Anatomy of the Nutrient Arteries of Superficial Thenar Muscles / 第三军医大学学报

ABSTRACT

Thirty adult hands were dissected under dissecting microscope, and it was found that the nutrient arteries of the superficial thenar muscles arise from the nearby branches directly or indirectly from the radial artery. They take a centripetal course supplying the muscles from the periphery towards the center. Both the muscles and arteries are superficially located with abundant anastomoses between the vessels. From the morphological point of view, it is less likely that there will be ischemic contracture of the muscles if the arteries are compressed.
