Lamellar corpuscles (pacinian)respond to: a) Deep within the dermal layer of the skin and the hypodermis. See the answer. If the brain perceives the threat as credible, it creates the sensation of pain to direct attention to the body part, so the threat can hopefully be mitigated; this process is called nociception The relative density of touch receptors in various parts of the body. They respond to fine touch and pressure, but they also respond to low-frequency vibration or flutter. Why is the nonadaptability of pain receptors important?

Each corpuscle is located in a small dermal papillae, a tiny projection of the epidermis that is visible under a microscope. When these corpuscles are deformed by pressure, they send neural signals to the brain. A nociceptor ("pain receptor") is a sensory neuron that responds to damaging or potentially damaging stimuli by sending “possible threat” signals to the spinal cord and the brain.
