To solve this problem, we need to know the number of cranial nerves in humans.
1. Cranial Nerves in Humans:
Humans have 12 pairs of cranial nerves, which originate directly from the brain and are responsible for functions such as sensory input, motor control, and autonomic functions. These nerves are numbered I to XII.
2. Evaluating the Options:
(A) 10 pairs – Incorrect (Humans have 12 pairs, not 10.)
(B) 15 pairs – Incorrect (There are 12 pairs of cranial nerves.)
(C) 12 pairs – Correct ✅ (This is the correct number of cranial nerve pairs in humans.)
(D) 13 pairs – Incorrect (Humans have 12 pairs, not 13.)
Final Answer:
The correct option is (C) 12 pairs.
S.No. | Cranial nerves | Arises from ... | Ends in ... |
---|---|---|---|
I. | Olfactory nerves | Olfactory epithelium of nasal chambers | Temporal lobes of cerebrum |
II. | Optic nerves | Retina of eyes | Cerebellum |
III. | Auditory nerves | Internal ears | Cerebrum |
IV. | Pathetic nerves | Floor of mid brain | Superior oblique muscle of eye ball |
