Name the three muscles of anterior compartment of forearm and arm with its origin and Insertion

The anterior compartment of Arm contains 3 muscles:

1. the biceps brachii.
Origin: Short head: coracoid process of the scapula.


Long head: supraglenoid tubercle.
Insertion: Radial tuberosity and bicipital aponeurosis into deep fascia on medial part of forearm.

2. the brachialis
Origin: anterior surface of the humerus, particularly the distal half of this bone.
Insertion:coronoid process and the tuberosity of the ulna.


3. the coracobrachialis.
Origin: Coracoid process of scapula
Insertion: Anteromedial surface of humerus distal to crest of lesser tubercle









Three muscles of Anterior compartment (Forearm):


1. flexor carpi radialis
Origin :medial epicondyle of humerus (common flexor tendon)
Insertion :Bases of second and third metacarpal bones


2. Flexor carpi ulnaris muscle
Origin
Medial epicondyle (common flexor tendon) and medial margin on olecranon of ulna
Insertion
Pisiform, hook of the hamate, base of the fifth metacarpal bone


3. Flexor digitorum superficialis


Origin :medial epicondyle of the humerus (common flexor tendon) as well as parts of the radius and ulna.


Insertion :anterior margins on the base of the middle phalanges of the four fingers
