EPPP Psychology

Answer: C - The adrenal gland is the physiological structure that produces the fight-or-flight neurotransmitter epinephrine. Epinephrine is a hormone and a neurotransmitter that is produced in the adrenal glands. Epinephrine has a number of functions in the body. It raises the heart rate and increases the oxygen and sugar supply to the brain and muscles. These effects on the body are designed to help a person deal with a state of arousal due to danger, for example. If epinephrine is high for too long, it can cause damage to the organs from the continued rise in heart rate and increase in sugar.
