Term | Definition |
cervical vertebrae | Neck vertebrae, 1st: atlas, 2nd: axis |
thoracic vertebrae | articulate with ribs |
rib | sternum in front of ribs, costal ribs posterior, free ribs not connect in posterior |
lumbar vertebrae | posterior-thoracic |
sacral vertebrae | articulate with pelvic girdle |
caudal vertebrae | tail |
baculum | penis bone |
pectoral girdle | (forelimb) pectoral girdle (shoulder girdle), scapula shoulder blade, scapular spine, clavicle, coracoid (rudimentary and fused with scapula) |
humerus | ball-in-socket with scapula |
radius | shorter than ulna, joint with humerus=elbow |
ulna | extends farther back into joint with humerus=elbow |
carpals | wrist bones |
metacarpals | elongated and after carpals, 5 |
phalanges | extend from distal end of each metacarpal, 1st: pollex/thumb |
pelvic limb | hip girdle/ pelvic girdle |
dorsal ilia | articulated with sacral vertebrae |
ischia | directed posteriorly and forms bony part of rump |
pubic bones | project anteriorly and posteriorly and joined at distal ends, pubic symphysis: junction between pubic bones |
acetabulum | where 3 pelvic bones meet: socket with head of femur |
femur | thigh bone articulates with acetabulum |
fibula | greatly reduced compared to tibia |
tibia | more medial and larger than fibula |
knee | bends project distal segments posteriorly, patella: kneecap develops in tendon on anterior side of joint |
tarsal bones | ankle, part of hind foot (pes), calcaneum (largest, heel bone) attachment of Achilles tendon, astragalus (large and adjacent and medial to calcaneum) |
metatarsal bones | 5 elongate, part of hind foot (pes) |
phalanges | from metatarsal, pedal digits (toes): hallus (1st most medial) made of 2 phalanges, other digits 3 phalanges, part of hind foot (pes) |
Claws | keratinized epidermal cells, dorsal scale-like plate: unguis, ventral plate: subunguis (continuous with pad at end of digit) |
nail | modified claw covers only dorsal surface of end of digit |
hoof | in ungulates, pad just behind hoof: frog |
