New cards

1

excess of positive sodium ions outside the axon

2
New cards

2

pressure on the pacinian corpuscles increases and layers around the axon are distorted

3
New cards

3

stretch-mediated sodium ion channels in the membrane of the axon are opened

4
New cards

4

this allows Na+ ions to move into the axon via facilitated diffusion

5
New cards

5

this changes the electrical potential difference across the axon membrane, axon more positively charged

6
New cards

6

this triggers a nerve impulse along the axon to the CNS

7
New cards

7

this is called a generator potential as the change in electrical potential is when the receptor is stimulated
