Mechanoceptors Flashcards
Describe the function of the Mechanoceptors
Meissner Corpuscle = Dynamic deformation Pacinian corpuscle = Vibration Ruffini corpuscle = stretch Merkel cell complex = indentation depth C - fibres = touch Adelta = noxious stimuli
Describe the locaiton of the mechanoceptors
Ruffini corpuscle and the Pacinian corpuscles are deep in dermis
Meissner Corpuscle and Merkel cell complex in the upper layer of dermis
C - fibres and Adelta fibres in the epidermis
Describe the adaption rate of mechanoceptors
The Ruffini corpuscle and the merkel cell comples are slowly adapting as are the c-fibres and the Adelta fibres. The Pacinian and the meissner corpuscles are rapidly adapting
Describe the receptor Fields of the Mechanoceptors
The Deep receptors, Pacinain and Ruffini have large receptor fields whereas the meissner and merkels have small fields as do the C-fibres and the Adelta fibres
