WebOct 6, 2024 · Our sense of touch is controlled by a huge network of nerve endings and touch receptors in the skin known as the somatosensory system. This system is responsible for all the sensations we feel – cold, hot, smooth, rough, pressure, tickle, itch, pain, vibrations, and more. Within the somatosensory system, there are four main types of … 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-peptide and not a neuro-transmitter because it's not released by a neuron) released are picked up by the afferent neurons and that trigger the action potential. how to mount garmin livescope to your boatWebTerminal endings of sensory neurons.
