Motor End Plates
[100X]
Please Note:
The motor end plates at the distal ends of the axon terminal filaments of a motor nerve. The plates represent the nervous contribution to the neuromuscular junctions.
The axon terminal filaments are the segmented lines leading to the plates. The segmented appearance of the nerve fibers is due to presence of the Schwann cells around the fibers and the nodes of Ranvier between the Schwann cells.
The plates shown here are "ending" [innervating] on teased skeletal muscle fibers.
