Chapter 3 Stress and Illness/Disease Flashcards
Hot reactors
people who react to stress with an all-out physiological reaction
tend to suffer from chronic anger or anxiety, which leads to high blood pressure and heart attacks known as hate attacks.
psychosomatic, also known as ____ are ….
also known as psychophysiological
conditions that have both a mind and body component
a common cold may be a function of psychological stress which decreases the effectiveness of the immunological system and results in the body being more vulnerable to cold viruses
psychogenic
a physical disease caused by emotional stress without a microorganism involved
example - asthma
somatogenic
a psychosomatic disease that results from the mind increasing the body’s susceptibility to disease-causing microbes or natural degenerative processes
example - cancer and rheumatoid arthritis
psychoneuroimmunology
the study of the illness-causing and healing effects of the mind on the body
Was named by Robert Ader.
phagocytes
a type of white blood cell whose purpose is to destroy substances foreign to the body
b cells
a type of lymphocyte that produces antibodies that travel to the site of invasion and either neutralize the enemy or tag it for attack by other cells and chemicals
phagocytes, T cells, and B cells all share one function …to what?
to identify and destroy all substances foreign to the body
Macrophages
these are the most important phagocytes
they surround and engulf invading substances while summoning helper T cells.
helper T cells
a type of lymphocyte
identify the invader and stimulate the multiplication of killer T cells and B cells.
killer T cells
a type of lymphocyte
puncture the membranes of body cells invaded by the foreign substance, thereby killing the cell and substance
suppressor T cells
cells that halt the immune response
memory t and b cells
cells left in the bloodstream and the lymphatic system to recognize and respond to future attacks to the body by the same invader
Hans Eysenck presents evidence for what kinds of personalities?
cancer prone
unassertive, overpatient, avoiding conflicts, and failing to express negative emotions
angry, hostile, aggressive
hypercholesterolemia
is a condition characterized by high levels of cholesterol in the blood
cholesterol
a waxy, fat like substance that is produced in the body and obtained from foods that come from animals ( egg yolks, meat, poultry, fish and dairy products)
the body needs cholesterol to build cell membranes, make certain hormones, and produce compounds that aid in fat digestion
what happens when you get a buildup of cholesterol?
forms clumps (plaque) that narrow and harden the artery walls
as the clumps get bigger, they can clog the arteries and restrict the flow of blood to the heart. The buildup of plaque in coronary arteries causes a form of chest pain called angina, and greatly increases a person’s risk of having a heart attack
how is cholesterol carried?
in small packages called lipoproteins. The small packages are made of fat (lipid) on the inside and proteins on the outside
low density lipoprotein (LDL)
sometimes termed bad cholesterol
too much LDL leads to a clogging of arteries and is related to the development of coronary heart disease
high density lipoprotein (HDL)
sometimes termed good cholesterol
HDL carries cholesterol from other parts of your body back to your liver. the liver helps to remove cholesterol from the body thereby lowering the chances of developing coronary heart disease
Friedman, Rosenman, and Carroll conducted an investigation of the relationship between what two things?
stress and serum cholesterol
hypertension
high blood pressure
is excessive and damaging pressure of the blood against the walls of the arterial blood vessels.
Blood pressure is measured with a …?
sphygmomanometer - an instrument consisting of an inflatable cuff placed around the upper arm and a stethoscope.
systolic blood pressure
The cuff cuts off the blood flow in the brachial artery until it is deflated to the point where the blood pressure forces the blood through
-pressure of blood as it leaves the heart
120 mm Hg is normal
diastolic blood pressure
at the point where the cuff is deflated further and the blood is not impeded at all, another measure is taken.
-pressure of the blood against the arterial walls when the heart is relaxed
80 mm Hg is normal
what is considered high blood pressure
systolic pressure greater than 140 mm Hg
diastolic pressure greater than 90 mm Hg is hypertension
blood pressure for elderly
140/90
What are the causes for hypertension?
excessive sodium (salt) intake - 5,000 mg daily
kidney disease - too narrow an opening in the aorta (main blood vessel through which blood exits the heart)
Cushing’s syndrome (over secretion of cortisol hormones)
obesity
oral contraceptives
