Define nervous tissue
Nervous or the nerve tissue is the main tissue of our nervous system. It monitors and regulates the functions of the body. Nervous tissue consists of two cells: nerve cells or neurons and glial cells, which help transmit nerve impulses and also provide nutrients to neurons. The brain, Spinal Cord, and nerves are composed of nervous tissue, they are specialized for being stimulated to transmit stimulus from one to another part of the body rapidly.
Structure Of Nervous Tissue
It is made of nerve cells or neurons, all of which consist of an axon. Axons are long stem-like projections emerging out of the cell, responsible for communicating with other cells called the Target cells, thereby passing impulses
The main part is the cell body which contains the nucleus, cytoplasm, and cell organelles. Extensions of the cell membrane are referred to as processes.
Dendrite is a highly branched process, responsible for receiving information from other neurons and synapses (specialized point of contact). Information of other neurons is provided by dendrites to connect with their cell body.
Information in a neuron is unidirectional as it passes through neurons from dendrites, across the cell body down the axon.
