Mechanoceptors Flashcards

1
Q

Describe the function of the Mechanoceptors

A
Meissner Corpuscle = Dynamic deformation
Pacinian corpuscle = Vibration
Ruffini corpuscle = stretch
Merkel cell complex = indentation depth
C - fibres = touch
Adelta = noxious stimuli

Q

Describe the locaiton of the mechanoceptors

A

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

Q

Describe the adaption rate of mechanoceptors

A

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

Q

Describe the receptor Fields of the Mechanoceptors

A

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
