Q

How are the features of arousal occur?

A

The features of arousal are set in motion by the brain structure called the hypothalamus, when our brain interprets a situation as dangerous, neurotransmitters in the hypothalamus are released, triggering the firing of neutrons through the brain and the release of chemicals throughout the body

Q

What is the endocrine system?

A

The system of glands located throughout the body that help control important activities such as growth and sexual activity. The glands release hormones into the bloodstream and on to the various body organs

Q

What occurs when the sympathetic nervous system is activated?

A

Q

What occurs when the parasympathetic nervous system is activated?

A

Leads to an overall calming effect, the nerve fibres of the autonomic nervous system that help return bodily processes to normal

17
Q

When is the sympathetic nervous system activated?

A

The hypothalamus exists the sympathetic nervous system when we perceive a danger

18
Q

What does the sympathetic nervous system do directly?

A

These nerves may stimulate the organs of the body directly, ex: heart rate

19
Q

What does the sympathetic nervous system do indirectly?

A

The nerves may influence the organs indirectly, by stimulating the adrenal glands

20
Q

What happened when the adrenal glands are stimulated

A

Specifically, when the adrenal medulla is stimulated, the chemicals epinephrine (adrenaline) and norepinephrine (noradrenaline) are released

21
Q

How does epinephrine and norepinephrine work in the sympathetic nervous system?

A

They are NOT neurotransmitters in this case, rather they act as hormones and travel through the bloodstream to various organs and muscles, producing further arousal

22
Q

When is the parasympathetic nervous system activated?

A

When the perceived danger passes, these nerve fibres help return our heart beat and other body processes to normal

23
Q

What is the hypothalamic-pituitary-adrenal pathway?

Endocrine system

A

Stressors cause the hypothalamus to signal the pituitary gland. The pituitary secretes the adrenocorticotropic hormone (ACTH). ACTH stimulates the outer layer of the adrenal glands (adrenal cortex), triggering the release of a group of stress hormones called corticosteroids, including the hormone (cortisol). The corticosteroids travel to various body organs, producing further arousal reactions.

24
Q

What is ACTH?

A

Adrenocorticotropic hormone known as the body’s “major stress hormone”.

25
Q

The systems in relations to individuals

A

Each person has a particular pattern of autonomic and endocrine functioning and so a particular way of experiencing arousal when they confront stressors.

26
Q

What is post traumatic stress disorder?

A

A disorder in which a person experiences fear and related symptoms long after a traumatic event

27
Q

What is a traumatic event?

A

An event in which a person is exposed to actual or threatened death, serious injury, or sexual violation

28
Q

How does PTSD differ from anxiety disorders?

A

Unlike anxiety disorders that are typically triggered by situations that most people would not find threatening, the situations that cause PTSD would be traumatic for almost anyone

29
Q

How does DSM-5 classify acute stress disorder?

A

If the symptoms begin within 4 weeks of the traumatic event and last for less than a month

30
Q

How does DSM-5 classify post traumatic stress disorder?

A

If the symptoms continue longer than a month, the symptoms may begin either shortly after the traumatic event or months of years afterwards

31
Q

How does PTSD differ from acute stress disorder?

A

The onset and the duration is what differs these two diagnosis, otherwise the symptoms are almost identical

32
Q

What is emotional dysregulation / labile mood?

A

a pattern where emotions of anxiety, anger, or depression fluctuate markedly

33
Q

What are symptoms of PTSD?

A

Emotional dysregulation. Hyper-alertness, Easily startled, Have trouble concentrating and Develop sleep problems, Guilt, Recurring thoughts, memories, dreams connected to the event (re-experiencing the event), Avoidance of activities that remind them of the event also avoid related thoughts, feelings, conversation. Reduced responsiveness and dissociation (detached from other people, unresponsive to external stimuli, lose interest in things that once brought enjoyment. Depersonalization, Derealization

34
Q

What is depersonalization?

A

Feeling that their conscious state or body is unreal

35
Q

What is derealization?

A

Feeling that the environment is unreal or strange

36
Q

What is dissociation/psychological separation?

A

Feel dazed, have trouble remembering things

37
Q

What are people who experience symptoms of dissociation and unresponsiveness as part of their stress syndrome labeled by the DSM-5?

A

DSM-5 singles out PTSD with dissociative symptoms as a special subtype of the disorder. This pattern is common among PTSD victims whose traumas involve military combat, sexual abuse, or other forms of physical abuse

38
Q

What most commonly triggers acute stress disorder and PTSD?

A

Combat (shell shock, combat fatigue), natural and accidental disasters including serious car accidents, and abuse and victimization (sexual assault, rape)

39
Q

What is Rape Trauma Syndrome (RTS)?

A

A pattern of problematic physical and psychological symptoms. RTS is a form of PSTD. One-third of rape victims develop PTSD.

40
Q

Other triggers for acute stress disorder and PSTD?

A

terrorism (or threat of terrorism) and Torture (physical, psychological, sexual, through deprivation)

41
Q

What are the biological factors that contribute to PTSD?

A

The brain-body stress pathways, the brain’s stress circuit and inherited predispositions
