L5 - Fight or Flight

Question 1

what role does the SYMPATHOMEDULLARY PATHWAY play in the FIGHT OR FLIGHT RESPONSE?

Answer 1

the SYMPATHETIC NERVOUS SYSTEM (SNS) is triggered by the HYPOTHALAMUS

The HYPOTHALAMUS also SENDS A SIGNAL to the ADRENAL MEDULLA (part of the adrenal glands), which responds by RELEASING A HORMONE CALLED ADRENALINE into the bloodstream

Question 2

what role does ADRENALINE play in the FIGHT OR FLIGHT RESPONSE?

Answer 2

ADRENALINE will INCREASE HEART RATE, CONSTRICT BLOOD VESSELS, INCREASE RATE OF BLOOD FLOW, RAISE BLOOD PRESSURE, DIVERT BLOOD AWAY FROM THE SKIN, KIDNEYS and d DIGESTIVE SYSTEM, INCREASE BLOOD SUPPLY to the BRAIN and SKELETAL MUSCLES, and INCREASE RESPIRATION and SWEATING

All of this PREPARES THE BODY for ACTION and FIGHT OR FLIGHT by INCREASING BLOODY SUPPLY , and therefore OXYGEN TO SKELETAL MUSCLES for PHYSICAL ACTION and INCREASING OXYGEN to the brain for RAPID RESPONSE PLANNING

Question 3

what role does the PARASYMPATHETIC NERVOUS SYSTEM play in the FIGHT OR FLIGHT RESPONSE?

Answer 3

When the THREAT HAS PASSED the PARASYMPATHETIC NERVOUS SYSTEM DAMPENS DOWN THE STRESS RESPONSE.

It SLOWS DOWN THE HEARTBEAT and REDUCES BLOOD PRESSURE.

DIGESTION RESTARTS, which is STOPPED WHEN THE SNS IS ACTIVE

Question 4

+ MAKES SENSE (EVALUATION OF THE FIGHT OR FLIGHT RESPONSE)

Answer 4

+ the FIGHT OR FLIGHT RESPONSE MAKES SENSE from an EVOLUTIONARY PSYCHOLOGY POINT OF VIEW because it would have HELPED THE INDIVIDUAL TO SURVIVE by FIGHTING or FLEEING A THREAT

Question 5

+ ESSENTIAL (EVALUATION OF THE FIGHT OR FLIGHT RESPONSE)

Answer 5

+ studies SUPPORT THE CLAIM that ADRENALINE IS ESSENTIAL in PREPARING THE BODY FOR STRESS

People who have MALFUNCTIONING ADRENAL GLANDS DO NOT have a NORMAL FIGHT OR FLIGHT RESPONSE TO STRESS

Question 6

• GRAY (EVALUATION OF THE FIGHT OR FLIGHT RESPONSE)

Answer 6

• GRAY states that the FIRST REACTION TO STRESS is NOT TO FIGHT OR FLIGHT but FREEZE

This involves the person STOPPING, LOOKING and LISTENING and BEING HYPER VIGILANT TO DANGER

Question 7

• TAYLOR (EVALUATION OF THE FIGHT OR FLIGHT RESPONSE)

Answer 7

• TAYLOR found that FEMALES TEND AND BEFRIEND in TIMES OF STRESS

TEND AND BEFRIEND refers to the PROTECTION of OFFSPRING (tend) and SEEKING OUT SOCIAL GROUPS for MUTUAL DEFENCE (befriend)

Women have the HORMONE OXYTOCIN, which means they are MORE LIKELY TO STAY and PROTECT THEIR OFFSPRING

Question 8

• VON DAWANS (EVALUATION OF THE FIGHT OR FLIGHT RESPONSE)

Answer 8

• VON DAWANS has found that EVEN MALES ALSO TEND AND BEFRIEND

For example, during the 2001 SEPTEMBER 11th TERRORIST ATTACKS both MALES AND FEMALES showed TEND AND BEFRIEND as they TRIED TO CONTACT LOVED ONES and HELP ONE ANOTHER
