What is simple meaning of neuron?

Definition of neuron.

A neuron is the basic unit of the nervous system.

Simple explanation of neuron.

Neurons are like the building blocks of our nervous system. These tiny cells play a crucial role in communicating information throughout our bodies. Neurons receive signals from other neurons or stimuli from our environment and transmit electrical signals to other neurons or muscles. It's like a telephone system where each neuron is a phone that receives, processes, and passes on messages to other phones.

Neurons have a specialized structure that allows them to perform this communication:

1. Cell body (soma): This is the "brain" of the neuron, where information is received and integrated.

2. Dendrites: These are branches that extend from the cell body and act like antennas, receiving signals from other neurons through chemical messengers called neurotransmitters.

3. Axon: The axon is like the "output wire" of the neuron. It carries electrical signals away from the cell body and passes them on to other neurons or muscles.

When a neuron receives enough signals from other neurons, it generates its electrical signal called an "action potential." This signal travels down the axon and triggers the release of neurotransmitters from the axon terminals. These neurotransmitters then bind to receptors on neighboring neurons or muscle cells, continuing the communication process.
