Warm receptors
The general senses associated with the body surface can be classified according to the stimulus type. These include mechanoreceptors, which are stimulated by light touch, stretch, or vibration, and thermoreceptors, which are stimulated by deep pressure, stretch, or vibration.
Thermoreceptors include cold receptors, which are most sensitive to temperatures between 25°C (77°F) and 45°C (113°F), and warm receptors, which are most sensitive to temperatures between 10°C (50°F) and 20°C (68°F).
Nociceptors are pain receptors that respond to tissue trauma, which may include a cut or pinch, extreme heat or cold, or excessive pressure. These receptors possess structural differences at the dendrite ends of sensory neurons. Those with unencapsulated free nerve endings include pain, cold, and heat receptors; those with encapsulated nerve endings include tactile corpuscles and lamellated corpuscles.
