Histology (Cells) of the Nervous System â¢ 2 major categories of cells are found in the nervous system:â¢ 1. Nerve cells (neurons) âcarry impulses and are electrically excitable.â¢ 2. Glial cells (neuroglia)- do not carry impulses, not electrically excitable.â¢ We will discuss glial cells first.â¢ Glial Cells (Neuroglia): These cells do not carry electrical impulses as they are not electrically excitable. There are several types of glial cells with a number of different functions.
The other type of cell is glia, which protects the former. Neurons have three main parts: 1  Cell body or Soma: it is the main part of the cell, the one that makes all metabolism and functions. 2  It is very similar to other body cells, except for the difference that neurons do not replicate.3  Axon: it is the longest and most important part of the neuron, it transmit the impulse.
