Four major tissues of the human body

Nerve tissue is the main component of the nervous system

It is composed of nerve cells and neuroglial. Nerve cells are the structural and functional units of the nervous system, also known as neurons. There are about a billion neurons in an adult. They have the functions of receiving stimulation, transmitting impulses, and integrating information. Some neurons also have endocrine functions. Glia is a general term for glial cells. Its number is about 10 to 50 times that of neurons. It is mainly distributed between neurons and has no function of conducting impulses. Instead, it provides support, nutrition, insulation and protection to neurons. And other effects.
