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.
