palm of hand Flashcards
palmar aponeruosis
distal attachment of palmaris longs
covers central compartment of hand
palmaris longus attachments
medial epicondyle of humorous
inserts into palmar aponeurosis
palmaris longus innervation
median nerve c7-8
palmaris longus actions
tighten palmar aponeurosis at wrist
weakly flex arm at elbow
thenar emminience
what is it madeof
-what do these look like
muscular swelling at base of thumb
flexor policis brevis-most medial-mostly under flexor pollicis brevis
abductor policis brevis-fattest,most superior, 2nd most medial
opponens pollicis-inferior to abductor pollicis longus and most lateral
hypothenar eminence
muscular swlling at base of pinky
abductor digiti minimi-most medial
flexor digititi minimi previs-more lateral to abductor digiti minmi
palmaris brevis-largest-more superficial than other two
Ulnar nerve and artery
position to each other
where do they pass
nerve is medial to artery
pass lateral to pisiform bone
superficial palmar arterial arch
distal branch of ulnar artery
terminal division of ulnar nerve
deep -motor
suerficial-sensory
whats under flexor retinaculum
-what happens if you continue on path
carpal tunnel
9 tendons and median nerve
median nerve becomes recurrent branch when enters thenar muscles
FDS tendon and FDP tendon releationship
FDS splits and attaches to sides of second phalanx to allow FDP tendon to reach distal phalanx
flexor digitorum superficialis attachments
humorous head-medial epicondyle
ulnar head-coronoid process
both-insert into sides of middle phalanges of 2nd to 5th digits
flexor digitorum superficialis innervation
median nerve c8-t1
flexor digitorum superficialis actions
flex hand at wrist
flex 2nd to 5th digits at MCP and PIP joints
weakly flex forarm at elbow
flexor digitorum profundus attachments
two thirds of flexor surface of ulna and from interosseous membrane
inserts into palmar surface of distal phalanges of 2nd to 5th digits
