MICROANATOMY

Detailed explanation-1: -Messages, in the form of electrical impulses, constantly travel back and forth between the brain and other parts of the body. A special cell called a neuron is responsible for carrying these messages.

Detailed explanation-2: -Neurons and Glial Cells. The nervous system is made up of neurons, the specialized cells that can receive and transmit chemical or electrical signals, and glia, the cells that provide support functions for the neurons. A neuron can be compared to an electrical wire: it transmits a signal from one place to another.
