|
Definition
a1 - contraction of radial muscle iris (mydriasis)
B - inc fluid inflow and weak relaxation of ciliary body (inc intraocular pressure)
- Pupil gets big and eye bulges |
|
|
Term
| Parasympathetic Stimulation on the Eye |
|
Definition
M - constriction of iris sphincter muscle (miosis), constriction of ciliary body (near vision), inc in outflow thru trabecular meshwork
-pupil gets small |

Term
| Sympathetic Stimulation on the Heart |
|
Definition
B1>B2 on the SA node - inc heart rate
B1,2 on the AV node - inc in conduction
B1,2 on the ventricles - inc in contractility |
|
|
Term
| Parasympathetic Stimulation on the Heart |
|
Definition
| M - dec in heart rate and contractility |
|
|
Term
| Sympathetic Stimulation on Blood Vessels |
|
Definition
a1 - constriction (skin, mucosa, glands, kidney) -> indirectly inc in BP
B2 - dilation (sk. muscle) -> indirectly dec BP
Think fight or flight: need to inc blood flow to sk muscle by directing it away from areas that don't need as much during the "crisis" |
