Four cranial nerves have Branchial Efferent components (or a BE classification). Why? -There are four pharyngeal arches from which muscles arise during events described in embryology. -These muscles are not derived from somites (hence no “S” in their classification). -The important concept for...

and vagal nerves —are formed by a medial component that differentiates from the dorsomedial surface of migrating bands of neural crest associated with each of the developing branchial arches and with one or more lateral components that arise from epibranchial placodes located immediately dorsal and ...
Muscular and nervous system morphologies are also organized following these metameric patterns, with distinct differences between head and trunk; branchiomeric nerves innervating pharyngeal arches are superficial to spinal nerves innervating somite derivatives. Hypobranchial muscles originate from rostral somites...
Branchial arch, one of the bony or cartilaginous curved bars on either side of the pharynx (throat) that support the gills of fishes and amphibians; also, a corresponding rudimentary ridge in the embryo of higher vertebrates, which in some species may fo
