The pterygoid bone, os pterygoideum, is paired and situated medial to the pterygoid process of the basisphenoid, to which it is fused. It projects cau- doventrally to form the hamulus, hamulus ptery- goideus (Figs. 2-7 to 2-10), for the attachment of muscles. The ethmoid bone, os ethmoidale (Figs. 2-9 to 2- 11), is a complex of bone and cartilage scrolls that is located between the facial and cranial portions of the skull. It is only visible within the nasal cavity. Although unpaired as a unit it develops as right and left dorsal, middle, and ventral nasal conchae, con- cha nasalis dorsalis, media, et ventralis. A transverse cribriform plate, lamina cribrosa, through which the. Fig. 2-10.
