- generates a cascade of biochemical events which
affect:

emotion in two hours
preceding an MI

1. Sympathetically mediated increase in –
Heart rate
Blood pressure

Increase in African Zulus moving from rural to urban centers
Chronic Stress: Chronic Stress Unresolved, repetitive stress may lead to:
Depression
Anxiety
Associated with:
chronic pain (Turner 1989)
susceptibility to common cold (Cohen 1991)

Slide45: hypothalamic–pituitary–adrenal (HPA) axis and the autonomic nervous system. The stress system influences other endocrine systems (i.e., those controlling gonadal, thyroidal, and growth functions) and exerts complex effects on the immune/inflammatory reaction. The principal CNS centers of the stress system are the corticotropin-releasing hormone (CRH)/arginine vasopressin (AVP) and locus ceruleus–norepi-nephrine neurons of the hypothalamus and brainstem, respectively, which regulate the HPA axis and the sympathetic nervous system. The end hormones of these systems, glucocorticoids and the catecholamines, act to maintain behavioral, cardiovascular, metabolic, and immune homeostasis during stress.1,2,5,6 and 7,7a
