ANATOMICAL NECK
greater and lesser tubercles; site of muscle attachments
INTERTUBERCULAR SULCUS
distal to the tubercles
SURGICAL NECK
larges fleshly deltoid muscle attaches
DISTAL TUBEROSITY
radial nerve
RADIAL GROOVE
(medial)distal end, looks somewhat like a spool
TROCHLEA
(lateral)ball-like; with the trochlea articulates with the FA
CAPITULUM
above trochlea, anteriorly

MEDIAL AND LATERAL EPICONDYLES
radius and ulna
FOREARM
lateral, thumb side
RADIUS
distal end crosses over and ends up medial to the ulna when hand faces backwards
RADIUS
distal end; connected to ulna via interosseous membrane
STYLOID PROCESS
disc-shaped head of the radius forms a joint with the capitulum
STYLOID PROCESS
where the tendon of the biceps muscles attaches
RADIAL TUBEROSITY
medial bone
ULNA
The inferior margin of the trochlear notch is formed by a prominent lip of bone called the
CORONOID PROCESS (of the ulna)
Projecting from the posterior side of the ulnar head is the
STYLOID PROCESS (of the ulna)
The posterior and superior portions of the proximal ulna make up the ____, which forms the bony tip of the elbow.
