Answers
Neurons (also called neurones or nerve cells) are the fundamental units of the brain and nervous system, the cells responsible for receiving sensory input from the external world, for sending motor commands to our muscles, and for transforming and relaying the electrical signals at every step in between.

QUESTION :-
What is a neuron ?? Write the structure and functions of a neuron
ANSWER :-
Neurons, also known as nerve cells, send and receive signals from your brain. While neurons have a lot in common with other types of cells, they’re structurally and functionally unique.
Specialized projections called axons allow neurons to transmit electrical and chemical signals to other cells. Neurons can also receive these signals via rootlike extensions known as dendrites.
At birth, the human brain consists of an estimated 100 billion neuronsTrusted Source. Unlike other cells, neurons don’t reproduce or regenerate. They aren’t replaced once they die.
The creation of new nerve cells is called neurogenesis. While this process isn’t well understood, it may occur in some parts of the brain after birth.
