| penis bone | A bone of variable size and shape, located in the glans penis or glans clitoridis of all animals, except man, ungulates, elephants, whales, and a few others; it is particularly well developed in carnivora, and in the dog may reach a length of more than 10 cm; its size and shape are often a characteristic of a species. Synonym: baculum, penis bone. (05 Mar 2000) |

| reticulated bone | Bony tissue characteristic of the embryonal skeleton, in which the collagen fibres of the matrix are arranged irregularly in the form of interlacing networks. Synonym: nonlamellar bone, reticulated bone. (05 Mar 2000) |
| Goethe's bone | A large sutural bone occasionally found detached from the anterior portion of the os interparietale. Synonym: Goethe's bone. (05 Mar 2000) |
| membrane bone | A bone that develops embryologically within a membrane of vascularised primitive mesenchymal tissue without prior formation of cartilage. (05 Mar 2000) |
| cheek bone | A quadrilateral bone which forms the prominence of the cheek; it articulates with the frontal, sphenoid, temporal, and maxillary bone. Synonym: os zygomaticum, cheek bone, jugal bone, mala, malar bone, os malare, yoke bone, zygoma. (05 Mar 2000) |
| perichondral bone | In the development of a long bone a collar or cuff of osseous tissue forms in the perichondrium of the cartilage model; the connective tissue membrane of this perichondral bone then becomes periosteum. Synonym: periosteal bone. (05 Mar 2000) |
| mesethmoid bone | In comparative anatomy, the bone present in some species as the most anterior bone of the floor of the braincase. (05 Mar 2000) |
| periosteal bone | In the development of a long bone a collar or cuff of osseous tissue forms in the perichondrium of the cartilage model; the connective tissue membrane of this perichondral bone then becomes periosteum. Synonym: periosteal bone. (05 Mar 2000) |
| periotic bone | The part of the temporal bone that contains the structures of the inner ear and the second part of the internal carotid artery; in antenatal life it appears as a separate ossification centre. Synonym: pars petrosa ossis temporalis, periotic bone, petrosal bone, petrous pyramid. (05 Mar 2000) |
| greater horn of hyoid bone | The larger and more lateral of the two processes on either side of the hyoid bone. Synonym: cornu majus ossis hyoidei. (05 Mar 2000) |
| greater multangular bone | Origin: NL, fr. Gr. A little table, an irregular four-sided figure, dim. Of a table, for; (see Tetra-) + foot, akin to foot; hence, originally, a table with four feet. See Foot. 1. <geometry> A plane figure bounded by four right lines, of which no two are parallel. 2. <anatomy> A bone of the carpus at the base of the first metacarpal, or thumb. A region on the ventral side of the brain, either just back of the pons Varolii, or, as in man, covered by the posterior extension of its transverse fibres.

| greater wing of sphenoid bone | Strong squamous processes extending in a broad superolateral curve from the body of the sphenoid bone. The greater wing presents these suraces (facies): 1) cerebral surface: forms anterior third of the floor of the lateral portions of the middle cranial fossa; 2) temporal surface: forms the deepest portion of the temporal fossa; 3) infratemporal surface, forms the "roof" of the infratemporal fossa; 4) orbital surface: forms posterolateral wall of orbit. The greater wing forms the inferior border of the supraorbital fissure, and is perforated at its root by foramina rotundum ovale, and spinosum and the pterygoid canal. Synonym: ala major ossis sphenoidalis, ala temporalis. (05 Mar 2000) |
| rider's bone | Heterotopic bone ossification of the tendon of the adductor longus muscle from strain in horseback riding. Synonym: cavalry bone, exercise bone. (05 Mar 2000) |
| metacarpal bone | One of the metacarpal bones, five long bones (numbered I to V, beginning with the bone on the radial or thumb side) forming the skeleton of the metacarpus or palm; they articulate with the bones of the distal row of the carpus and with the five proximal phalanges. Synonym: os metacarpale. (05 Mar 2000) |
| peroneal bone | A long bone in the lower leg that is adjacent to the tibia. The fibula supports approximately 1/6th of the body weight and produces the lateral (outer) prominence of the ankle. (27 Sep 1997) |
