ANS Intro Flashcards
M3
exocrine glands, smooth muscle, endothilium
MOA: PLC -> IP3 and DAG -> Calcium and Protein Kinase (->depol)
MOA same as M1
M1 receptor
CNS and SWEAT gland
MOA: increase phophlipase C (PLC) -> produces IP3 and DAG -> increase Ca2+ and activate Protein Kinases (-> depolarizes cell?)
M2
heart, smooth m (like M3), presynaptic neurons (decrease NE)
MOA: decrease Adenylyl cyclase -> open K chanels -> HYPERpolarize neuronal cell
Pre-synaptic M2: decrease NE
Nicotinic Nn
Post-GANGLIONIC neurons (2nd neuron)
Pre-synaptic terminals
Nicotinic Nm
Skeletal Muscle
MOA: bind ACh -> open Na channels -> depolarize cell
Alpha 1
smooth m (like (M2-hrt,pre-syn and M3-exocrine, endothilium)
MOA: Gq, increase PLC -> IP2 and DAG -> Ca2+ - > depol cell
(MOA like M1 (sweat) and M3)
Alpha 2
pre-synaptic terminals (like M2), platelets, lipocytes, smooth m (like Alpha1, M3 and M2)
MOA like M2: Gi, decrease Adenylyl Cyclase -> open K channels -> HYPERpol
Pre-syn Alpha 2: decrease NE (like M2)
Beta 1
heart (like M2), pre-synaptic (like M2) and post-syn
MOA: Gs, increase Adenylyl Cyclase
Pre-syn B: increase NE
Beta 2
heart (like M2), post-syn (like B1), smooth m (like A1, M2, M3), bronchioles
Beta 3
lipocytes, lipilysis
MOA: increase Adenyly cyclase
D1 and D5
Brain, renal vasculature
MOA: increase Adenylyl (Or Adenylate) cyclase
D2, D3, D4
Brain (like D1 and D5), various tissues
MOA: decrease Adenylate Cyclase (opposite MOA of D1 and D5)
pre-syn M2 and A2
decrease NE
Pre-syn Beta
increase NE as opposed to pre-syn M2 and A2
