| sphenoid | 1. Wedge-shaped; as, a sphenoid crystal. 2. <anatomy> Of or pertaining to the sphenoid bone. <anatomy> Sphenoid bone, an irregularly shaped bone in front of the occipital in the base of the skull of the higher vertebrates. It is composed of several foetal bones which become united the adult. See Alisphenoid, Basisphenoid, Orbitosphenoid, Presphenoid. Origin: Gr.; a wedge + form: cf. F. Sphenoide. 1. <chemistry> A wedge-shaped crystal bounded by four equal isosceles triangles. It is the hemihedral form of a square pyramid. 2. <anatomy> The sphenoid bone.

| sphenoid bone | A bone of most irregular shape occupying the base of the skull; it is described as consisting of a central portion, or body, and six processes: two greater wings, two lesser wings and two pterygoid processes; it articulates with the occipital, frontal, ethmoid, and vomer, and with the paired temporal, parietal, zygomatic, palatine and sphenoidal concha bones. Synonym: os sphenoidale, sphenoid. (05 Mar 2000) |
