|
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
|
