Anatomy of Carpal Tunnel and Vasculature of Upper Limb Flashcards
what is the carpal tunnel
an osteofascial tunnel between the carpal bones and the inextensible flexor retinaculum(palmar ligament)
what nerve travels through the carpal tunnel and what does this present risk of
median nerve
presents risk or nerve compression if narrowing of space in tunnel
what is the carpal tunnel formed by
flexor retinaculum and carpal bones
what is the contents of the carpal tunnel
flexor digitorum superficialis(x4), flexor digitorum profundus(x1), flexor pollicis longus(x1) and the median nerve
what are the 3 most proximal arteries of the upper limb, in order of most proximal to least
subclavian, axillary and brachial arteries
what are the 4 most distal arteries of the upper limb
radial and ulnar arteries, and the deep and superficial palmar arches
what arteries are found in the forearm
radial and ulnar arteries
what arteries are found in the hand
superficial and deep palmar arches
what is the contents of the scapular anastamoses, that supplies the scapula region
suprascapular artery, dorsal scapular artery, circumflex scapular artery
describe the venous drainage of the upper limb
veins generally follow arteries but venous drainage is highly variable from person to person
what are the venae comitantes
this is the name given to the veins, often a pair of veins, that are on either side of and accompany the brachial artery
what is the lateral and medial veins of the upper limb
medial = basilic lateral = cephalic
what are the 2 most proximal veins of the upper limb called, in order of most proximal to least
subclavian vein and axillary vein
what vein connects the cephalic and basilic veins in the upper limb
the median cubital vein
