Motor end plate
From Freepedia
A motor end plate is the distal (farthest from the nerve body) end of the nerve where the nerve impulse causes emission of acetylcholine molecules into the synaptic cleft to innervate muscle fibers triggering muscle contraction. A motor (efferent) nerve axon loses its myelin sheath and branches into multiple endings, which occupy depressions in the sarcolemma. Motor neurons can innervate from one to over 100 muscle fibers.
