The Structure of the Neuron Neurons: Nerve cells, the basic elements of the nervous system Have a cell body that contains a nucleus Physically held in place by glial cells Glial cells provide nourishment to neurons and insulate them Help repair damage Support neural functioning.

The question is incorrect. The correct question is as follows:

Nerve cells, the basic elements of the nervous system, have a cell body that contains a nucleus. Physically held in place by glial cells. They have the ability to communicate with other cells and transmit information across relatively long distances

Neurons.

Explanation:

The nervous system is one of the most important system of the body that coordinates and maintains the other system of the body. The nervous is divided into two main parts -  peripheral nervous system and central nervous system.

Neuron is the structural and the functional unit of the nervous system. The nervous system contains the million of neuron that conducts the information from one part of the body to another. They are held together by the glial cells also know as glue and travels communication through the long distances.

Thus, the answer is neurons.
