Table of muscles of the human body/Intro
Contents
Vertebral column
Thoracic walls
Muscle | Origin | Insertion | Artery | Nerve | Action | Antagonist |
---|---|---|---|---|---|---|
pectoralis major | anterior surface of the medial half of the clavicle
Sternocostal head: anterior surface of the sternum, the superior six costal cartilages |
intertubercular groove of the humerus | pectoral branch of the thoracoacromial trunk | lateral pectoral nerve and medial pectoral nerve | Adducts and medially rotates the humerus. It also draws the scapula anteriorly and inferiorly.
Clavicular head: flexes the humerus | |
pectoralis minor | 3rd to 5th ribs, near their costal cartilages | medial border and superior surface of the coracoid process of the scapula | pectoral branch of the thoracoacromial trunk | Medial pectoral nerves (C8, T1) | stabilizes the scapula by drawing it inferiorly and anteriorly against the thoracic wall | |
subclavius | first rib | subclavian groove of clavicle | thoracoacromial artery, clavicular branch | nerve to subclavius | depression of clavicle | |
serratus anterior | fleshy slips from the outer surface of upper 8 or 9 ribs | costal aspect of medial margin of the scapula | lateral thoracic artery (upper part), thoracodorsal artery (lower part) | long thoracic nerve (from roots of brachial plexus C5, C6, C7) | protract and stabilize scapula, assists in upward rotation | rhomboid major, rhomboid minor, trapezius |
Shoulder
Arm
Anterior compartment
Muscle | Origin | Insertion | Artery | Nerve | Action | Antagonist |
---|---|---|---|---|---|---|
coracobrachialis | coracoid process of scapula | medial humerus | brachial artery | musculocutaneous nerve | flexes humerus | |
biceps brachii | short head: coracoid process of the scapula. long head: supraglenoid tubercle | radial tuberosity | brachial artery | Musculocutaneous nerve (Lateral cord: C5, C6, C7) | flexes elbow and supinates forearm | Triceps brachii muscle |
brachialis | anterior surface of the humerus, particularly the distal half of this bone | coronoid process and the tuberosity of the ulna | radial recurrent artery | musculocutaneous nerve | flexion at elbow joint |
Posterior compartment
Muscle | Origin | Insertion | Artery | Nerve | Action | Antagonist |
---|---|---|---|---|---|---|
triceps brachii | long head: scapula lateral head: posterior humerus medial head: posterior humerus |
olecranon process of ulna | Profunda brachii | radial nerve | extends forearm, caput longum adducts shoulder | Biceps brachii muscle |
anconeus | Lateral epicondyle of the humerus | lateral surface of the olecranon process and the superior part of the posterior ulna | Profunda brachii, recurrent interosseous artery | radial nerve (C7, C8, and T1) | partly blended in with the triceps, which it assists in extension of the forearm. Stabilises the elbow and abducts the ulna during pronation. |

pronator quadratus | medial, anterior surface of the ulna | lateral, anterior surface of the radius | anterior interosseous artery | median nerve (anterior interosseous nerve) | pronates the forearm | Supinator muscle |
flexor digitorum profundus | ulna | distal phalanges | anterior interosseous artery | median (anterior interosseous), muscular branches of ulnar | flex hand, interphalangeal joints | Extensor digitorum muscle |
flexor pollicis longus | The middle 2/4 of the Template:Disambiguation needed surface of the radius and the adjacent interosseus membrane. (Also occasionally a small origin slightly on the medial epicondyle of the ulna.) | The base of the distal phalanx of the thumb | Anterior interosseous artery | Anterior interosseous nerve (branch of median nerve) (C8, T1) | Flexion of the thumb | Extensor pollicis longus muscle, Extensor pollicis brevis muscle |

abductor minimi digiti | pisiform | base of the proximal phalanx of the 5th digit on the ulnar or medial side | ulnar artery | deep branch of ulnar nerve | Abduction of little finger | |
flexor digiti minimi brevis | hamate bone | little finger | ulnar artery | deep branch of ulnar nerve | flexes little finger | extensor digiti minimi muscle |
opponens digiti minimi | Hook of hamate and flexor retinaculum | Medial border of 5th metacarpal | ulnar artery | deep branch of ulnar nerve (C8 and T1) | Draws 5th metacarpal anteriorly and rotates it, bringing little finger (5th digit) into opposition with thumb |
