Sprouting in intact sartorius muscles of the frog following contralateral axotomy.
The intact hind limb sartorius muscle of the frog was examined anatomically for sprouting following axotomy of the sciatic nerve that contains motor axons innervating the contralateral sartorius muscle. The incidence of sprouting in intact muscles of experimental animals increased more than 3-fold over normal. Thus, contralateral axotomy produces sprouting in intact sartorius muscles much the same as it does in cutaneous-pectoris and piriformis muscles of the frog.
