Smoothes and coordinates skilled skeletal muscle movement; also posture and balance or equilibrium.
A
medulla oblongata
B
cerebellum
C
cerebral cortex
D
corpus callous
E
pineal gland
Explanation: 

Detailed explanation-1: -The cerebellum smoothes and coordinates skilled skeletal muscle movement, also posture, and balance or equilibrium. The cerebellum compares desired motor output to actual motor output and corrects any deficiencies. It is known as an error-correcting structure.

Detailed explanation-2: -Cerebellum: The cerebellum, also known as the little brain, is responsible for smooth, coordinated voluntary movements.

Detailed explanation-3: -We can deliberately order the skeletal muscles to contract, which enables us to perform movements. These voluntary movements are commanded by the motor cortex, the zone of the cerebrum located behind the frontal lobe.

Detailed explanation-4: -The cerebellum integrates this information and coordinates the planning, timing and patterning of skeletal muscle contractions during movement. The cerebellum plays a major role in the control of posture, head and eye movements.

Detailed explanation-5: -The cerebellum coordinates the muscle movements ordered by the motor cortex.
