Abstract
The gastrocnemius muscles of turtles (Testudo horsfieldi) were completely detached and reimplanted in the same position with the nerve led up to the graft or with denervation. The recovery of contractile activity and innervation of the grafts from the approximated nerve were studied from their beginning 1 month after the operation until their still incomplete state 6 months after the operation. The grafts had a muscular type of structure only if their innervation was restored; otherwise, connective tissue developed in them. Two months after the operation a significant difference was found in the weight of the innervated and denervated grafts. As regards the time for recovery of innervation and of the gravimetric indices, grafts in turtles occupy an intermediate position between those studied previously in rats and frogs.
