What types of cells are in nervous tissue?
Although the nervous system is very complex, there are only two main types of cells in nerve tissue. The actual nerve cell is the neuron. It is the “conducting” cell that transmits impulses and the structural unit of the nervous system. The other type of cell is neuroglia, or glial, cell.
What are the two types of cells in nervous tissue?
There are two broad classes of cells in the nervous system: neurons, which process information, and glia, which provide the neurons with mechanical and metabolic support.
What are the main cells of the nervous system?
Main. The central nervous system (CNS) is now thought to consist of three main cell types: neurons, glial cells and vascular cells.
How many types of nerve cells are there?
For the spinal cord though, we can say that there are three types of neurons: sensory, motor, and interneurons.
What are the 6 types of glial cells?
There are six types of neuroglia, each with different functions:
- Ependymal cell.
- Satellite cell.
- Schwann cell.
What are the 4 types of Neuroglial cells?
Based upon their appearance, function, and origin, four types of glial cells have been identified in the central nervous system: astrocytes, oligodendroglia, ependymal cells, and microglia.

What is the nervous tissue function?
Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning.
What are neurological cells?
Neuroglia are a large class of neural cells of ectodermal (astroglia, oligodendroglia, and peripheral glial cells) and mesodermal (microglia) origin. Neuroglial cells provide homeostatic support, protection, and defense to the nervous tissue.
What are the 4 types of neurons?
Neurons are divided into four major types: unipolar, bipolar, multipolar, and pseudounipolar.
Are neurons cells?
Neurons (also called neurones or nerve cells) are the fundamental units of the brain and nervous system, the cells responsible for receiving sensory input from the external world, for sending motor commands to our muscles, and for transforming and relaying the electrical signals at every step in between.
What are the types of cells the make up the nervous tissue?
Nervous tissue consists of two main types of cells: neurons and neuroglia . Nerve cells, or neurones (also written ‘neurons’) transmit nerve impulses that move information around the body. Neuroglia are also known simply as ‘glia’ and have various functions in support of nerve cells but do not transmit nerve impulses themselves.
What are the three types of nerve cells?
Nerves and Nerve Types. There three types of nerves in the central nervous system: motor neurons, sensory neurons and autonomic neurons. Motor nerves send impulses or signals from the brain and spinal cord to all of the muscles in the body.
Do nerve cells have tissues in them?
Each nerve is covered on the outside by a dense sheath of connective tissue, the epineurium . Beneath this is a layer of fat cells, the perineurium, which forms a complete sleeve around a bundle of axons. Perineurial septae extend into the nerve and subdivide it into several bundles of fibres. Surrounding each such fibre is the endoneurium.
What tissue does the nerve cell make up?
Nerves are composed of myelinated and unmyelinated axons, Schwann cells surrounded by connective tissue. The three layers of connective tissue surrounding each nerve are: Endoneurium. Each nerve axon, or fiber is surrounded by the endoneurium, which is also called the endoneurial tube, channel or sheath.
