Topic 6 Receptors Pancinian Corpuscule Flashcards
1
Q
Where are often pancinian corpuscule often situated?
A
Often situated deep in skin at finger and feet.
2
Q
How is resting potential maintenance in Pancinian Corpuscle?
A
The channel to narrow for Na+ to diffuse in so resting potential is maintained.
3
Q
How is voltage gated Na+ open in Pancinian Corpuscle?
A
First stimulated by tap on the arm, lamallae deformed and press on sensory nerve ending
This causes sensory neurone cell membrane to stretch
Na+ channel open make cell membrane more permeable to Na+
4
Q
After Voltage Gated Na+ opened in Pancinian Corpuscle How is action potential caused?
A
Na+ diffuse into cell creating generator potential
If generator potential reaches threshold action potential triggered.
