which of the brain structures coordinates voluntary movement?
243078
The cerebellum (back of brain) is located at the back of the head. Its function is to coordinate voluntary muscle movements and to maintain posture, balance, and equilibrium.

The motor homunculus is a topographic representation of the body parts and its correspondents along the precentral gyrus of the frontal lobe. While the sensory homunculus is a topographic representation of the body parts along the postcentral gyrus of the parietal lobe.

The right cerebral hemisphere controls movement of the left side of the body. Depending on the severity, a stroke affecting the right cerebral hemisphere may result in functional loss or motor skill impairment of the left side of the body.

Specifically, in left-handers, the motor cortex in the right side of the brain (the left side of the body is controlled by the right side of the brain, and vice versa) is dominant for fine motor behavior. In contrast, in right-handers, the left motor cortex is better at fine motor tasks such as writing.

The cerebellum is located underneath the backside of the cerebrum, and governs balance and fine motor movements. Its main function is maintaining coordination throughout the body.

Proprioception is transmitted to the cerebellum via spinocerebellar tracts. This information is used by the cerebellum to regulate muscle tone, posture, locomotion, and equilibrium.

Rotate this 3D model to see the four major regions of the brain: the cerebrum, diencephalon, cerebellum, and brainstem. The brain directs our body's internal functions. It also integrates sensory impulses and information to form perceptions, thoughts, and memories.

The Medulla Oblongata controls our bodies' involuntary actions, like breathing, digestion, swallowing and many more. Thus, the Cerebrum of our brain is helpful to us in solving puzzles and tricks.

The nervous system is the human organ system that coordinates all of the body's voluntary and involuntary actions by transmitting signals to and from different parts of the body. The nervous system has two major divisions, called the central nervous system (CNS) and the peripheral nervous system (PNS).

A vast network of nerve tracts in the central nervous system (CNS) which spans the cerebral cortex, brainstem, cerebellum, and spinal cord control the initiation and modulation of movements. The nerves in the CNS which carry the impulses for movement are known as upper motor neurons (UMN).

The Biggest Part: the Cerebrum The cerebrum is the thinking part of the brain and it controls your voluntary muscles — the ones that move when you want them to. So you need your cerebrum to dance or kick a soccer ball.
