Q

What are the different heart diseases / heart attacks?

A

A
  • CNS (brain and spinal cord) and PNS (afférent and efferent)
    afferent
    -somatic SN and visceral SN.

Efferent

  • autonomic N.S (automatic)
  • somatic N.S (voluntary)

Autonomic has:
- parasympathetic and sympathetic

154
Q

What is the role of parasympathetic NS?

A

  • slows metabolism and restores energy
  • in control when relaxed
  • aids in digestion, storing food, promoting growth
155
Q

157
Q

What are examples of effects of sympathetic?

A
  • dilates pupils
  • increase HR
  • dilate bronchi
  • stops digestion
  • relaxes bladder (why want to pee when stressed)
158
Q

What is the role of the endocrine system?

A

Is a target of the Sumpathetic N.S

  • is a system of glands/tissues and cells that secrete hormones and other chemical messenger in blood stream that influence metabolism and processes
  • release from adrenal gland (cortisol, epinephrine, NE)
  • helps prepare body
159
Q

Where is ACTH released from?

A

Pituitary gland and informs adrenal cortex to release cortisol

160
Q

What is the fight to flight reaction?

A
  • Defense reaction that prepare for conflict by triggering hormonal, CV, metabolic and other changes
161
Q

What are the fight or flight pathways?

A

Endocrine:
Stressor -> hypothalamus -> pituitary gland -> ACTH -> adrenal glands

NS pathway:
Stressor -> brai > autonomic NS -> adrenal gland

162
Q

D- Tends towards neg emotional state (anxiety, depression) avoids socialization. Worry of others

171
Q

What is hardiness?

A
  • Particular form of optimism
  • one sees challenges as opportunity to grow and learn

Q

what is the general adaptation syndrome (GAS)?

A
  • developper by Hans Selye
  • used to describe a universal/predictable response to all stressors
  • can be applied to Eustress and distress
  • has three stages
177
Q

What are the 3 stages of the GAS?

A

Stage 1: alarm stage

  • activation of sympathetic and endocrine system
  • fight to flight reaction
  • body is susceptible to disease and injury

Stage 2: resistance or adaptation stage

  • body develop new level of homeostasis when prolonged stress
  • more resistant to disease/jury than normal

Stage 3: exhaustion
- if stressor persist or too many stressors will result in exhaustion

178
Q

What is allostatic load?

A
  • long term wear and tear of stress response
  • is the increase susceptibility to disease after repeated prolonged stress -> due to effect of stress response itself
  • depends on many factors (genetic, life experiences, emotional/behavioural response)
179
Q

A high allostatic load may be due to?

A
  • frequent stressor
  • poor adaptation to common ones
  • inability to shut down stress response
