Nervous tissue is the term for groups of organized cells in the nervous system, which is the organ system that controls the body’s movements, sends and carries signals to and from the different parts of the body, and has a role in controlling bodily functions such as digestion.
What is the main function of nervous tissue? The main function of nervous tissue is to receive stimuli and send signals to the brain and spinal cord. These signals are sent to the muscles via the nerves.
Your nervous system uses nerve cells called neurons to send signals, or messages, all over your body. These electrical signals travel among your brain, skin, organs, glands and muscles. The messages help you move your limbs and feel sensations, like pain.
Functions of the nervous system are sensory input, integration, control of muscles and glands, homeostasis, and mental activity. Nervous tissue is composed of neurons, also called nerve cells, and neuroglial cells. Four types of neuroglia found in the CNS are astrocytes, microglial cells, ependymal cells, and oligodendrocytes.
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.
Having looked at the components of nervous tissue, and the basic anatomy of the nervous system, next comes an understanding of how nervous tissue is capable of communicating within the nervous system. Before getting to the nuts and bolts of how this works, an illustration of how the components come together will be helpful.
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 4.5.1 The Neuron).
