Question

which part of the brain serves as a center for relaying impulses from the eyes, ears, and skin to the cerebrum?
a hypothalamus
b cerebrum
c pons
d thalamus

Explanation:

The thalamus is a major relay center in the brain. It receives sensory information (such as from the eyes - visual impulses, ears - auditory impulses, skin - tactile impulses) and then relays this information to the appropriate areas of the cerebrum. The hypothalamus is mainly involved in regulating body temperature, hunger, thirst, etc. The cerebrum is the site where the final processing of sensory and motor information occurs (not a relay center). The pons is involved in functions like sleep, respiration regulation, and acting as a bridge for nerve signals between different parts of the brain.

Answer:

D. thalamus
