Flashcards in Cardiovascular Pharmacology Deck (11)
Adrenergic receptors are divided into two general categories:
alpha and beta
The two adrenergic receptor types are broken down into additional subtypes. name them:
alpha 1 and alpha 2
beta 1 and beta 2
these receptors are POSTsynaptic:
alpha 1 receptors are located in
smooth muscle throughout the body
the most important CV effect of alpha 1 stimulation is:
stimulation of alpha 1 receptors results in what CV changes?
vasoconstriction resulting in:
- increased PVR
- Increased LV Afterload
- increased arterial BP
what does stimulation of alpha 1 do to the lungs?
alpha 2 receptors are located primarily on the:
PRE-Synaptic nerve terminals
which receptors create a negative feedback loop that inhibits further NE release from the neuron?
the alpha 2 receptors create a neg fb look that does what?
inhibits additional NE release from the neuron
