Question

question 1 of 10
the optic nerve:

a. carries impulses from the eye to the thalamus.

b. carries sensory input from the temporal lobe.

c. connects the parietal lobe to the eye.

d. changes auditory stimuli into nerve impulses.

Explanation:

• Option A: The optic nerve transmits visual (nerve) impulses from the retina (eye) to the thalamus (a structure in the brain involved in relaying sensory information), which is correct.
• Option B: The temporal lobe is involved in auditory processing and other functions, not sending sensory input to the optic nerve. The optic nerve carries signals away from the eye, not receiving from the temporal lobe.
• Option C: The parietal lobe is related to sensory integration (like touch, spatial awareness) and does not connect to the eye via the optic nerve. The optic nerve connects the eye to the brain (thalamus/visual cortex), not the parietal lobe to the eye.
• Option D: Auditory stimuli are processed by structures like the cochlea and auditory nerve, not the optic nerve (which is for visual stimuli).

Answer:

A. carries impulses from the eye to the thalamus.
