Video Summary
Adrenergic receptors are proteins found on the surface of cells that respond to the hormone adrenaline (epinephrine). There are three types of adrenergic receptors - alpha, beta, and gamma. Each type responds to a different set of chemical signals from adrenalin.
When adrenaline binds to its receptor, it triggers a series of biochemical reactions inside the cell that result in increased heart rate, increased blood pressure, and other effects that prepare the body for physical activity.
