Meissner's and pacinian corpuscles
Web7 jul. 2024 · 4 Tactile corpuscles (Meissner’s corpuscles) perceive sensations of fine touch, pressure and low-frequency vibration. They adapt to stimulation with 1 second after contact. 5 Lamellated corpuscles (Pacinian corpuscles) are sensitive to deep pressure and are found deep in the dermis and hypodermis. Advertisement Advertisement WebSpecifically, the corpuscle is the nerve ending, or the tip of a very specialized peripheral axon. The Merkel's disk, however, is not a neuron. The neuro-peptides (called a neuro …
