ANATOMY

Detailed explanation-1: -To feel pain, impulses travel from the receptors in your hand to the spinal cord through sensory neurons. In the spinal cord, the sensory neurons synapse with interneurons that carry impulses to the sensory cortex area of the cerebrum in your brain.

Detailed explanation-2: -When a message comes into the brain from anywhere in the body, the brain tells the body how to react. For example, if you touch a hot stove, the nerves in your skin shoot a message of pain to your brain. The brain then sends a message back telling the muscles in your hand to pull away.

Detailed explanation-3: -For example, a simple reflex arc happens if we accidentally touch something hot. Receptor in the skin detects a stimulus (the change in temperature). Sensory neuron sends electrical impulses to a relay neuron, which is located in the spinal cord of the CNS.

Detailed explanation-4: -The spinal cord, basically a highway for nerves, streamlines sensory and motor signals to the brain and the body. Information detected by sensory receptors in the periphery is transmitted along ascending neural tracts in the spinal cord.

Detailed explanation-5: -The pathway responsible for touch and proprioception is called the lemniscal pathway. The first axon in this pathway runs along the dorsal root of the spinal nerve and up the dorsal column of the spinal cord.
