Question

Cerebellar circuitry coordinates behavior by

a. inhibiting inappropriate muscle groups
b. disinhibiting appropriate muscle groups
c. responding to changes in head tilt, or posture and muscle disposition
d. all of the above
e. none of the above

Answer 1

d. all of the above

Step-by-step explanation:

The main function of the cerebellum is to integrate the sensory and motor pathways. The cerebellum is connected by a large number of nerve bundles with other structures of the brain and spinal cord to integrate the information it receives, specify and control the orders that the cerebral cortex sends to the musculoskeletal system. It is also the regulator of physiological tremor.

To achieve proper posture, the cerebellum must inhibit inappropriate muscle groups, disinhibit appropriate muscle groups, respond to changes in head tilt, or posture and muscular disposition.
