NEET PG DENTAL EXAM

Detailed explanation-1: -After the amygdala sends a distress signal, the hypothalamus activates the sympathetic nervous system by sending signals through the autonomic nerves to the adrenal glands. These glands respond by pumping the hormone epinephrine (also known as adrenaline) into the bloodstream.

Detailed explanation-2: -Adrenaline is produced in the medulla in the adrenal glands as well as some of the central nervous system’s neurons. Within a couple of minutes during a stressful situation, adrenaline is quickly released into the blood, sending impulses to organs to create a specific response.

Detailed explanation-3: -If the adrenals produce adrenaline without the threat of danger, an adrenaline rush has the potential to ramp up the sympathetic nervous system and make you feel anxious. You can generally self-manage an overactive sympathetic nervous system through deep breathing or other stress-reducing activities.

Detailed explanation-4: -The sympathetic nervous system releases norepinephrine (NE) while the parasympathetic nervous system releases acetylcholine (ACh).
