Nerve cells transfer their energy, or "talk", per various other throughout a small space called a synapse (Fig. 12). A neuron has lots of arms called dendrites, which act like antennae picking up messages from other nerve cells. These messages are passed to the cell body, which determines if the message should be passed along. Vital messages are passed to the end of the axon where sacs including neurotransmitters open into the synapse. The natural chemical molecules go across the synapse as well as fit into special receptors on the obtaining nerve cell, which promotes that cell to hand down the message. There are lots of shapes and sizes of nerve cells, yet all consist of a cell body, dendrites and an axon.
The color is extreme, and also no development procedure is required for visualization. However, assays might have varying level of sensitivity relative to their target agents in LFAs.
