1 answer:
A nerve cell consists of a cell body or soma, a main fiber (axon) and many small branches (dendrites).
<h3>What is a neuron?</h3>- A neuron or nerve cell forms the basic unit of brain and nervous system.
- These cells receive stimulus from the external world, relay the information to brain and help to generate a response.
- The neurons communicate with each other via special connections called synapses where they release neurotransmitter.
- A typical neuron consists of a cell body (soma), dendrites (brings information), and a single axon (send information away from neurons).
- The dendrites and axon branch out from the cell body.
- Cell body contains nucleus and specialized organelles.
- At the tip of axon are axon terminals where neurotransmitters are released to transmit signal across the synapse to other cell.
