Nervous tissue

neuron

Nervous tissue consists of nerve cells, or neurons, which are specialized for the generation and conduction of electrical events, and of supporting cells, which provide the neurons with anatomical and functional support. Supporting cells in the brain and spinal cord are referred to as neuroglial cells, or often simply as glial cells. Each neuron consists of three parts: (1) a cell body, (2) dendrites, and (3) an axon. The cell body contains the nucleus and serves as the metabolic center of…

Nerve tissue is specialized for chemical and electrical communication and consists of neurons and supporting cells, called glial cell. Glial cells constitute most of the volume of nervous tissue. They protect and assist neurons by communication, but do not transmit long-distance signals. See chapter 12 for more detail on neurons and glial cells.

The nervous tissue is the source of communication throughout the body. Nervous cells are composed of neurons, specialized cells that allow communication throughout the body. Nervous tissues cannot replication, therefore, you are out of luck if one atrophies. Nervous tissues are found in the brain, spinal cord, and the peripheral nerves. There are neurons and neuroglia.

Histology! ♦ Muscle tissue is highly cellular, well-vascularized tissue that is responsible for most types of body movement♦ Connective tissue protects, supports and binds together different parts of the body (e.g., fat, ligaments, tendons, fascia)♦ Epithelial tissue is composed of sheets of cells that cover a body surface or line a body cavity (e.g., skin, inner and/or outer lining of the organs, etc.)♦ Nervous tissue consists of neurons and supporting cells
