B1: Physiological Responses To Stress: Sam system

Question 1

What does SAM stand for

Answer 1

Sympathomedullary

Question 2

How does the SAM system work

Answer 2

1. Detecting Stress: When a stressor is perceived, the hypothalamus signals the body to prepare for action by activating the sympathetic branch of the autonomic nervous system (ANS).
   
   2. Adrenaline Release: The sympathetic system triggers the adrenal medulla (part of the adrenal glands) to release adrenaline and noradrenaline into the bloodstream.
   3. Body’s Response: These hormones circulate in the blood and prepare the body by increasing heart rate, diverting blood to the muscles, and triggering other physical changes (e.g., sweating) to help fight or flee.
   4. Calming Down: Once the threat passes, the parasympathetic branch of the ANS takes over, calming the body and returning it to a relaxed, rest-and-digest state

Question 3

What does the SAM system control

Answer 3

The body’s immediate response to an acute stressor (flight or fight response )

Question 4

What does “sympatho” in SAM system refer to

Answer 4

The sympathetic branch of the autonomic nervous system which triggers automatic response

Question 5

What does’‘medullary” un 8AM system refer to

Answer 5

The adrenal medulla which. Releases adrenaline. And noradrenaline

Question 6

What does adrenaline and noradrenaline do

Answer 6

They stimulate target organs increase heart rate diverting blood to muscles and cause sweating

Question 7

What happens to the SAM system when a threat stops

Answer 7
