The dorsal root ganglion contains the cell bodies of sensory neurons that bring information from the periphery to the spinal cord. These neurons are pseudounipolar and contain an axon-like process that bifurcates with one branch extending toward the periphery and the other branch heading toward the grey matter of the spinal cord. Fibers heading toward the periphery leave the ganglion through the spinal nerve, where they run together with motor fibers. Fibers leading to the spinal cord travel through the dorsal root.
The motor end plate is a point of junction of a motor nerve fiber and a muscle fiber. The motor endplate is a modified area of the muscle membrane at which the synapse occurs. It has two specializations: (1.) The presence of junctional folds provide a large surface area where acetylcholine from the synaptic end bulb can interact because (2.) the junctional folds contains tens of millions of acetylcholine receptors which are very important when ion channels are activated. When the acetylcholine binds with the receptors it enables sodium to flow into the muscle fiber. The sodium starts an electrical impulse that causes your muscle to contract and shorten.
Basket cells are inhibitory neurons that can be found in the neocortex, cerebellum, and hippocampus. These cells form baskets of axonal arborizations onto and around the somata of target neurons.
