Anterior Arm And Forearm Muscles Flashcards
What are the muscles of the anterior arm
Brachialis, Coracobrachialis, Biceps brachii
Biceps brachii has 2 parts of
Long and short head
Biceps brachii long head origin is
Supraglenoid tubercle of scapula
Biceps brachii short head origin is
Coracoid process
Biceps brachii insertion is
Radial tuberosity and fascia of bicipital aponeurosis
Biceps brachii action of
Flexion of elbow, supination of forearm
Biceps brachii short head action also
Resists shoulder dislocation
Biceps brachii innervation
Musculocutaneous n (C5C6
Biceps brachii vasculature
Brachial artery
Coracobrachialis origin
Coracoid process
Coracobrachialis insertion
Middle 1/3 of medial shaft of humerus
Coracobrachialis action
Helps flex and adductor arm. Resist shoulder dislocation
Coracobrachialis innervation
Musculocutaneous nerve C5C6
Coracobrachialis vasculature
Brachial artery
Brachialis origin
Distal 1/2 of anterior humerus
Brachialis insertion
Coronoid process and ulnar tuberosity
Brachialis action
Strongest flexor of elbow
Brachialis innervation (2)
Musculocutaneous nerve C5C6 and radial nerve C5C7
Brachialis vasculature
Brachial artery
Muscles of the anterior forearm superficial layer are
(PFPF) pronator Teres, flexor carpi radialis, palmaris longus, flexor carpi ulnaris
Pronator Teres origin
Ulnar: coronoid process
Humeral: medial epicondyle of humerus
Pronator Teres insertion
Lateral surface of radius
Pronator Teres action
Pronates and flexes forearm
Pronator Teres innervation
Median nerve C6C7
