Question

Identify the two basic types of cells in the nervous tissue. Of the two types of cells, which one is most abundant?

Answer 1

The two basic types of cells found in the nervous system are :

1. Neurons also known as nerve cells and

2. Neuroglia (glia)

Neurons are the cells which transmit the impulses from the sense organs to the brain and from the brain to the sense organs. A typical neuron consists of dendrites, the cell body, and an axon.

Glial cells are the supporting cells. There are six types of neuroglia—four in the central nervous system and two in the PNS. These glial cells are involved in many specialized functions apart from the support of the neurons. Neuroglia in the CNS include astrocytes, microglial cells, ependymal cells, and oligodendrocytes. In the PNS, satellite cells and Schwann cells are the two kinds of neuroglia.

Abundant will be neurons. They are 9-15 billion in a human.
