Movements such as reaching, jumping, writing, waving your hand….all these are voluntary movements. You have finely tuned your skills to be able to make these movements when you decide to make them.
The cerebellum works in conjunction with the motor cortex to produce skilled, coordinated movements. The motor cortex initiates voluntary movements, while the cerebellum helps to smooth out and refine these movements to make them more accurate and precise. Damage to the cerebellum can lead to impairments in coordination and motor control.

Voluntary movements in the brain are controlled by the motor cortex, which is located in the frontal lobe. This area of the brain sends signals to the muscles to initiate and coordinate voluntary movements. Other parts of the brain, such as the cerebellum and basal ganglia, also play a role in coordinating and fine-tuning voluntary movements.
Frontal Lobe
CEREBRUM
The two massive motor tracts serving voluntary movements are pyramidal and corticospinal.
Voluntary movements are controlled by the motor cortex in the brain, which sends signals to the muscles through the spinal cord and peripheral nervous system. The cerebellum also plays a key role in coordinating and fine-tuning these movements to ensure smooth and precise execution. Feedback from sensory receptors helps in adjusting and refining movements as needed.
