paired arched columns that bear the gills in lower aquatic vertebrates and that, in the embryos of higher vertebrates, appear in comparable form before subsequent modification into structures of the head and neck. In humans they are usually called pharyngeal arches because gills do not develop. Each contains a cartilaginous bar, consisting of right and left halves. The first arch (mandibular a.) differentiates into the sphenomandibular and anterior malleolar ligaments, malleus, and incus; the second (hyoid a.) into the stapes, styloid process, stylohyoid ligament, lesser horn of the hyoid bone, and cranial part of the hyoid body; the third into the greater horn of the hyoid bone and the caudal part of its body; and the fourth and sixth into the laryngeal cartilages. In the human embryo, the sixth arch is actually the fifth in number but is so named for reasons of comparative anatomy and evolution; it does not appear on the surface. Called also visceral a's.
