Neurons (or nerve cells) are specialized cells that transmit and receive electrical signals in the body. Neurons are composed of three main parts: dendrites, Most neurons lack centrioles in their somas, which is the other reason why scientists believed for so long that adult neurons didn't divide. On either side of the cell body are the parts of the neuron that make it famous: the dendrite and the axon. Association neurons ( interneurons) are located in the CNS and transmit impulses from sensory neurons to motor neurons. More than 90 percent of the neurons of the body are association neurons. Neurons are structurally classified into three groups, as shown in Figure 1: Multipolar neurons have one axon View LAB (4).docx from BSIT-FT 201 at Southern Luzon State University.

It is different from other cells in two ways: Neuron has branches (processes) called axon and dendrites.

Wetzel 3, Sergey In Anatomy & Physiology, you will have to know the structure of a neuron and how each structure functions. For instance, as a student you must be familiar with how the axon and dendrites carry electrical signals and how Schwann cells form the myelin sheath of the axon.

A neuron is a cell that transmits nerve impulses. It consists of the following parts, shown in Figure 1: The cell body (soma or perikaryon) contains the nucleus and other cell organelles. There are clusters of rough endoplasmic reticulum (not shown in Figure 1) that are called Nissl bodies or are sometimes referred to as chromatophilic substances.
