ANATOMY

Detailed explanation-1: -The perception of innocuous and noxious touch sensations rely on special mechanosensitive sensory neurons that fall into two general categories; lowthreshold mechanoreceptors (LTMRs) that react to innocuous mechanical stimulation and high-threshold mechanoreceptors (HTMRs) that respond to harmful mechanical stimuli.

Detailed explanation-2: -Thalamus. Located in the central part of the brain, the thalamus receives sensory messages, such as touch, from the body, and sends the messages to the appropriate part of the brain to be interpreted.

Detailed explanation-3: -Sensory nerves carry signals to your brain to help you touch, taste, smell and see. Motor nerves carry signals to your muscles or glands to help you move and function.

Detailed explanation-4: -Sensory neurons are the nerve cells that are activated by sensory input from the environment-for example, when you touch a hot surface with your fingertips, the sensory neurons will be the ones firing and sending off signals to the rest of the nervous system about the information they have received.
