Embryonic development of the head and neck: part 4, organs of special sense.
A synopsis of the embryonic development of the eye, the ear, and the olfactory organ and taste buds is presented. The eye is discussed in terms of the sensory and nonsensory protions of the eyeball and of such associated structures as the extrinsic eye muscles, eyelids, conjuctiva, and lacrimal apparatus. The embryology of the internal, middle, and external ear is reviewed, as well as positional changes of both the eye and ear relative to other sturctures of the head and neck. Various congenital defects affecting the eye and ear are also discussed.
