Special visceral efferent

Jump to: navigation, search

Special visceral efferent (SVE) refers to efferent nerves which supply muscles which derived from the branchial arches.[1] Examples of nerves that contain SVE fibers include the trigeminal nerve, the facial nerve, the glossopharyngeal nerve, the vagus nerve, and the accessory nerve.[2]

Some sources prefer the term "branchiomotor".[3]
