Detailed explanation-1: -It consists of specialized cells called neurons that serve as the nervous system’s structural-functional unit. The neurons or nerve cells carry messages throughout the nervous system through electrochemical impulses. These are the longest cells present in the human body.
Detailed explanation-2: -A special cell called a neuron is responsible for carrying these messages. There are about 100 billion neurons in the human brain. A neuron has three main parts. The cell body directs all activities of the neuron.
Detailed explanation-3: -Neurons communicate with each other via electrical events called ‘action potentials’ and chemical neurotransmitters.
Detailed explanation-4: -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.
Detailed explanation-5: -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.
