1

Adrenergic receptors are divided into two general categories:

alpha and beta

2

The two adrenergic receptor types are broken down into additional subtypes. name them:

alpha 1 and alpha 2
beta 1 and beta 2

3

these receptors are POSTsynaptic:

alpha 1

4

alpha 1 receptors are located in

smooth muscle throughout the body

5

the most important CV effect of alpha 1 stimulation is:

vasoconstriction

6

stimulation of alpha 1 receptors results in what CV changes?

vasoconstriction resulting in:

- increased PVR
- Increased LV Afterload
- increased arterial BP

7

what does stimulation of alpha 1 do to the lungs?

bronchoconstriction

8

alpha 2 receptors are located primarily on the:

PRE-Synaptic nerve terminals

9

which receptors create a negative feedback loop that inhibits further NE release from the neuron?

alpha 2

10

the alpha 2 receptors create a neg fb look that does what?

inhibits additional NE release from the neuron

11

stimulation of alpha 2 receptors in the CNS results in:

sedation and reduction of sympathetic outflow

-resulting in peripheral vasodilation and lower blood pressure
