Special visceral efferent carries all the cranial nerve except
a) Facial
b) Vagus nerve
c) Olfactory
d) Glosso-pharyngeal
Answer: Olfactory
Explanation:
Special visceral efferent (SVE) refers to efferent nerves that provide motor innervations to the muscles of the pharyngeal arches in humans.
The only nerves containing SVE fibers are cranial nerves: the trigeminal nerve (V), the facial nerve (VII), the glosso-pharyngeal nerve (IX), the vagus nerve (X) and the accessory nerve (XI).
