52
nociceptors
- sense injury in response release messengers conducted to spinal cord where passed directly to reticular formation
- identify site of injury and send message down spinal cord
53
nociception
- a-delta fibres: respond to mechanical or thermal pain, small myelinated, 1st sharp pain, affects sensory aspects opens gate
- c-fibres: transmit dull, aching pain, unmyelinated, motivational and affective elements of pain, opens gate
- a-beta fibres: respond to position and vibration, large myelinated suppress pain by transmitted c-fibres, close gate
54
factors that open or close pain gate
- physical: open (inappropriate activity level) close (meds, counter stimulation)
- emotional: open (anxiety, depression) close (relaxation)
- cognitive: open (boredom) close (distraction)

Estrogen provides protective effects by increasing HDL and reducing SNS arousal.
60
Why does CHD risk increase after menopause?
After menopause, estrogen levels drop, increasing the risk of cardiovascular disease.
61
How are anger and hostility related to CHD?
Hostile individuals are at higher risk of CHD due to increased cardiovascular reactivity.

85
What health complications arise from diabetes?
Blindness, kidney failure, foot ulcers, eating disorders, and nervous system damage.
86
How does stress affect diabetes?
Stress increases sympathetic nervous system reactivity, worsening diabetes management.
87
What are key strategies for diabetes management?
Reducing sugar intake, maintaining healthy weight, exercising, and behavioral interventions.
88
How does diet contribute to diabetes?
High sugar and refined carbohydrate intake lead to obesity, insulin resistance, and metabolic syndrome.
89
What is insulin resistance?
A condition where cells fail to respond to insulin properly, leading to high blood sugar levels.
90
Why are carbohydrates criticized in modern diets?
Excess carbohydrate intake contributes to obesity, diabetes, and metabolic syndrome.
91
What role does metabolic syndrome play in health?
It links obesity, insulin resistance, hypertension, and heart disease to increased mortality risk.
