| Popis: | Detailed histological and histochemical studies were made on the effect of transection on the perineural epithelium of the peripheral nerves of rat and cat. Histologically and histochemically it has been shown that the perineural epithelium does not undergo any change in the proximal as well as in distal segments of these transected nerves and is maintained as seen in the untransected nerves. These studies also show that the capsule of the muscle spindle is made up of a continuation of the perineural epithelium and maintains its histological structure, as well as its enzyme equipment. Electronmicroscopic evidences are given for the normal maintenance of this epithelium in the regenerating nerve. The only structure which does not show any change when a nerve is transected is the perineural epithelium. It has been pointed out that the perineural epithelial tube plays an important role in conducting the regenerating axons within the neurilemmal tube to the proper sensory and motor endings. |
