Medial epicondyle (Humerus)

This medial bulge is nearest to the trochlea

Lateral epicondyle (Humerus)

This lateral bulge is nearest the capitulum

Coronoid fossa (Humerus)

Depression on the anterior humerus mostly proximal to the trochlea

Olecranon fossa (Humerus)

Depression the the posterior humerus between the capitulum and the trochlea

Deltoid tuberosity

Anterior and lateral; very indistinct, rough area, along the anterior lateral edge of the diaphysis

Head (Radius)

The most proximal portion of the radius, which is very round and articulates with the capitulum

Radial tuberosity (Radius)

A small bulge located just a few cenitmeters distal to the head of the radius; insertion of biceps brachii

Dorsal radial tuberosity (Radius)

A bumpy area located at the distal end of the humerus on the posterior side

Styloid process (Radius)

A small pointy structure at the distal end and on the lateral side of the radius; Best landmark for anterior

Interosseous membrane (Ulna)

A fibrous sheet connets lateral margin of ulnar shaft to radius; All bones are surrounded by a connective tissue covering aclled the periosteum.

Olecranon (Ulna)

The large, rounded, posterior bulge at the proximal end of the ulna

Trochlear notch (Ulna)

Styloid process (Ulna)

A pointy process at the distal end and on the medial, posterior edge of the ulna

Capitate (Wrist)

The most cental, distal carpal bone

Hamate (Wrist)

The carpal with the "hook" and is medial to the capitate

Pisiform (Wrist)

Triquetrum (Wrist)

Posterior to the pisiform

Lunate (Wrist)

Metacarpals (Hand and Digits)

Five elongated bones that make up the back of the hand. They are numbered with Roman numerals (I to V) with I starting on the thumb (pollex) side.

Digits (Hand and Digits)

Made of phalanges (singular is phalanx) Each digit has three phalanges except for the thumb. Each individual phalanx is called: proximal, middle, distal phalanx. The thumb only has a proximal and sital phalanx

Diaphysis

The shaft of the bone; compact bone cylinder; Medullary (marrow) cavity (yellow bone marrow)

Epiphysis

Wide part at each end of the bone (proximal epiphysis and distal epiphysis); Articulates with other bones; Spongy bone covered with compact bones

Metaphysis
