Similarities
Differences
Pectoral Girdle
• Clavicle – collarbone
– Anterior attachment (?)
– Posterior attachment (?)
• Scapula – shoulder blades
– Posterior attachment (?)
– Spine – divides posterior surface into 2
sections
– Coracoid process (“Corac” = ?) – curves
to clavicle
– Acromion process – forms tip of shoulder
– Glenoid cavity (or fossa) – depression that
articulates with head of humerus

Humerus
•
•
•
•
Head fits into glenoid cavity of scapula
Greater tubercle – lateral process
Lesser tubercle – more anterior process
Intertubercular groove – narrow furrow
“between tubercles”
• Deltoid tuberosity – v-shaped, rough area
where _________ muscles attach to humerus
• Olecranon fossa – posterior depression that
receives an ulnar process when elbow is
straightened
• Coronoid fossa – anterior depression that
receives a radial process when elbow is bent
Radius
• Shorter bone of lower arm
• Located on thumb side of arm
• Disc-like head articulates with humeru
and with radial notch of the ulna (so
your arm can rotate)
• Radial tuberosity, a process below the
head, provides attachment for biceps
• Styloid process – at distal end;
attachment for wrist ligaments
Ulna
• Longer than radius
• Overlaps distal end of humerus
posteriorly
• Proximal end has a wrenchlike opening
called the trochlear notch (articulates
w/humerus)
– Oleacronon process – top process
– Coronoid process – bottom process
– Radial notch – just below trochlear notch
• Head – at distal end; articulates with
ulnar notch of radius
• Styloid process – attachment for wrist
