in the connective tissue between the muscle bundles, the peri- 

 mysial plexus, from the branches of which a fine plexus is dis- 

 tributed to the endomysium. The terminal branches end in re- 

 lation with the surface of the muscle fibres. 



The blood vessels are similarly supplied, minute ganglia occur- 

 ring here and there in the adventitia or adjacent connective tis- 

 sue. Erom these ganglia sensory branches are distributed to the 

 adventitia and intima and motor branches to the tunica media. 

 Naked nerve fibrils can be traced to the smallest blood vessels, and 

 even in the capillaries terminal fibrillae are found in relation with 

 the endothelial wall.
