MSK anatomy Flashcards
what runs though teh cubital fossa?
tendon of biceps, median nerve and brachial artery and superficail veins
what make up teh boarder of the cubital fossa?
line drawn between the epicondryles, brachioradialus, pronator teres
what are the bones of teh wrist?
scaphoid lunate Triquetrum. Trapezoid. Trapezium. Capitate. Hamate. Pisiform
whar is are the muscles in the forarm - superiour
pronator teres, flexor carpi radialus, palmaris longus, flexor carpi ulnaris
whar is are the muscles in the forarm - middle
: flexor digitori superialus
whar is are the muscles in the forarm - deep
• Deep: flexor digitori profundus, flexor pollicis longus, pronator quadratus
what are all of teh superficail muscles of teh wrist attatched to?
medial epicondyle - the commen flexour origin
what muscles in teh forarm are NOT inovated by teh median nerve
flexor carpi ulnaris and teh medial half of flexor digitori profundus - they are both inorvated by the ulnar nerve
whihc nerve are most of teh muscles of teh forarm inorvated by
MEDIAN
what does protraction of teh scapula look like
pushing open a door
how much doe steh scapula roate when teh ar, is raised
When you rainse the arm for every 2 degrees that the shoulder adsuctsm the scapula rotaes 1 degree
what are teh two superfical muscels on teh pectoral girdle
• Two uperficia muscels on the posteiro pectoral girde - trapezius and latissimus dorsi
what s teh pectoral girdle
teh scapula and teh clavile
where does latisumus dorsi attatch to
the humeroubs - not teh actual pectoral girdle
whihc 6 muscels help to stabalise teh shoulder
Deltoid, supraspinatus, infraspinatus, subscapularis and teres minor and major
what muscels make up teh roatator cuff and what does it do
• Supra spiaous infra spinatus, subscapularis and teres minor and called the rotatr cuff whuch are the mots important fr stabalising the joint
what does teh deltoid muscle do
• The deltoid is a poerfuk abductor of the sholder but cannot do it alone and requies other muscles to do the first 20 degress of abduction
It is innovated by the axillary nerve
• Supra sinatous doe sthe first 20 degress of abduction and then deltoid does the rest
what are the boarder of teh quadrilateral space and what runs though it
• The quadrilateral space is a small gap in the muscles formed by the teres minor, humerous, teres major and the triceps the axillery nerve runs through this to innorvate the deltiod and teres minor
what nerve are teh tricpes inorvated by
the radial nerve
what nerve are teh tricpes inorvated by
the radial nerve
what nerve are teh tricpes inorvated by
the radial nerve
what nerve are teh tricpes inorvated by
the radial nerve
what nerve are teh tricpes inorvated by
the radial nerve
what nerve are teh tricpes inorvated by
the radial nerve
