31. Summary of Muscles

32. Anterior Arm
Biceps Brachii
Origin Short head: tip of coracoid
process of scapula; Long head:
supraglenoid tubercle of
scapula
Insertion Tuberosity of radius and fascia
of forearm via bicipital
aponeurosis
Action Supinates and flexes forearm
Nerve Supply Musculocutaneous nerve (C5
and C6)
Blood Supply Muscular branches of brachial
artery

33. Anterior Arm
Brachialis
Origin Distal half of anterior surface
of humerus
Insertion Coronoid process and
tuberosity of ulna
Action Flexes forearm and elbow joint
in all positions
Nerve Supply Musculocutaneous nerve (C5,
C6) Radial Nerve (C5, C6)
Blood Supply Muscular branches of brachial
artery, recurrent radial artery

34. Anterior Arm
Coracobrachialis
Origin Tip of coracoid process of
scapula
Insertion Upper half of medial surface of
humerus
Action Flexes and adducts arm
Nerve Supply Musculocutaneous nerve (C5,
C6)
Blood Supply Muscular branches of brachial
artery
