Pressure Receptors - The Pacinian Corpuscle Flashcards
1
Q
What are pressure receptors
A
- connected to a sensory neuron
2
Q
What is the structure of the pressure receptor?
A
- Pacinian corpuscle
- single nerve fiber
- capsule
- myelin sheath
3
Q

A
- Na+ channels are opened - they are physical pushed open and the membrane depolarises
4
Q
What happens when some of the Na+ channels open?
A
- That encourages more and more Na+ channels to open by positive feedback
