Describe the structure of a multipolar neuron.

Text Solution

Verified by Experts

Multipolar neurons have one axon and two or more dendrites. Most nerurons in our body are multipolar neurons.
A neuron usually consists of a cell body with one to many dendrites and a single axon.
Neurons : Neurons are the functional units. of nervous tissue. These are electrically excitable cells which receive, initiate, and conduct/transmit impulses. When a neuron is stimulated, an electric disturbance (action potential) is generated which swiftly travels along its plasma membrane. A neuron usually consists of a "cell body with one to many dendrites and a single ахоп.
Cell body : It is also called perikaryon, cyton or soma. It contains abundant granular cytoplasm and a large spherical nucleus. The cytoplasm has Nissl bodies (they represent RER, the sites of protein synthesis), neurofibrils and lipofuschin granules.
Dendrites : Several short, branched processes which arise form the cyton are called dendrites. They also contain Nissl bodies and neurofibrils. They conduct nerve impulses towards the cell body (afferent processes).
Axon : An axon is a single, long, cylindrical process that originates from a region of the cyton called axon hillock. Plasmalemma of an axon is called axolemma, and the cytoplasm is called axoplasm, which contains neurofibrils. However, Nissl bodies are absent. An axon may give rise to collateral branches. Distally it branches into many fine filaments called telodendrites, (axon terminals), which end in bulb like structures called synaptic knobs or terminal boutons. Synaptic knobs possess .synaptic vesicles. containing chemicals called neurotransmitters.
