The cerebellum helps refine and coordinate muscle movements.
Cerebrum
The frontal lobe controls motor functions and permits voluntary muscle control. The brain stem
Cerebellum controls the coordination of voluntary motor movement, balance and equilibrium and muscle tone.
Michael your dum and stop looking at nino your her off really bad so beat it boy. i think whoever wrote you this is the one who is you know what.
The motor neuron and the muscle fiber it controls constitute a motor unit. This functional unit is essential to the process of muscle contraction and movement in the body. When the motor neuron sends signals to the muscle fiber, it results in the activation and coordination of muscle fibers to produce movement.
The primary muscle that controls elbow movement is the biceps brachii, which flexes the elbow when contracted. Additionally, the triceps brachii is responsible for extending the elbow. These muscles work in coordination to facilitate various movements of the arm.
The part of the brain that controls muscle coordination and posture is the cerebellum. It plays a crucial role in fine-tuning motor movements, maintaining balance, and ensuring smooth execution of voluntary actions. By integrating sensory information from the body, the cerebellum helps coordinate movements and maintain posture during various activities.
The cerebellum is the part of the brain responsible for coordinating balance and muscle activity. It receives sensory input from the inner ear and other parts of the body to help maintain equilibrium and posture.
The cerebellum is involved in the coordination of voluntary motor movement, balance and equilibrium and muscle tone. It is located just above the brain stem and toward the back of the brain. It is relatively well protected from trauma compared to the frontal and temporal lobes and brain stem.

Ataxia: the lack of muscle coordination during voluntary movement.
The cerebellum is the motor movements center of the brain, governing posture, coordination, balance, speech, etc.
