Question

Why is a neuron called the functional and structural part of the nervous system?

Answer 1

Explanation:

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

Answer 2

Neurons are the structural and functional units of the nervous system because they transmit electrical signals, called nerve impulses.
