Flexor Digitorum Superficialis origin and insertion
origin: Medial epicondyle of humerus, coronoid process of ulna; shaft of radius; insertion: By four tendons into middle phalanges of fingers 2-5
Deep action
Action
Deep innervation
Nerve
Flexor Carpi Ulnaris origin and insertion
origin: Medial epicondyle of humerus, olecranon process, and posterior surface of ulna; insertion: Pisiform bone and base of fifth metacarpal
Flexor Digitorum Superficialis action
Flexes wrist and middle phalanges of fingers 2-5, the important finger flexor when speed and flexion against resistance are required.
Flexor Digitorum Superficialis innervation
Median nerve
Palmaris Longus origin and insertion
origin: Medial epicondyle of humerus; insertion: Palmar aponeurosis
Flexor Carpi Ulnaris action
Powerful flexor of wrist; also adducts hand in concert with extensor carpis ulnaris (posterior muscle); stabilizes wrist during finger extension
Flexor Carpi Ulnaris innervation
Ulna nerve
Flexor Carpi Radialis origin and insertion
origin: Medial epicondyle of humerus; insertion: Base of second and third metacarpals; insertion tendon easily seen and provides guide to position of radial artery (used for pulse taking) at wrist
Palmaris Longus action
Weak wrist flexor; may tense fascia of palm (palmar aponeurosis) during hand movements
Palmaris Longus innervation
Median nerve
Pronator Teres origin and insertion
origin: Medial epicondyle of humerus; coronoid process of ulna; insertion: By common tendon into lateral radius, midshaft
Flexor Carpi Radialis action
Powerful flexor of wrist; abducts hand; synergist of elbow flexion
Flexor Carpi Radialis innervation
Median nerve
Superficial origin and insertion
origin: Origin; insertion: Insertion
Pronator Teres action
Pronates forearm; weak flexor of elbow
Pronator Teres innervation
Median nerve
Brachioradialis origin and insertion
origin: Lateral supracondylar ridge at distal end of humerus; insertion: Base of styloid process of radius
Superficial action
Action
Superficial innervation
Nerve
Brachialis origin and insertion
origin: Front of distal humerus; embraces insertion of deltoid muscle; insertion: Coronoid process of ulna and capsule elbow joint
Brachioradialis action
Synergist in forearm flexion; acts to best advantage when forearm is partially flexed and semipronated; during rapid flexion and extension, acts to prevent joint separation
Brachioradialis innervation
Radial nerve
Biceps brachii origin and insertion
origin: Coracoid process (short head); Tubercle above glenoid cavity and lip of glenoid cavity (long head); Tendon of long head runs within capsule and descends into intertubercular groove of humerus; insertion: By common tendon into radial tuberosity
