Question

1. which of the following cranial nerves are responsible for carrying nerve impulses associated with the special senses?

○ 1, 2, 5, 8
○ 1, 2, 7, 10
○ 1, 2, 8, 9
○ 1, 2, 8, 11

1. the somatic peripheral nervous system is composed of neurons that control the \soma\ or body. they specifically control which of the following?

○ involuntary reflexes
○ muscles
○ organs
○ special senses

Explanation:

Question 104

To determine which cranial nerves carry impulses for special senses, recall: Cranial nerve 1 (Olfactory) for smell, 2 (Optic) for vision, 8 (Vestibulocochlear) for hearing/balance, and 9 (Glossopharyngeal) for taste (a special sense). So the set 1,2,8,9 includes these. Other options have nerves not related to special senses (e.g., 5 is trigeminal, 7 is facial but not primary for special senses here, 10 is vagus, 11 is accessory).

The somatic peripheral nervous system controls voluntary movements of skeletal muscles. Involuntary reflexes (spinal reflexes, but somatic also has voluntary), organs are controlled by autonomic, special senses by cranial nerves. So muscles are controlled by somatic PNS.

Answer:

1, 2, 8, 9
