what cells make up the nervous system?

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. The word "neuroglia" means "nerve glue." These cells are nonconductive and provide a support system for the neurons.

In this regard,What cells make up the nervous system quizlet?

There are two main cell types: neurons and neuroglia.

Furthermore,What is the nervous cell made up of?

The basic unit of communication in the nervous system is the nerve cell (neuron). Each nerve cell consists of the cell body, a major branching fiber (axon) and numerous smaller branching fibers (dendrites).

Long,Are neuron 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.

Similarly,What are the two types of cells that make up nervous tissue quizlet?

The two types of cells that comprise nervous tissue are neurons and neuroglia. Neurons are nerve cells. Neuroglia produce myelin, maintain the ionic environment, provide growth factors and support neurons, provide structural support, and play a role in cell-to-cell communication.

How are nerve cells formed?

But in the adult brain, neural circuits are already developed and neurons must find a way to fit in. As a new neuron settles in, it starts to look like surrounding cells. It develops an axon and dendrites and begins to communicate with its neighbors. Stem cells differentiate to produce different types of nerve cells.

What are the 3 nerve cell?

For the spinal cord though, we can say that there are three types of neurons: sensory, motor, and interneurons.

Are nerves made of neurons?

A nerve is a bundle of fibers that receives and sends messages between the body and the brain. The messages are sent by chemical and electrical changes in the cells, technically called neurons, that make up the nerves.

What is the nerve cell function?

Nerve cells (neurones) are 'excitable' cells which can transduce a variety of stimuli into electrical signals, continuously sending information about the external and internal environment (in the form of sequences of action potentials) to the central nervous system (CNS).

What is this cerebrum?

(seh-REE-brum) The largest part of the brain. It is divided into two hemispheres, or halves, called the cerebral hemispheres. Areas within the cerebrum control muscle functions and also control speech, thought, emotions, reading, writing, and learning.

What are glial cells?

Glial cells, also called glial cells or neuroglia, are cell which are non-neuronal and are located within the central nervous system and the peripheral nervous system that provides physical and metabolic support to neurons, including neuronal insulation and communication, and nutrient and waste transport.
