Abstract: The innervation of rat skeletal muscle, profound fascia, intermuscular connective tissue and joint capsules were studied by means of histochemi- cal techniques for the separate and consecutive demonstration of choline- sterase(ChE)and catecholamine fluorescence. Both the adrenergic or cholinergic nerves surrounding the resistance vessels of these tissues. All these vessels were showed dual innervation. It has been known that sympathetic cholinergic system innervated the arteries of skeletal muscle only. In our experiment of stretched preparation of skeletal muscle and subcutaneous or profound fascia, the sympathetic cholinergic nerve termi nals were also accompanied with the same arteriole supplying both skele- tal muscle and subcutaneous or profound fascia. As iso-OMPA was not added in ChE incubated medium, ChE-positive nerves and their axonal terminals, i. e. free nerve endings, were ob- served in skeletal muscle, profound fascia, intermuscular connective tis- sues and joint capsule. A lot of free nerve endings are present in these tissues, especially in skeletal muscle. The significance of the presence nature of these free nerve endings in the afferent nerve conduction of muscle was discussed.
