Pacinian corpuscles are found in the dermal papillae and can detect light touch or low-frequency vibration better than mechanoreceptors. 

Pacinian corpuscles help detect pressure and high-frequency vibration as well as the difference between paper and glass. 

Desquamation is the process that involves the gradual breakdown of desmosomes and eventual shedding from the surface. 

Desmosomes are the structures which attach keratinocytes to each other. 

Keratinocytes can produce only protein.
