Buck's Handbook of Med. Sciences, VIII. 147. occiput (ok'si-put), n. [F. Pg. occiput = Sp. occipuzio = It. occipite, formerly also occipute, also occipizio, other vertebrates, a corresponding but varying part of the head or skull: as, in most mammals, only that part corresponding to the supra occipital bone itself, or from the occipital protuberance to the foramen magnum.-3. In descriptive ornith., a frequent term for the part of the head which slopes up from nucha to vertex. See diagram under bird1.-4. In herpet., the generally flat back part of the top of the head, as where, in a snake for example, the occipital plates are situated.-5. In entom., that part of the head behind the epicranium, belonging to the labial or second maxillary segment, and articulating with the thorax. It may be flat or concave, with sharp edges, or rounded and not distinctly divided from the rest of the head. The occiput properly forms an arch over the occipital foramen, by which the cavity of the head opens into that of the thorax, the foramen being closed beneath by the gula or by the submentum; but in Diptera, Hymenoptera, and Neuroptera this lower piece is not distinguished, and the whole back of the head is then called the occiput; the portion above the foramen may be distinguished as the cervix or nape.
