Radial artery
-
-
It descends along the medio-volar border of the radius under the flexor carpi radialis, passes down subcutaneously over the posterior aspect of the carpus under the deep fascia but out side the carpal canal and is continued down as the medial deep volar metacarpal artery.
-
This radial artery gives branches to the formation of the rete carpi dorsale and volare and another branch, which passes between the suspensory ligament and the large metacarpal bone.
-
This branch gives off the middle deep volar metacarpal artery and then passes through the foramen at the proximal part of the groove to anastomose with the dorsal metacarpal artery.
