These slides have been available as demonstrations in the laboratory. Review the descriptions of these tissues on your histology sheet, especially the spinal cord. Available here are just three micrographs. The are:
MOTOR END PLATE
Skeletal muscles (C) are stimulated by nerve impulses carried by motor neurons. An axon (A) that carries the impulse away from the nerve body ends in little pads on muscle fibers called motor end plates (B).
"A" marks the central canal. "B" is the anterior medial fissure. The posterior medial sulcus is not seen in this preparation. C is the posterior horn composed of axons of the sensory neuron. D is the anterior horn composed of the cell bodies of motor neurons. C and D are gray matter. Outside the horns and the commissure that connects them is the white matter.
