What is nervous tissue?
Tissue containing neurons that initiate and conduct nerve impulses to coordinate homeostasis, and neuroglia that provide support and nourishment to neurons.
What are neurons?
A nerve cell, consisting of a cell body, dendrites, and an axon.
What are nerve action potentials?
Electrical impulses conducted by neurons to other neurons, to muscular tissue, or to glands. Also called nerve impulses.
What is a dendrite?
A neuronal process that carries electrical signals, usually graded potentials, toward the cell body.
What is an axon?
The usually single, long process of a nerve cell that propagates a nerve impulse toward the axon terminals.
What type of tissue is this?
nervous tissue
Where would you find nervous tissue?
Nervous system.
What are the functions of nervous tissue?
Exhibits sensitivity to various types of stimuli; converts stimuli into nerve impulses (action potentials); conducts nerve impulses to other neurons, muscle fibers, or glands.
What are neuroglia?
Cells of the nervous system that perform various supportive functions. The neuroglia of the central nervous system are the astrocytes, oligodendrocytes, microglia, and ependymal cells; neuroglia of the peripheral nervous system include Schwann cells and satellite cells. Also called glial cells.
