SLIDE 65 - MOTOR END PLATES
These are the axonal effector endings which induce contraction of skeletal muscle. The gold chloride preparation stains axons black; muscle cells are long, parallel structures and reddish or purple in color; note their cross-striations.
At low magnification find a good group of axons arriving in the area and separating to innervate muscle fibers 1:1. With higher magnification look at some highly branched axon terminals (endplates) at the surface of the muscle.
