Special visceral efferent

From Infogalactic: the planetary knowledge core

Jump to: navigation, search

Special visceral efferent (SVE) refers to efferent nerves that provide motor innervations to the muscles of the pharyngeal arches in humans and branchial arches in fish.^[1]

Some sources prefer the term "branchiomotor",^[2] or "branchial efferent".^[3]

The only nerves containing SVE fibers are cranial nerves: the trigeminal nerve (V), the facial nerve (VII), the glossopharyngeal nerve (IX), the vagus nerve (X) and the accessory nerve (XI).^[4]
