1
Q
What does the Pacinian corpuscle respond to?
A
Pressure changes
2
Q
What is the pacinian corpuscle made of?
A
Many layers of lamellae surrounding the sensory neurone
3

A
1) Increased pressure deforms stretch-mediated sodium channels
2) Sodium ion channel protein opens and sodium ions diffuse in
3) Depolarisation leads to generator potential
