1, 2, 7, 10
1, 2, 8, 9
1, 2, 8, 11

1. what conducts nerve impulses to and from the brain and serves as a reflex center for some sensory information without input from the brain?

spinal cord
medulla oblongata
meninges
pons

Explanation:

Question 59

Special senses (vision, hearing, taste, smell, equilibrium) are served by specific cranial nerves. Cranial nerve 1 (Olfactory) for smell, 2 (Optic) for vision, 8 (Vestibulocochlear) for hearing/equilibrium, and 9 (Glossopharyngeal) for taste (and other functions). So the correct set is 1, 2, 8, 9.

The spinal cord transmits nerve impulses between brain and body, and mediates spinal reflexes (like knee - jerk) without brain input. Medulla controls vital functions, meninges are protective layers, pons relays signals. So the answer is spinal cord.

Answer:

1, 2, 8, 9
