Appendicular Skeleton

Question 1

Humerus (13)

Answer 1

Head-attaches to glenoid fossa of scapula
Greater tubercle-anterior, opposite of head end

Pectoral ridge-passes thru shaft, spirals
Deltoid ridge-triangular bump on shaft
Shaft-body of humerus

Coronoid fossa-medial, above trochlea
Radial fossa-anterior/lateral, above capitulum
*Olecranon fossa-posterior/above trochlea
Medial epicondyle-attach ulna, above trochlea
Lateral epicondyle-attach radius, above capit.
Capitulum-smaller, artic w/ head of radius
Trochlea-bigger, attaches to ulna
