| bundle bone | Immature bone containing thick bundles of collagen fibres arranged nearly parallel to one another with osteocytes in between; a similar type of bone is found in regions penetrated by fibres of Sharpey, as at ligament and tendon attachments. (05 Mar 2000) |
| caecal foramen of frontal bone | <anatomy> Blind or caecal foramen of the frontal bone; the blind foramen formed immediately anterior to the crista galli by a notch at the lower end of the frontal crest and its articulation with the ethmoid bone. It is insignificant postnatally, but gives passage to vessels during development. Synonym: foramen caecum ossis frontalis, blind foramen of frontal bone, caecal foramen of frontal bone.

| cancer, bone | Cancer of the skeleton. Cancers that begin in bone are rare but it is not unusual for cancers to spread (metastasize) to bone from other parts of the body.

| vaginal process of sphenoid bone | A thin lamina of bone that extends medially under the body of the sphenoid bone from the medial lamina of the pterygoid process; it articulates with the vomer and the palatine bone. Synonym: processus vaginalis ossis sphenoidalis, sheath process of sphenoid bone. (05 Mar 2000) |
| palatine bone | An irregularly shaped bone posterior to the maxilla, which enters into the formation of the nasal cavity, the orbit, and the hard palate; it articulates with the maxilla, inferior nasal concha, sphenoid, and ethmoid bones, the vomer and its fellow of the opposite side. Synonym: os palatinum. (05 Mar 2000) |
