The Pacinian corpuscle senses changes in pressure in the skin. Explain how pressure causes the cell to change its membrane potential to elicit a nerve response.
- Pressure causes the membrane to become deformed/stretched.2) Sodium ion channels open - diffuse in3) Greater pressure = more channels open, greater potential difference change4) Threshold potential reached, nerve impulse created (saltatory conduction, charge diffusion)
