This structure coordinates balance and voluntary movements
A
corpus callosum
B
cerebellum
C
cerebrum
D
spinal cord
Explanation: 

Detailed explanation-1: -Cerebellum. This is the back of the brain. It coordinates voluntary muscle movements and helps to maintain posture, balance, and equilibrium.

Detailed explanation-2: -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.

Detailed explanation-3: -These voluntary movements are commanded by the motor cortex, the zone of the cerebrum located behind the frontal lobe. The motor cortex sends a neural message that moves through the brain stem along the spinal cord and into the neural network to the muscle being commanded.

Detailed explanation-4: -The flocculonodular lobe. It is the oldest part of the brain in evolutionary terms (archicerebellum) and participates mainly in balance and spatial orientation. Its primary connections are with the vestibular nuclei, although it also receives visual and other sensory input.
