29
Q

A

initial inflammatory effects

30
Q

Catecholamines are released from

A

The adrenal medulla

31
Q

Catecholamines

A

Mimic direct sympathetic stimulation
Increases pro inflammatory cytokine production
Increases HR, BP and impairs wound healing

32
Q

a- adrenergic receptors

A

a1 and a2

33
Q

B- adrenergic receptors

A

B1 and B2

34
Q

Neuropeptide Y (NPY)

A

sympathetic neurotransmitter

Growth factor

35
Q

Histamines

A

pro inflammatory
Target mast cells
Induces acute inflammation and allergic reaction while suppressing Th1 and promoting Th2 activity

36
Q

Role of immune system

A

Stress directly related to pro inflammatory
Link between stress, immune function, and disease/ cancer
Immune system affected by neuroendocrinefactors
Stress response decreases T-cell cytotoxicity and B- cell function
