PATHOLOGY

Detailed explanation-1: -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.

Detailed explanation-2: -Synapses are chemical or electrical junctions that allow electrical signals to pass from neurons to other cells. Electrical signals in muscles cause contraction and movement.
