|
if there is a chronic exposure to antagonist what happens?
|
upregulation of receptors
|
|
|
if there is a chronic exposure to agonist what occurs?
|
down regulation of receptors
|
|
|
what PS act on the iris sphincter muscle?
|
M3 and ACH and Gq
|
|
|
What SS act on the iris radial muscle?
|
alpha 1 and NE and Gq
|
|
|
what are 2 ways to induce mydriasis (dialated pupil)?
|
M3 antagonist and alpha 1 agonist
|
|
|
How do PS act on the ciliary muscle?
|
they cause it to contract via M and ACH to relax suspensory ligs and rleax lens. This allows for near vision.
|
|
|
What happens if the PS to ciliary muscle are blocked?
|
The ciliary muscle relaxes, tightens the ligs, and stretches the lens.
|
|
|
will and alpha 1 agonist cause blurred vision?
|
No, there are no alpha 1 receptors on ciliary muscle, only on iris radial SM.
|
|
|
what receptor types are found within bronchial SM
|
M3 and Beta 2
|
|
|
Bronchial gland receptors?
|
M3
|
|
|
what does Beta 2 respond to?
|
epi
|
|
|
what is a pharmalogical antagonist?
|
something that opposes the undesired motion from a different receptor.
|
|
|
what PS receptors are found in the stomach? sphincter? intestines?
|
M3,M,M3
|
|
|
What SS are found in the stomach? Sphincter? intestine?
|
none, alpha 1, alpha2 and beta2
