The oculomotor nerve, which originates in the midbrain, primarily controls most of the eye muscles, enabling eye movement and pupil constriction. The brainstem, particularly the medulla and pons, plays a crucial role in maintaining posture by integrating sensory information and coordinating muscle activity. Additionally, the cerebellum helps fine-tune motor control and balance, influencing both eye movements and overall posture.
Action potential in the brain
The spinal cord connects the brain to the peripheral muscles in the body. It is responsible for transmitting messages to and from the brain that control movement and sensation in the rest of the body.
Cerebrum
The brain stem is responsible for regulating the urinary system by controlling functions like urination and bladder control. It sends signals to the bladder muscles when it's time to urinate and also relaxes the muscles in the urethra to allow urine to pass.
You primarily use the cerebellum when trying to balance on one foot. The cerebellum coordinates muscular activity and helps maintain balance and posture. Additionally, sensory input from the inner ear and proprioceptive receptors in the joints and muscles are also involved in balance control.

The biggest part of the brain is the cerebrum. The cerebrum makes up 85% of the brain's weight. The cerebrum is the thinking part of the brain and it controls your voluntary muscles - the ones that move when you want them to. The cerebellum is a motor region of the brain, dealing with the subconscious movements of the muscles. This butterfly-shaped section is the second largest area of the brain. The cerebellum deals with coordination, posture, and balance.

Several different muscles are used for maintaining upright posture. Muscles in the shoulder area play a big part as well as spinal muscles.
The cerebellum (infratentorial or 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 cerebellum, located at the back of the brain, is the part responsible for coordinating movements. It receives information from the sensory systems and integrates it to control balance, posture, and voluntary movements.

Many parts of the brain control your muscles. There is a part of the brain called the Central Nerve System or CNS located towards the center of the brain. This are controls your nerves and movement. Everytime you want to move a body part, your brain sends a message lightning speed to your nerves and that is how you move. Without the Central Nerve System, you would be paralized and unable to move.
The brain stem is responsible for regulating the urinary system by controlling functions like urination and bladder control. It sends signals to the bladder muscles when it's time to urinate and also relaxes the muscles in the urethra to allow urine to pass.
