• Alpha 1 and 2

• Beta 1 and 2

What are the (4) Adrenergic Receptors?

Alpha 1

IDENTIFY THE ADRENERGIC RECEPTORS:

• Vasoconstriction

• Increase peripheral resistance (blood flow)

• Increase blood pressure

• Mydriasis

• Increase closure bladder sphincters

Alpha 2

IDENTIFY THE ADRENERGIC RECEPTORS:

• Inhibits norepinephrine release

• Inhibits acetylcholine release

• Inhibits insulin release

Beta 1

IDENTIFY THE ADRENERGIC RECEPTORS:

• Increase heart rate

• Increase lipolysis

• Increase myocardial contractility

• Increase renin

Beta 2

IDENTIFY THE ADRENERGIC RECEPTORS:

• Vasodilation

• Decrease peripheral resistance (blood flow)

• Bronchodilation

• Increase glycogenolysis (muscle, liver)

• Increase glucagon release

• Relaxes uterine smooth muscle

Mydriasis

This condition is when the pupil is dilated and unresponsive to light. It stays enlarged and fixed, regardless of light levels, due to a drug, disease, injury or other cause.

Lipolysis

This is the breakdown of fats by enzymes and water in adipose tissue.

Myocardial

A heart attack, happens when a part of the heart muscle doesn’t get enough blood. Coronary artery disease (CAD) is the main cause of heart attack.

Renin

This is an enzyme that helps manage your blood pressure and maintain healthy levels of sodium and potassium in your body.

Glycogenolysis

This is the breakdown of glycogen into glucose for energy.

Alpha 1

IDENTIFY THE ADRENERGIC RECEPTORS:

NE > E

Alpha 2

IDENTIFY THE ADRENERGIC RECEPTORS:

E > NE

Beta 1

IDENTIFY THE ADRENERGIC RECEPTORS:

E = NE

Beta 2

IDENTIFY THE ADRENERGIC RECEPTORS:

E » NE
