| cranial bones | The paired inferior nasal concha, lacrimal, maxilla, nasal, palatine, parietal, temporal, and zygomatic; and the unpaired ethmoid, frontal, occipital, sphenoid, and vomer. Synonym: ossa cranii, cranial bones. (05 Mar 2000) |
| heterotopic bones | Bone's that do not belong to the main skeleton but that regularly develop in certain organs, e.g., the heart, penis, clitoris, and snout of some animals. (05 Mar 2000) |
| scroll bones | See: inferior nasal concha, middle nasal concha, superior nasal concha, supreme nasal concha. (05 Mar 2000) |
| sphenoidal turbinated bones | Paired ossicles of pyramidal shape, the spines of which are in contact with the medial pterygoid lamina, the bases forming the roof of the nasal cavity. Synonym: conchae sphenoidales, Bertin's bones, Bertin's ossicles, sphenoidal turbinated bones. (05 Mar 2000) |
| sutural bones | Small irregular bones found along the sutures of the cranium, particularly related to the parietal bone. Synonym: ossa suturarum, Andernach's ossicles, epactal bones, epactal ossicles, wormian bones. (05 Mar 2000) |
| tarsal bones | The seven bones which form the tarsus - namely, calcaneus, talus, cuboid, navicular, and first, second and third cuneiforms. The tarsus is a skeletal part of the foot. (12 Dec 1998) |
| ear bones | The small bones of the middle ear; they are articulated to form a chain for the transmission of sound from the tympanic membrane to the oval window. Synonym: ossicula auditus, ear bones, ossicular chain. (05 Mar 2000) |
| epactal bones | Small irregular bones found along the sutures of the cranium, particularly related to the parietal bone. Synonym: ossa suturarum, Andernach's ossicles, epactal bones, epactal ossicles, wormian bones. (05 Mar 2000) |
| turbinated bones | See: inferior nasal concha, middle nasal concha, superior nasal concha, supreme nasal concha. (05 Mar 2000) |
| joints of ear bones | The joints of the ossicular chain consisting of incudomallear joint, incudostapedeal joint, and the tympanostapedeal syndesmosis. Synonym: articulationes ossiculorum auditus, joints of ear bones. (05 Mar 2000) |
| facial bones | The facial skeleton, consisting of bones situated between the cranial base and the mandibular region. While some consider the facial bones to comprise the hyoid, palatine, and zygomatic bones, mandible, and maxilla, others include also the lacrimal and nasal bones, inferior nasal concha, and vomer but exclude the hyoid bone. (12 Dec 1998) |
| foot bones | The bones of the distal portion of the leg in man and animal. In the human, it consists of the tarsal bones, the metatarsal bones, the phalanges (toes), and the tissues encompassing them. (12 Dec 1998) |
| leg bones | The bones of the lower extremity in man and of any of the four extremities in animals. (12 Dec 1998) |
| basal skull fracture | <orthopaedics> A fracture involving the base of the cranium. This fracture is often difficult to detect clinically. Findings may include raccoon eyes, Battle's sign, haemotympanum and cerebrospinal fluid rhinorrhoea. Plain skull X-ray will often not reveal the basal skull fracture, making a CT scan or MRI the most reliable diagnostic investigation. (15 Nov 1997) |
