What is function unit of nervous system?

Neurons are the basic functional units of the nervous system, and they generate electrical signals called action potentials, which allow them to quickly transmit information over long distances.

What is the unit block of nervous system?

A neuron is a nerve cell that is the basic building block of the nervous system. Neurons are similar to other cells in the human body in a number of ways, but there is one key difference between neurons and other cells. Neurons are specialized to transmit information throughout the body.

Which is absent in neuron?

Centrioles – Centriole is a cylindrical organelle. This organelle is composed of a protein which is called tubulin. … Neurons lack the centrioles which prevent the neurons to divide as centrioles are responsible for dividing the cell into two. So, the option C is the correct option for this question.

What is Soma in neuron?

Soma. The soma, or cell body, is where the signals from the dendrites are joined and passed on. The soma and the nucleus do not play an active role in the transmission of the neural signal. Instead, these two structures serve to maintain the cell and keep the neuron functional.
