"s" shaped bone, aka collarbone
articulates w/manubrium of the sternum on medial end
articulates w/acromion process of scapula on lateral end
broad, flat process at the end of the scapular spine. articulates w/clavicle
upper lateral edge. articulates w/head of the humerus (the hole for the humerus)
head of humerus
smooth, rounded end that articulates w/the glenoid cavity of the scapula to form the shoulder joint
larger projection on the proximal end of the humerus that serve as attachment sites for the muscles of the rotator cuff.
found on the proximal lateral surface of the humerus
smaller projection on the proximal end of the humerus that serve as attachment sites for the muscles of the rotator cuff.
found on the proximal ANTERIOR surface of the humerus
above the capitulum is a knob-like projection similar to the one above the trochlea
several extensor muscles of the forearm attach to this epicondyle
a rounded process on the lateral distal surface of the humerus
this process articulates w/the head of the radius
the grooved process on the medial distal surface of the humerus that articulates w/the ulna
a depression on the anterior surface of the humerus, superior to the trochlea (smaller indentation)
depression on the posterior distal surface of the humerus (larger indentation)
medial bone in the forearm when arm is in anatomical position
articulates proximally witht he trochlea of the humerus and the head of the radius and distally w/the ulnar notch of the radius
the posterior proximal end of the ulna
fits into the olecranon fossa of the humerus when the forearm is extended
on the anterior proximal end of the ulna.
fits into the coronoid fossa of the humberus when the forearm is flexed
on the lateral proximal end of the ulna
allows the head of the radius to rest against the ulna
styloid process (stylus) of ulna
a small pointed projection on the medial distal end of the ulna
this is the bump that can be palpated on the medial surface of the wrist
styloid process (stylus) of radius
pointed projection on the lateral surface of the distal end of the radius
