【Abstract】 Measurement of the length of the muscular branches of the nerves in the lower extremity was made on 40 dissection-room specimens.The muscular branches of sciatic nerve and of its two major divisions were measured according to Sunderland’s method. For the femoral nerve,we chose the interspinous line as the fixed point.The results were as follows: A muscle may be innervated by a single or several branches.In most cases,the popliteus was supplied by a single branch,the extensors of the thigh were usually sup- plied by many branches.In each muscle group,the number of the muscular branches to one or two muscles was always larger than that to the others.The largest and most powerful muscle (or muscles) received most nerve supply. The order of origin of the muscular branches to a muscle in each muscle group was usually fixed.The muscle of high origin received earlier branch from the trunk.The muscle of superficial position seemed to enjoy the similar previlege as that of higher origin.Thus in the anterior muscle group of the thigh,the branch to the sartorius came out first,branch to the rectus femoris the next,then followed by that of the vastus inter- medius the vastus lateralis and the vastus medialis;This order corresponds to the se- quence generation of the peripheral nerves after injury.更多还原
