Manubrium
Which bone articulates with the acromial end of the clavicle?
Acromion of scapula
What does the glenoid fossa articulate with?
Head of humerus
Which muscle attaches at the supraglenoid tubercle?
Long head of biceps brachii
Which muscle attaches at the infraglenoid tubercle?
Long head of triceps brachii
Which mm attach on the coracoid process of the scapula? (Three)
1) Caracobrachialis
2) Short head of biceps brachii
3) Pectoralis Minor
Which forearm muscle group attaches at the medial epicondyle of the humerus? Lateral
epicondyle?
Flexor mm of forearm; Extensor mm of forearm
Which muscle of the upper arm attaches in the intertubercular groove?
Long head of biceps brachii
Which bones does the capitulum of the humerus articulate with?
head of the radius
Which 2 bony structures does the head of the radius articulate with?
Scaphoid and Lunate
Which bone does the trochlea of the humerus articulate with?
, Ulnar
Which bone does the ulnar notch of the radius articulate with?
Head of ulna
Which muscle of the arm attaches at the olecranon?
Triceps brachii
What is the purpose of the olecranon fossa? Is it located posterior or anterior on the
humerus?
Provides a space for the ulna to go when the arm is extended, without digging into the bone.
Located posteriorly

Head of radius
Where is the coronoid fossa located?
superior to the trochlea on the anterior surface of the distal humerus
