Question 1

Path of radial artery in hand?

Answer 1

Superficial: through Thenar –> contributes to arch (under aponeurosis, ontop of flex tendons)- supplying digits, just like nerve supply
Deep branch:(radial artery) Behind thumb –> between 2x head of dorsal interossei and b/w 2x heads of adductor pollicis

Question 2

Path of ulnar artery in hand?

Answer 2

Superficial: anastomoses with Radial arety
Deep: Hypothenar muscle mass –> ontop of MC, deep to flexor tendons

Question 3

What forms the Superficial Palmar arteries?

Answer 3

Radial and Ulna nerve anastomosing

Question 4

What branches off the superficial palmar arteries?

Answer 4

CPDA
Common palmar digital arteries
run between MC and approach creases
–> then Proper palmar digital arteries, supplying 1/2 finger each

Question 5

What branches off the deep palmar arteries?

Answer 5

PMCA
Palmar Metacarpal Arteries
anastomose with Common palmar digital arteries (CPDA)
