Flashcards in Pacinian Corpuscle Deck (4):
What is a pacinian corpuscle?
They are mechanoreceptors- they respond to mechanical stimuli such as pressure.
They occur deep in the skin and are most abundant on the fingers, the soles of the feet and external genitalia.
What do pacinian corpuscles contain?
The end of a sensory neurone- a 'sensory neurone ending', which is wrapped in loads of connective tissue called lamellae.
As with all sensory neurones, a pacinian corpuscle:
Is specific to a single type of stimulus- mechanical pressure.
It produces a generator potential by acting as a transducer- the role of which is to convert one form of an energy into another.
