|
Definition
| The more intense the response, the more frequent the APs |
|
|
Term
| How does skin stretch produce a receptor potential? |
|
Definition
| Mechanoreceptors in the plasma membrane are opened by stretch to allow an ionic current |
|
|
Term
| How do chemoreceptors produce a receptor potential? |
|
Definition
| They are activated by a molecule which causes a second messenger cascade activating cAMP to produce an ionic current |
|
