Examples of epinephrine in the following topics:
-
How the Body Responds to Stress
- The hormones epinephrine (also known as adrenaline) and norepinephrine (also known as noradrenaline) are released by the adrenal medulla.
- Epinephrine and norepinephrine increase blood glucose levels by stimulating the liver and skeletal muscles to break down glycogen, and by stimulating glucose release by liver cells.
- Epinephrine and norepinephrine are collectively called catecholamines.
-
Schachter–Singer Theory of Emotion (Two-Factor Theory)
- In their research, Singer and Schachter injected participants with adrenaline (epinephrine), which causes a number of physiological effects, such as increased blood flow to the muscles and increased heart rate.
-
The Endocrine System
- Epinephrine: also known as adrenaline; comes from the adrenal gland; affects blood pressure and other stress responses.
- Adrenal gland: regulates fluid and sodium balance within the body, and secretes epinephrine ("adrenaline") when the body is under stress, producing the fight-or-flight response.
-
The Endocrine System and Stress
- This causes a negative feedback cycle in which the steroids inhibit the hypothalamus and the pituitary gland, and it also causes the adrenal gland to produce the hormones epinephrine (also known as adrenaline) and norepinephrine.
-
The Endocrine System and Hunger
- However, during fasting, glucagon and epinephrin levels rise and stimulate hunger.
-
Stimulants
- MDMA differs from most stimulants in that its primary pharmacological effect is on the neurotransmitter serotonin rather than dopamine, epinephrine, or norepinephrine.
-
Biology of Emotion
- SNS activation causes the adrenal glands to produce epinephrine (also known as adrenaline), which results in the "fight-or-flight" response.
