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

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

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

Keratinocytes can produce only protein. 

The cells of the stratum spinosum synthesize keratin.
