What are the 3 main parts of the nerve cell?

A neuron has three main parts: dendrites, an axon, and a cell body or soma (see image below), which can be represented as the branches, roots and trunk of a tree, respectively.

What is structure of nerve cell?

A nerve cell (neuron) consists of a large cell body and nerve fibers—one elongated extension (axon) for sending impulses and usually many branches (dendrites) for receiving impulses. The membranes are wrapped tightly around the axon, forming a multilayered sheath.

What is nerve cell function?

The nerve cell, also known as a neuron, is the main structural and functional unit of the nervous system. The neurons or nerve cells are primarily involved in receiving and transmitting information from and to the brain. They transfer various messages from different parts of the body to the brain and back.

What are the major functions of a neuron?

The basic functions of a neuron These are to: Receive signals (or information). Integrate incoming signals (to determine whether or not the information should be passed along). Communicate signals to target cells (other neurons or muscles or glands).

What are the three main parts of a neuron what are their functions 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.

What is the role of the nerve cell?

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).
