Pharm Flashcards
ALPHA 1 RECEPTOR
Tissues - Actions (3)
“Gimme an alpha 1 VID”
(1) Most Vascular smooth muscle- contracts (inc. vascular resistance)
(2) Dilator Pupillary muscle- contracts (myDriasis)
(3) Internal Urethral Sphincter- contracts
ALPHA 2 RECEPTOR
Tissues- Actions (5)
“You’ll find alpha 2 receptors on a PPEAA”
(1) [Adrenergic and cholinergic nerve terminals]- inhibits NTS release–> [CNS-mediated BP DEC]
(2) Platelets- stimulates aggregation
(3) Pancreas- DECREASES Insulin Release
(3) Adipocytes - DEC Lipolysis
(4) Eye - DEC Intraocular pressure
BETA 1 RECEPTOR
Actions (2)
(1) Heart- INC rate and force by [INC [Na+ I(f) channels] in phase 0 of AV node] –> shortens PR interval
(2) JGA cells- Stimulates renin release
BETA 2 RECEPTOR
Tissues-Actions (4)
“B Team Team 2 Rarely Loves Play Time”
(1) Relaxes RUV - (Respiratory, Uterine and Vascular) smooth muscle
(2) Liver- stimulates glycoGenolysis
(3) Pancreatic B cells- stimulates insulin release
(4) Tremor activation by @ [voluntary m. somatic n. terminals]
BETA 3 RECEPTOR Tissues-Actions
Fat cells- stimulates Lipolysis
(B1 and B2 may also contribute)
DOPAMINE 1 RECEPTOR
Tissues-Actions
Renal and other splanchnic blood vessels- vasoDilates (reduces resistance)
D for Dopamine Receptor
DOPAMINE 2 RECEPTOR
Tissues-Actions
Nerve terminals- inhibits adenylyl cyclase
