Are Meissner, Pacinian, and Ruffini corpuscles part of the skin of part of the nervous system

Are they part of the skin that are just connected to neurons
or are they the ends of very long neurons?

They are mechanoreceptors, that is, they respond to changes of pressure - and are usually found in the dermis; the second layer of skin down. They are a part of the nervous system as they detect stimuli (of pressure) and this stimulus causes the generation of an action potential. The corpuscles are found, as you stated, at the end (or beginning, depending on how you look at it) of myelinated axons.

Hey, so is stimulus sent to the brain through axons? Shouldn't they go through dendrites? I've been told that neurons only receive stimuli through dendrites, and only send information through axons.

Is it wrong, what I've been told??
