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. Different neurons have different jobs.
Detailed explanation-2: -Ascending pathway to the brain: Sensory information travels from the body to the spinal cord before reaching the brain. This information ascends upwards using first, second, and third-order neurons. First-order neurons receive impulses from skin and proprioceptors and send them to the spinal cord.
Detailed explanation-3: -Nerves are bundles of neuronal fibres that transmit signals, which are electric impulses. These signals are transmitted from the periphery, for example, the toe, to the Spinal Cord and the Brain by sensory neurons.
