Surgical neck
a rough prominence on the anterolateral surface of the humerus
Deltoid tubercle
small rounded prominence forming the lateral part of the lower articular end of the humerus
Capitulum (little head)
forms the medial part of the distal articular surface of the humerus
Troclea (pulley)
a depression on front of the lower humerus immediately above the trochlea
Coronoid fossa
a small depression on the front of the lower humerus above the capitulum
Radial fossa
a depression on the back of the lower humerus above the trochlea
Olecranon fossa
a depression on the back of the lower humerus above the trochlea
Olecranon fossa
knucklelike rounded bony prominence on the lateral margin of the lower humerus above the capitulum
Medial epicondyle
smaller bony prominence on the lateral margin of the lower humerus
Lateral epicondyle
is a furrow on the dorsal surface of the medial epicondyle through which the ulnar nerve descends the forearm
Ulnar groove
type of bone-Radius
long bone
lateral bone of the forearm
Radius
the head of the radius is its upper expanded disclike end, with slightly concave upper articular surface
Radius
a rough prominence on the anteromedial surface of the radius below its neck
Radial tuberosity
a large bony prominence on the lateral border and distal end of the radius
Styloid process
a small depression on the medial margin of the distal end of the radius above its articular surface
Ulnar notch
narrower in the proximal but as it goes distally it becomes wider
Radius
a large smooth area on the distal end of the radius that articulates with the carpal bones
Carpal articular surface
type of bone-Ulna
long bone
wider in the proximal portion but narrower in the distal portion
Ulna
medial bone of the forearm
Ulna
bluntly rounded upper end of the ulna that lies posterior to the elbow joint
Olecranon process
extends anteriorly from the upper part of the body of ulna. It is beaklike and lies below and anterior to the olecranon
Coronoid process
concave half-moon shaped hollow on the anterior surface of the olecranon and the upper curved surface of the coronoid process

capitulum of the humerus and head of radius
Humeroradial
a hinge joint
Elbow joint (Cubital joint)
formed anterior to the wrist by a transverse carpal ligament that is attached to the scaphoid and trapezium laterally and to the pisiform and hook of the hamate medially
Carpal Tunnel
this ligament, together with the anterior curved surfaces of the carpal bones, forms a tunnel for the tendons, blood vessels and nerves pass from the forearm into the hand
Carpal Tunnel
one or both arms may be absent
Abrachium
a joining together of the upper ends of the radius and ulna, with inability to supinate or pronate to the hand
Fusion
mimics the density of the bone. They are not bones; they are calcium deposits
