Special visceral efferent
（重定向自Branchiomotor）
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.
Some sources prefer the term "branchiomotor", or "branchial efferent".
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).
