generated around the possibility that one of the functions of the cerebellum is motor learning, that is, the ability to refine a pattern of movements so that it is perfected more and more.
The cerebellum has connections with different parts of the central nervous system, thanks to which it carries out multiple functions:
In the different connections of the cerebellum with the other areas, it almost always acts as a regulator. It records information and regulates the movements of different parts of the body, depending on the structure to which it is connected. Functions such as maintaining balance or learning a movement could be difficult if these pathways are broken.

What Does Frontal Lobe Do
The frontal lobes are important for voluntary movement, expressive language and for managing higher level executive functions. Executive functions refer to a collection of cognitive skills including the capacity to plan, organise, initiate, self-monitor and control ones responses in order to achieve a goal.
What Is The Gray Matter And White Matter
Gray and white matter are two different regions of the central nervous system. In the brain, gray matter refers to the darker, outer portion, while white matter describes the lighter, inner section underneath. In the spinal cord, this order is reversed: The white matter is on the outside, and the gray matter sits within.
Gray matter is primarily composed of neuron somas , and white matter is mostly made of axons wrapped in myelin . The different composition of neuron parts is why the two appear as separate shades on certain scans.
Each region serves a different role. Gray matter is primarily responsible for processing and interpreting information, while white matter transmits that information to other parts of the nervous system.

What Are Axons Responsible For
Summary. An axon is a thin fiber that extends from a neuron, or nerve cell, and is responsible for transmitting electrical signals to help with sensory perception and movement. Each axon is surrounded by a myelin sheath, a fatty layer that insulates the axon and helps it transmit signals over long distances.
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.

How Does The Cerebellum Control Coordination And Balance
The cerebellum is important for making postural adjustments in order to maintain balance. Through its input from vestibular receptors and proprioceptors, it modulates commands to motor neurons to compensate for shifts in body position or changes in load upon muscles. The cerebellum is important for motor learning.
In What Regions Is The Motor Cortex Divided
The motor cortex integrates various areas, through which movement is possible. Lets look at them:
- Primary motor cortex. It is the main area that is responsible for generating the nerve impulses that are needed for the production of voluntary movement. In addition, it is responsible for sending orders to the voluntary muscles of the body. In this way, they contract or tighten. It is a region with a low excitation threshold.
- Supplementary motor area. It consists of an area that coordinates the movements of the postures. Thus, the sequence of movements in large muscle groups collaborates.
- Premotor areas. They are areas with a high threshold of excitation. In addition, it is responsible for storing movements that come from past experiences.
Thus, it coordinates and at the same time programs the sequence of movements and the activity of the primary motor cortex. It is located in front of the primary motor cortex and close to Sylvian fissure. It is also related to the movements required for speech.

The Part Of The Brain Controlling: Balance And Hearing
The processing of sound happens in the temporal lobes which are a part of the cerebrum. The audio stimuli come through the ear and go directly into the primary auditory cortex located in the temporal lobes.
But how does the temporal lobe affect balance?
Have you ever heard a loud noise and reflexively found yourself moving away from the source of the noise?
Thats the temporal lobe at work. Your temporal lobe is directly connected to the cerebellum by neural pathways. This connection enables a quick reaction to loud noise.
What Are Control And Coordination
We humans have five senses of organs in our body, eyes, nose, tongue and skin, called receptors. In other words, control and coordination in humans take place through the nervous system and hormonal system called the Endocrine System. A receptor is a group of cells in the sense of an organ acting sensitive to a particular type of action or message in the form of light, sound or heat. All receptors send messages to our body system in the form of electrical impulses to the spinal cord and brain through sensory nerves. Then there are motor nerves transmitting a response from the brain and spinal cord to effectors. Here effectors are muscles and glands.
In layman’s language, the real meaning of control and coordination is the process of the body working in a systematic manner. Every small and big process happening in our body is quite complicated, and still, our body works efficiently. Our body nervous systems are connected to each other and send messages to every part of the body to conduct action.

What Controls The Bodys Balance
In addition to the cerebellum, two crucial structures in maintaining balance are the inner ear and the vestibular cranial nerves.
Located in the inner ear, the vestibular system provides your brain with the necessary information for motion, head position, and spatial orientation.
It also plays a role in your motor functions that are involved in keeping your balance, stabilizing your head and body during movement, and also helps maintain your posture.
The vestibular system is absolutely essential for your bodys equilibrium, thus making it a vital part aiding you in balance.
Damage to any part of the brain related to balance isnt inherently life-threatening, however, it can result in jerky and uncoordinated movements if the damage is severe.

Blood Supply To The Brain
Two sets of blood vessels supply blood and oxygen to the brain: the vertebral arteries and the carotid arteries.
The external carotid arteries extend up the sides of your neck, and are where you can feel your pulse when you touch the area with your fingertips. The internal carotid arteries branch into the skull and circulate blood to the front part of the brain.
The vertebral arteries follow the spinal column into the skull, where they join together at the brainstem and form the basilar artery, which supplies blood to the rear portions of the brain.
The circle of Willis, a loop of blood vessels near the bottom of the brain that connects major arteries, circulates blood from the front of the brain to the back and helps the arterial systems communicate with one another.
Ventricles And Cerebrospinal Fluid
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.

What Is A Nervous System
The nervous system consists of nerve fibres and nerve cells transmitting messages to different parts of the body. It is a vital system found in animals and humans synchronizing its function by passing out signals to and from different parts of the body. This nervous system coordinates with the endocrine system. This system of control and coordination is brought after the involvement of various internal systems.
How Does The Cerebellum Affect Coordination
Maintaining balance: The cerebellum has special sensors that detect shifts in balance and movement. It sends signals for the body to adjust and move. Coordinating movement: Most body movements require the coordination of multiple muscle groups. The cerebellum times muscle actions so that the body can move smoothly.

There Are Three Types Of Nerves Systems:
Sensory Nerve: It carries impulses from the sense organs to the brain
Motor Nerve: It brings messages from the brain to the sense organs
Relay Nerve: It works on both functions
Under the nervous system, there is a neuron acting as the structural and functional unit. It receives and transmits electrical nerve impulses. Neural control and coordination is an important part of human function. Neuron comprises of:
The cell body has a nucleus and granular cytoplasm called Nissl’s Granules. Dendrites carry several branches and look like finger projections transmitting nerve impulse towards the cell body. Axon arises from the cell body branched as the distal end. Cells of the axon are called Schwann cells covering myelin sheath.
Messages transmitted through this nervous system are in the form of electrical impulses and are called nerve impulses. In this process, dendrites pick messages and send them to the cell boy and then to the axon. The axon then sends these messages to neurons through a junction called a synapse.
This process of biology control and coordination happens in the friction of time making the person react to the situation.
