Autonomic neuromuscular junctions

This review traces the history of the discovery and subsequent understanding of smooth muscle cells and their motor innervation. Smooth muscle tissue is made up of thousands of very small, individual, electrically connected, muscle cells. Each axon that enters a smooth muscle tissue branches extensively to form a terminal arbour that comes close to hundreds of smooth muscle cells. The branches of the terminal arbour are varicose, and each varicosity, of which there can be thousands, contains numerous transmitter storage vesicles.
