Question

Which statement is true about deep cerebellar nuclei?

A. Denate nuclei send information to lower motor neurons in the spinal cord and brainstem
B. Interposed nuclei coordinate antigravity muscles and other synergies involved with standing and walking
C. Interposed nuclei send information to the premotor cortex
D. Denate nuclei are responsible for planning, initiation, and control of volitional movement
E. Fastigial nuclei modulate muscle stretch reflexes of distal muscle groups

Answer 1

Denate nuclei in the deep cerebellar area are responsible for the planning, initiation, and control of volitional movement, which is the correct statement regarding their function.

Step-by-step explanation:

The correct statement about deep cerebellar nuclei is: D. Denate nuclei are responsible for planning, initiation, and control of volitional movement. The denate nuclei project to the premotor and motor cortices and play a critical role in the planning and initiation of voluntary movements. They are not responsible for directly sending information to lower motor neurons. The interposed nuclei, which include the emboliform and globose nuclei, have a role in controlling and coordinating movements, but do not send information directly to the premotor cortex; instead, they influence movements more indirectly. The fastigial nuclei are implicated in the modulation of muscle tone and balance, especially tied to antigravity muscle groups, and are not primarily focused on distal muscle group reflexes.
