What are the basic parts of the neuron and what is their function?

Nervous system cells are called neurons. They have three distinct parts, including a cell body, axon, and dendrites. These parts help them to send and receive chemical and electrical signals.

What is the basic structure of a neuron?

A neuron has 4 basic parts: the dendrites, the cell body (also called the “soma”), the axon and the axon terminal.

What are the three basic neurons?

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

  • Sensory neurons.
  • Motor neurons.
  • Interneurons.
  • Neurons in the brain.

What are the basic properties of neurons?

The primary components of the neuron are the soma (cell body), the axon (a long slender projection that conducts electrical impulses away from the cell body), dendrites (tree-like structures that receive messages from other neurons), and synapses (specialized junctions between neurons).

What is the basic unit of the nervous system?

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

What are the parts of a neuron quizlet?

Terms in this set (10)

  • Dendrites. Branches of the neuron that receive chemical signals from other neurons.
  • Cell body. Controls neuron activity.
  • Nucleus. Contains DNA of the cell.
  • Axon. Sends electrical signals away from the neuron.
  • Myelin.
  • Terminal Fibers.
  • Terminal Button.
  • Synaptic Gap.

What are the three main parts of the nervous system?

The CNS is comprised of the brain, cerebellum and spinal cord. Remaining neurons, and associated cells, distributed throughout the body form the PNS. The nervous system has three broad functions: sensory input, information processing, and motor output.

What are the 8 parts of the neuron?

  • Dendrites. Receives information from another neurons Axon Terminal through the Synapse.
  • Cell Body/Soma. Receives message from Dendrites.
  • Axon. Receives message from Cell Body/Soma.
  • Axon Terminal. Receives message from Axon.
  • Myelin Sheath.
  • Node of Ranvier.

  • Synapse.

What are the main parts of a nerve cell quizlet?

Terms in this set (7)

  • Neuron. Nerve cell that carries impulses throughout the body.
  • Dendrites. short fibers that branch out from the cell body and pick up incoming messages.
  • Nucleus. a part of the cell containing DNA and RNA and responsible for growth and reproduction.
  • Axon.
  • axon terminals.
  • Soma cell (cell body)
  • Myelin sheath.
