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+

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.
