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

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. 

Keratinocytes can produce only protein. 

The cells of the stratum spinosum synthesize keratin. 

Desmosomes are the structures which attach keratinocytes to each other.
