ANT415H5 Lecture Notes - Lecture 3: Olecranon Fossa, Trochlear Notch, Lesser Tubercle
Document Summary
Scapula the glenoid fossa (articulates with humerus) spine shape and acromion process and glenoid fossa can help id what species. Humerus the proximal head is identifiable by roundness + tuberosity: distal end has pully shaped articulation with the ulna in the fossa, note: head, greater tubercle, lesser tubercle, olecranon fossa. Manus/foot: metacarpals/medapodial, for small mammals you will need to identify a metacarpal as a medapodial for the lab test. You will be expected to differen- tiate between metacarpals and metatarsals for the ungulates: phalanges reduction in number of digits, may have keratinized sheath over the claw. Hindlimb femur: groove at distal for patella, note: patellar groove, head, greater trochanter. Patella fibula tibia: crest at proximal side, note: medial malleolus tarsals, ankle, note calcaneus, stragalus/talus talus may be s-shaped, dense so survives well. Pelvic girdle ilium and ischium: 2 innominate bones fused.
