phalanges

finger bones

radius

forearm bones

metacarpals

heads of these bones form the knuckles

olecranon fossa

posterior depression on the distal humerus

medial epicondyle

small bump often called the "funny bone"

radial notch

Coronoid Fossa

Anterior depression, superior to the Trochlea, which receives part of the ulna when the forearm is flexed

Humerus

Arm bone

Glenoid Cavity

Depression in the scapula that articulates with the humerus

Trochlea

Distal condyle of the humerus that articulates with the ulna

Ulna

Medial bone of forearm in anatomical position

Caracoid Process

Process above the Glenoid cavity that permits muscle attachment

Deltoid tuberousity

Raises area in lateral surface of humerus to which deltoid muscle attaches

Capitulum

Rounded knob on the humerus; adjoins the radius

Acromion

Scapular region to which the clavicle connects

Clavicle

Should girdle bone that transmits forces from the upper limb to the bony thorax

Scapula
