Cell processes are elongated parts extending from the cell body and can be divided into Dendrite And axons. The branches produced by the extension part of the cell body are called dendrites, which are the entrances to receive information from other neurons. Each neuron can have one or more dendrites, which can receive stimulation and transmit excitation to the cell body. At the same time, dendrites are not necessarily the only channel for nerve afferent. It can also be the cell membrane. The structure of dendrites is similar to that of perikaryon. There are many spiny small processes on the dendrite branches, and the dendritic spines are the main parts of synapses between neurons. Dendritic spines and dendrites greatly increase the receptive surface of neurons. The main function of dendrites is to receive stimulation.
Axon refers to the thin and long process that animal neurons transmit nerve impulses to leave the cell body. Each neuron has only one axon, which generally emanates from the cell body, and the emitting part is often conical, called "axon". There was no Nissl body in the axon and the thalamus. Axons are usually thinner than dendrites. The role of axons is to transmit the impulses sent out by cell bodies to another neuron or effectors distributed in muscles or glands.
