Painful lower limb on walking longer distance
The femoral artery is the chief blood supply into the legs.
The lower limb. It and its branches supply the whole leg and foot.
The axillary artery is a major artery of the upper limb. It continues from the subclavian artery.
This comes from my A&P lab manual... "In the armpit, the subclavian artery becomes the axillary artery, which serves the upper limb." The previous answer was "brachial," which could also be a correct answer. "The brachial artery divides into the radial and ulnar arteries, which follow the same-named bones to supply the forearm and hand."
Medial aspect of the lower limb
The muscle is, Lattisimus dorsi, connected with upper limb at the bicipital groove and with lower limb at illiac crest.
