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. There are about 100 billion neurons in the human brain.
Detailed explanation-2: -Cells of the nervous system, called nerve cells or neurons, are specialized to carry “messages” through an electrochemical process. The human brain has approximately 86 billion neurons. To learn how neurons carry messages, read about the action potential. Neurons come in many different shapes and sizes.
Detailed explanation-3: -Neurons send what are known as electrochemical signals. Once a neuron has been stimulated by some sort of stimulus, it generates an electric potential that travels down the length of the cell. This is the ‘electro’ part of electrochemical.
Detailed explanation-4: -Answer and Explanation: Neurons are specialized cells of the nervous system that are able to conduct chemo-electrical impulses called action potentials. These impulses are generated from the depolarization of the neuron’s membrane as a result of a stimulus. No other cell can do perform this function.
Detailed explanation-5: -Axon: An axon is a tube-like structure that propagates the integrated signal to specialized endings called axon terminals. The axon carries the action potential to the next neuron. Neurons usually have one or two axons.
