It initiates the flight or fight response within the body. Epinephrine is just another word for adrenaline. It causes your heart to beat rapidly.
The secretion of epinephrine by the adrenal medulla is primarily mediated by nicotinic acetylcholine receptors. These receptors are activated by acetylcholine released from preganglionic sympathetic fibers. This stimulation triggers the adrenal medulla to release epinephrine (and norepinephrine) into the bloodstream, contributing to the body's fight-or-flight response.

sympathetic nerves
Sympathetic nerves: prepare the body for emergencies and stress by increasing the breathing rate, heart rate, and blood flow to muscles. These nerves become aroused as part of the fight-or-flight response, which is the body's natural reaction to real or imaginary danger.
Which body change is not triggered by epinephrine is slowing of breathing.
Adrenaline or epinephrine is a hormone released from the adrenal glands and its major action, together with noradrenaline, is to prepare the body for fight or flight.
epinephrine is produced by your body, and is also known as adrenaline.
Adrenaline (epinephrine) is a hormone released from the adrenal glands and its major action, together with noradrenaline, is to prepare the body for "fight or flight".
increased heart rate, elevated blood pressure, redirection of blood flow to vital organs, and dilation of airways to improve oxygen delivery to tissues. Epinephrine helps prepare the body to respond to the state of reduced blood flow.
Adrenaline (epinephrine) is a hormone released from the adrenal glands and its major action, together with noradrenaline, is to prepare the body for fight-or-flight.
Epinephrine is commonly known as the "fight or flight" hormone, released in response to stress or danger. While it can increase arousal and prepare the body for action, it is not specifically referred to as the "anger hormone." Anger is a complex emotional response involving various neurotransmitters and hormones in the brain.
The adrenal glands are associated with the production of epinephrine and norepinephrine, which are both involved in the body's "fight or flight" response to stress. These hormones help prepare the body for intense physical activity by increasing heart rate, dilating airways, and mobilizing energy stores.
