During periods of stress, such as preparing to run in a race, the brain signals the adrenal glands to produce epinephrine or "adrenaline". Epinephrine increases the rate in which the heart beats. The increased cardiac output supplies more oxygen to the muscles, putting the body in a heightened state to react. As a longer term response to stress, cortisol is secreted by the adrenal glands, promoting the release of energy.

What else can I help you with?
Can you use epinephrine for working out?
That would be a dangerous thing to do. Your heartbeat naturally increases as you exercise. Epinephrine is a potent drug and can be fatal if used improperly.
Who control the secretion of epinephrine and norepineprine by the adrenal glands?
Control of secretion of epinephrine and norepinephrine is regulated primarily by descending sympathetic signals in response to stress, including exercise, hypoglycemia, and hemorrhagic hypovolemia
Which is the neurotransmitter for the sympathetic nervous sytem that increases the heart rate to prepare for exercise of the fight or flight response?
epinephrine
Adrenal medulla produces what large amounts of the hormone?
epinephrine and norpepinephrine
What are the two neurohormones found in sympathetic or adrenergic nerves?
Epinephrine or adrenaline, and non epinephrine or noradrenaline.
What would cause fast pulse in or around ribcage?
Besides certain chemicals (such as epinephrine), fast pulse will often come from excitement, fear, nervousness, or exercise.
What is the first drug of choice for acute heart failure?
Often epinephrine is given.epinephrine
Which gland release epinephrine and when is epinephrine released circumstances?
Epinephrine, also known as adrenaline, is released by the adrenal medulla, which is part of the adrenal glands located on top of each kidney. This hormone is typically released in response to stress or danger, as part of the body's "fight or flight" response, during situations such as physical threats, intense exercise, or emotional stress. The release of epinephrine leads to increased heart rate, elevated blood pressure, and enhanced energy availability, preparing the body to react quickly.
Is epinephrine water soluble?
Yes, epinephrine is water soluble.
When a person is physically stressed what hormone is released quickly to stimulate an increase in blood glucose concentration?
is it epinephrine?
What distinguishes a vial of lidocaine with epinephrine from a vial without epinephrine?
if lidocaine is represented by a percentage(1% or 2%) followed by a 1:100,000 then it contains epinephrine. the 1:100,000 is the concentration of epinephrine in the medication.
Does post ganglionic fibers release epinephrine?
No, postganglionic fibers release norepinephrine, not epinephrine. Epinephrine is released by the adrenal medulla.
