Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Muscle coordination, balance, and posture are controlled by which part of the brain?
A
Cerebrum
B
Cerebellum
C
Spinal cord
D
Medulla
Explanation: 

Detailed explanation-1: -The cerebellum is the part of the brain most involved in coordinating sequences of movements. It also controls balance and posture.

Detailed explanation-2: -Cerebellum. This is the back of the brain. It coordinates voluntary muscle movements and helps to maintain posture, balance, and equilibrium.

Detailed explanation-3: -The cerebellum is located behind the brain stem. While the frontal lobe controls movement, the cerebellum “fine-tunes” this movement. This area of the brain is responsible for fine motor movement, balance, and the brain’s ability to determine limb position.

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.

Detailed explanation-5: -Cerebellum: is located under the cerebrum. Its function is to coordinate muscle movements, maintain posture, and balance. Brainstem: acts as a relay center connecting the cerebrum and cerebellum to the spinal cord.
