**

A

Superfical Arch - ulnar and radial arteries

23
Q

Sensory Innervation - palm

**

A

Median nerve to palm - superfical branch

24
Q

Boundaries of snuffbox

***

A

(Lateral) Abductor Polliccis Longus/Extensor Pollicis Brevis
(Medial) Extensor Pollicis Longus
(Floor) Schaphoid and Trapezium
distal tendons of extensor carpi radialis longus and brevis
(Bottom) Extensor Retinaculum

25
Q

Structures of snuffbox, clinical significance

***

A

Radial Artery
Scaphoid fracture = radial artery compressed
NO blood supply to bone = degeneration

26
Q

significance of extensor hood

***

A

Tendons of ED and EPL pass to dorsal hand and expand over phalanges
Intrinsic have muscles insert to allow fine movements

27
Q

Lateral Epicondylitis - affected muscles and movements

***

A

Inflammation and pain at tendons of Lateral epicondyle, Tennis elbow
Affects muscles of posterior arm - specifically extensor carpi radialis brevis
Affects wrist extension, gfip strength

28
Q

Carpal Tunnel Syndrome - symptoms

***

A

Pain,weakness, numbeness in fingers, including thumb but not including palm or little finger due to compression of median nerve in carpal tunnel

29
