NEET BIOLOGY

Detailed explanation-1: -Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the “conducting” cell that transmits impulses and the structural unit of the nervous system.

Detailed explanation-2: -Nervous tissue is characterized as being excitable and capable of sending and receiving electrochemical signals that provide the body with information. Two main classes of cells make up nervous tissue: the neuron and neuroglia (Figure 1).

Detailed explanation-3: -Nervous tissue contains two major cell types, neurons and glial cells. Neurons are responsible for communication through electrical signals. Glial cells are supporting cells, allowing neuron function.

Detailed explanation-4: -Neurons. Neurons are the cells considered to be the basis of nervous tissue. They are responsible for the electrical signals that communicate information about sensations, and that produce movements in response to those stimuli, along with inducing thought processes within the brain.

Detailed explanation-5: -Neurons and Glial Cells. The nervous system is made up of neurons, the specialized cells that can receive and transmit chemical or electrical signals, and glia, the cells that provide support functions for the neurons.
