wrist muscles Flashcards
what muscle is this
flexor carpi radialis
what muscles is this
flexor carpi ulnas
where do flexor carpi radials and ulnas arise from
medial epicondyle from common flexor tendon arise radial and ulnar sides of wrist
ulnar nerve passes through these two heads
flexor carpi radialis insertion
inserts base second metacarpal
flexor carpi ulnas insertion
pisiform bone
transmits force to hamate
[pisohamate, pisometacarpal ligament]
what movement do flexor carpi radialis and ulnas produce
flexion wrist
separate - ulnar and radial abduction
what is this muscle
palmarus longus
insertion palmar is longs
most superficial into palmar fascia
role palmarus longs
flexion wrist
label the extensors of the wrist
extensor carpi radialis longus
lateral epiccondylar ridge
common extensor tendon
extensor radialis brevis
lateral epicondyle
common extensor tendon
where do extensors pass under
extensor reticularum
acts as a pulley
radialis longus brevis top
ulnas bottom
identify all the veins in this picture
what does the basilica vein join onto
brachial vein - splits joins onto brachial - axillary vein
what nerve is this
musculocutaneous
what nerve is this
median nerve
what nerve is this
ulnar
what nerve is this
radial
what does the musculocutaneous nerve supply
shoulder flexors
coracobrachialis
what is the course of the musculocutaneous nerve
through coracobrachialis, emerges dee to bicep runs down arm between biceps and brachial emerges to become lat cutaneous n forearm
identify median and ulnar
what is the course median nerve
diverges from ulnar nerve follows course brachial a, at elbow lies medial to the artery goes between brachial tendon and pronator teres, passes between two head pronator trees
what is the course ulnar nerve
runs medial to triceps tendon and behind medial epicondyle pass between two head flexor carpi ulnas
what muscles does median nerve supply
pronator teres, flexor carpi radialis, palmares longus, pronator quadratus
what muscles does ulnar n supply
flexor carpi ulnas
what is the course of the radial erve
passes round humorous runs between medial and lateral heads triceps, emerges above brachioradialis to lateral epicondyle dividing into deep motor and superficial sensory branch
what muscles does radial n supply
triceps, brachioradialis, ancones, all three wrist extensors and supinator
