Verified by Toppr. The structure of neuron: Nerve cells or neurons are the structural and functional units of the nervous system. It consists of three major parts namely, cell body, dendrites, axon. Cell Body: It is irregular in shape or polyhedral. It contains cytoplasm and certain granular bodies called Nissl's granules which contain a group ...
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).
Neurons are the fundamental unit of the nervous system. Neurons are also called as nerve cells. The main function of the neurons is to pass the receiving information and send appropriate signals to the rest parts of the body. The signals received are in the form of electrical signals. Neuron comprises of dendrite, axon and cell body.
Describe the structure of neuron with the help of a neat labelled diagram. The neurons are the cells in the brain or nervous system. It is composed of a cell body and an axon. The cell body is also called as the cyton. There are the prominent nucleus and Nissl's granules in the cell body. There are short brush-like structures arising from the ...
A neuron is the structural and functional unit of the nervous system. It is an electrically excitable cell that processes and transmits information by electrical and chemical signaling. The neuron consists of three main parts the cell body or soma, dendrites, and axons. 1. Cell body: The cell body is the central region which is the most ...
The structure of neuron: Nerve cells or neurons are the structural and functional units of the nervous system. It consists of three major parts namely, cell body, dendrites, axon. Cell Body: It is irregular in shape or polyhedral. It contains cytoplasm and certain granular bodies called Nissl's granules which contain a group of ribosomes for ...
Cell body: It contains a nucleus, mitochondria, and other cell organelles. It maintains the growth of the cell. Axon: It conducts messages away from the cell body and passes to the next neuron. The dendrites tend to taper and are often covered with little bumps called spines. In contrast, the axon tends to stay the same diameter for most of its ...
An axon or nerve fibre, is a long, slender projection of a nerve cell, or neuron, in vertebrates, that typically conducts electrical impulses known as action potentials away from the nerve cell body. The myelinated nerve fibres contain a myelin sheath, surrounding the axons of the nerve cells.

A typical structure of neuron consists of a cell body and two processes, those are Dendron and Axon. The cell body of a neuron is like other cells of the body, consisting of a nucleus and cytoplasm covered by a plasma membrane. The cytoplasm contains various organelles and inclusions. In adult nerve cells, the centrosome is absent or inactive ...
