Detailed explanation-1: -Answer. Explanation: Pain receptors, also called nociceptors, are a group of sensory neurons with specialized nerve endings widely distributed in the skin, deep tissues (including the muscles and joints), and most of visceral organs.

Detailed explanation-2: -Afferent neurons in the dorsal roots carry impulses from the body’s sensory receptors to the spinal cord, where the information begins to be processed.

Detailed explanation-3: -For example, if you step on something sharp, the nerves in your foot send a pain signal up your spinal cord to your brain. When your brain recognizes the danger, it sends another signal down your spinal cord to the nerves in your leg and foot muscles, telling them to pull away from the object.
