41
what is in the anatomical snuff box
tendons: extensor pollicis brevis and abductor pollicis longus bones deep in snuff box: trapezium/scaphoid (bad blood supply) radial a. runs deep inflammation: dequervians tenosynovitis (inflammation of the synovial sheaths that holds the tendon)
42
1st CMC joint
saddle joint flex/ext-trapezium is convex abd/add- trapezium is concave opposition- initial abduction followed by medial rotation other CMC joints- plane joints (glide/slide)
43
abductor pollicis longus
int mem to base of 1st abd @ CMC
44

scaphoid/trap to base of proximal phalanx CMC abduct
45
extensor pollicus longus
int mem to base of distal phalanx ext @ WRIST/MCP/IP CMC ABD (line of pull)
46

48
adductor pollicis brevis (thenar)
transverse- 3rd MC oblique- capitate + MC 2+3 CMC ADD MCP FLEX CC) ape hand (median nerve injury, only thenar muscle innervated by ulnar nerve)
49
flexor pollicis brevis
superficial (flexor retinaculum) deep (cap+trap) DEEP HEAD IS INNERVATED BY ULNAR NERVE CMC flex
50
opponens pollicis
