Question

What is the basic unit of the nervous system?

Answer 1

The basic unit of all vertebrate nervous tissue is the neuron.

Explanation:

Neurons are specialised cells that can receive and transmit action potentials ( impulse) .

Neurons have a large cell body and several cell projections called dendrites. Dendrites receive electrochemical signals which creates changes in voltage of the cells. This signal is transmitted from one neuron to another across a synapse.

Several neurons group together to form ganglia. Bundles of axons along which neurons transmit and receive impulses are called nerves.
