GENERAL HISTOLOGY

Detailed explanation-1: -The nervous system uses tiny cells called neurons (NEW-ronz) to send messages back and forth from the brain, through the spinal cord, to the nerves throughout the body. Billions of neurons work together to create a communication network.

Detailed explanation-2: -Your brain is made up of billions of cells called neurons. Your neurons carry information in the form of electrical pulses. Neurons communicate with each other and the rest of your body at special meeting points called synapses.

Detailed explanation-3: -The three primary roles of the spinal cord are to send motor commands from the brain to the body, send sensory information from the body to the brain, and coordinate reflexes. The spinal cord is organized segmentally, with thirty-one pairs of spinal nerves emanating from it.
