What are the functions of nervous tissue?

The main components of the nervous system include nerve tissue. Nervous tissue is composed of neurons and glia. Nerve cells are also called nerve cells. Neurons sense stimuli and transmit excitement. Nerve tissue can transmit nerves. Many people do not understand what are the functions of nervous tissue. What are the functions of nervous tissue? Let’s take a look at it next.

1. Introduction to Nervous Tissue

Nervous tissue is one of the basic tissues of humans and higher animals and is the main component of the nervous system. Nervous tissue is composed of neurons (nerve cells) and glia. Neurons are the main components of nervous tissue. They have the function of receiving stimulation and transmitting excitement. They are also the basic functional units of neural activity. Glia play a supporting, protective and nutritional role in neural tissue.

2. The structure of human nervous system

The human nervous tissue is mainly composed of nerve cells. Nerve cells, also called neurons, consist of two parts: the cell body and the processes. Generally, each neuron has a long axon with few branches and several short dendrites with tree-like branches. The processes of neurons are also called nerve fibers. The tiny branches at the end of nerve fibers are called nerve endings, which are distributed to the tissues they control. Neurons can become excited when stimulated and can transmit the excitement along nerve fibers.

3. Functions of Nervous Tissue

It mainly generates nerve impulses in response to stimulation and can transmit nerve impulses. In addition, nerves can integrate information and transmit some nerve impulses to effectors (muscles, glands) to make the effectors active (muscle contraction, gland secretion). For example, if the hand is on fire, the hand can quickly dodge, which is done under the action of nerve tissue. Fire stimulates the receptor, and the receptor generates nerve impulses. The nerve impulses are transmitted to the central nervous system along the afferent nerves. On one hand, they are transmitted to the brain, making the brain feel the fire on the hand, and on the other hand, they are transmitted to the efferent nerves, making the muscles contract quickly to dodge the fire.
