AP PSYCHOLOGY

Detailed explanation-1: -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-2: -Axon. The axon is the elongated fiber that extends from the cell body to the terminal endings and transmits the neural signal.

Detailed explanation-3: -Nociceptors are sensory nerve endings for signaling noxious tissue-damaging stimuli which induce pain in humans. The largest group which responds to noxious heat, mechanical, and irritant chemical stimuli are thus denoted as polymodal receptors.

Detailed explanation-4: -Your nervous system uses specialized cells called neurons to send signals, or messages, all over your body. These electrical signals travel between your brain, skin, organs, glands and muscles.

Detailed explanation-5: -Free nerve endings called nociceptors in the skin have a high threshold for mechanical, chemical, or thermal stimuli and respond only when the intensity of these stimuli is high enough to damage tissue. We perceive the input from these receptors as pain.
