cannon bone,   a bone in the limb of hoofed animals, extending from the fetlock to the hock joint in the hind leg or the fetlock to the carpus in the foreleg; equivalent to a metacarpal or metatarsal in humans.
bones of face,   facial bones,   the bones that constitute the facial part of the skull, including the hyoid, palatine, and zygomatic bones, the mandible, and the maxilla; many authorities also include the lacrimal and nasal bones, the inferior nasal concha, and the vomer, and exclude the hyoid bone.
sesamoid bones,   numerous ovoid nodular bones, often small, usually found embedded within a tendon or joint capsule, principally in the hands and feet (ossa sesamoidea manus and ossa sesamoidea pedis, respectively); two sesamoid bones, the fabella and patella, are associated with the knee.

The IP I is a typical location of resorptive erosions which may be observed at the dorsal aspect of the first metacarpal bone subjacent to the extensor pollicis longus tendon and on the proximal phalanx at the insertions of the flexor pollicis brevis and adductor pollicis muscles.
Erosions of the triquetrum and the pisiform bones are common in early rheumatoid arthritis and occur at three sites: the proximal medial portion of the triquetrum, the distal medial portion of the triquetrum, and the adjacent surfaces of the triquetrum and the pisiform.
Plain radiographs may disclose superficial or deep erosion on the palmar surface of the triquetral bone and the dorsal surface of the pisiform bone.

 Radius (bone) -- Facts, Info, and Encyclopedia article   (Site not responding. Last check: 2007-10-21)
The radius is situated on the lateral side of the (The inner and longer of the two bones of the human forearm) ulna, which exceeds it in length and size.
Beneath the neck, on the medial side, is an eminence, the radial tuberosity; its surface is divided into a posterior, rough portion, for the insertion of the tendon of the Biceps brachii, and an anterior, smooth portion, on which a bursa is interposed between the tendon and the bone.
The articular surface for the ulna is called the ulnar notch (sigmoid cavity) of the radius; it is narrow, concave, smooth, and articulates with the head of the ulna.

 Triquetral bone - Wikipedia, the free encyclopedia
The triquetral bone (also called triquetral, os triquetrum, cuneiform bone, pyramidal bone, cubital bone, os pyramidale, os triangulare, three-cornered bone, and triangular bone) is a type of carpal bone.
The triquetral bone is located in the wrist on the medial side of the proximal row of the carpus between the lunate and pisiform bones.
It connects with the pisiform, hamate, and lunate bones.

The hamate is one of the eight carpal bones in the wrist and forms part of the carpal tunnel – through which several important tendons, nerves and blood vessels pass.
The signal from all the carpal bones is suppressed (dark) except the hamate bone which demonstrates high signal – bruising due to trauma.
