Verified
Identify the structures that receive axons from the vestibular nucleus of medulla. (Check all that apply.)
A) Cerebellum
B) Extrinsic eye muscles
C) Semicircular canals
D) Thalamus
Vestibular Nucleus
A cluster of neurons in the brainstem that plays a crucial role in processing information related to balance and spatial orientation from the inner ear.
Extrinsic Eye Muscles
The six muscles located outside the eye that control its movement and positioning.
Cerebellum
A part of the brain located at the back of the skull, responsible for coordinating voluntary movements and maintaining balance and posture.

Final Answer :
A, B, D
Explanation :
The vestibular nucleus of the medulla sends axons to the cerebellum (A) for balance and coordination, to the extrinsic eye muscles (B) via the medial longitudinal fasciculus for the vestibulo-ocular reflex, and to the thalamus (D) for conscious perception of balance. The semicircular canals (C) send information to the vestibular nucleus, not the other way around.
