​

Answer 2

Answer:

(b) Cerebellum is mainly associated with the maintenance of the posture.

Explanation:

• The hindbrain consists of the cerebellum and brain stem (pons varoli+ medulla oblongata).

• The cerebellum (Metacephalon) is the second-largest part of the brain.
• Like cerebral hemispheres, its upper surface is formed of grey matter and forms the cerebellar cortex and the deeper central part is the medulla formed of white matter.

• Cerebellar nuclei of grey matter are scattered in the white matter.
• The cerebellum is partially divided into three lobes: the central vermis, two lateral lobes and two outer floccular lobes. The grey matter of the cerebellum exhibits a tree-like structure called arbor vitae.

• Cerebellum maintains equilibrium and controls posture. It modulates and moderates voluntary movements initiated in the cerebrum. It is responsible for smooth, steady and coordinated body movement.

Hence (b) cerebellum is the correct answer.
