Pain and suffering
The skin is the largest organ in the body, and it is full of receptors. Skin receptors are nerve endings that detect touch, pressure, vibration, temperature, and pain, allowing the body to sense its environment. The types of receptors are: Mechanoreceptors Meissner's corpuscles: Detect light touch and changes in texture; found in the dermal papillae, they are rapidly adapting. Pacinian corpuscles: Sense deep pressure and vibration; located deep in the dermis, they are rapidly adapting. Ruffini endings: Respond to deep pressure and skin stretch; they are slowly adapting. Merkel cells: Detect sustained light touch, pressure, and texture; they are slowly adapting and found in the epidermis. Hair follicle receptors: Detect hair movement and light touch. Other receptors Free nerve endings: These are the primary receptors for pain (nociceptors) and temperature (thermoreceptors). Pain receptors (nociceptors) : Free nerve endings th...
