ant arm and cubital fossa Flashcards
how to test biceps brachii muscle
elbow jt is flexed against resistence when forarm is supinated
path of musculocutaneous n and what does it turn into
pierces thru coracobrchialis and descends down lat side of arm
ant to lat epicondyle is pierces brachial fascia continuing as the lat cutaneous nerve of forearm
what deficit would u have if musculocutaneous nerve was impinged in caracobrachialis
motor and sensory deficits
if after just sensory deficits
in the cubital fossa where is the median nerve located in relation to the brachial artery
medial
prox in arm it is lat tho
in case of bleeding where do u compress the brachial artery
med to humererus near middle of arm
path of ulnar nerve
present in prox half of ant arm, goes into post arm thru IM septum and reenters inf to medial epicondykle
where does the medial cutaneous nerve of arm supply
supplies skin of anteriomedial arm as low as medial epicondyle
a positibe biceps tendon reflex confirms integrity of what nerve (lvls)
musculocutaneous + apr c5,6,7
what happens in a long head biceps rupture
rupture from supraglenoid tubercle
- poping sensation and an abnormal buldge in distal part of ant arm
- result of wear, repatative overhead motions
what vein is made when basilic and cephalic vein join in cubital fossa
median cubital vein (v shaped appearence)
what nerve is fused to periosteum and not actually in the cubital fossa
Ulnar nerve
sup, med and lat borders of cubital fossa
sup- imaginary line bw med and lat humoral epicondyles
med- pronator teres +common flexxor tendon
lat- brachioradialis, common extensor tendon
floor and roof of cubital foss
floor- brachialis, supinator
roof- Bicipital apponeurosus, med + lat cutaneous n, bascilic, cephalic, median cubital, antibrachial v
contents of cubital foss med to lat (5)
- median n
- brachial a and its bifurcation
- deep v of accompaning a
- biceps brachii tendon
- radial n
