Cards

Term
Define Anatomy
Definition
The science of the structure of the body and its relationship.
Term
Define Physiology.
Definition
The study of physical and chemical processes involved in the functioning of human body.
Term
Define Metabolism, and describe the two metabolic pathways.
Definition
The sum of all the physical and chemical processes by which living organisms are produced and maintained, and also the transformation by which energy is provided for vital processes and activities.
Term
Define Homeostasis.
Definition
The maintenance of a stable equilibrium in biological system that oppresses external or internal disturbances.
Term
Define Negative Feedback and give an example of it.
Definition
Consists of reducing the output or activity of any organ or system back to its normal range of functioning. A good example of this is regulating blood pressure.
Term
Definite Positive Feedback and give an example of it.
Definition
When a system tends to increase output. The product of a reation influences or increases the forward direction of the system; the presence of a product (or signal) results in an increase in the production. An example would be when a nursing infant's sucking increases the secretion of a milk-releasing hormone in the mother.
Term
Define Incidence.
Definition
The rate at which a certain event occurs (the number of new cases of a specific disease during a particular period of time in a population at risk).
Term
Define Opportunistic Pathogens.
Definition
Any microorganism that produces infection whent he health and immunity of the host is severely weakened.
Term
Define Normal Micro Flora.
Definition
Bacteria that normally and harmlessly inhabits in the human body.
Term
Define Prokaryotes.
Definition
An infectious microorganism that is normally a commensal or does not harm its host but can cause disease when the host's resistance is low. An example are cells that do not have a nucleus, such as bacteria; they are unicellular.
Term
Define Nosocomial Infections.
Definition
Develop in hospitalized patients secondary to patient's original condition.
Term
Define Prodromal Stage.
Definition
The initial appearance of symptoms in the host (early symptoms).
Term
Define Broad Spectrum Antibiotics.
Definition
They are active against gram-negative and gram-positive bacteria.
Term
Define what Macrophages are.
Definition

"Big eaters that engulf"

 

A large phagocytic cell found in stationary form in the tissues or as a mobile white blood cell, especially at sites of infection.

Term
Define Cytokines.
Definition
Intercellular protein messenger molecules that regulate movement, proliferation, and differentiation or immune and other cells.
Term
Define Chemotaxis.
Definition
The attraction of leukocytes to an injurious agent.
Term
Define Major Histocompatibility Complex Molecules.
Definition
Self components the immune system uses to determine self versus non-self.
Term
Define Opportunistic Infections.
Definition
Infections of normal harmless organisms in persons with compromised immune functions.
Term
Describe the acute phase response during an inflammation.
Definition
Fever, skeletal catabolism, increased erythrocyte sedimentation rate - not leucopenia.
Term
Describe AIDS dementia complex.
Definition
Memory loss, difficulty concentrating, euphoria, lethargy.
Term
Describe the "window phase" of HIV infection.
Definition
The time between infection and detectable antibody levels.
Term
Describe HIV Type 2.
Definition
Endemic in West Africa - rarer in other parts of the world.
Term
Describe Neutrophils.
Definition
White blood cells have the greatest rate of increase during a bacterial infection.
Term
Describe what Macrophages do.
Definition
They capture and process antigens, and present them to the lymphocytes.
Term
Describe the makeup of the Immune System.
Definition
Red bone marrow, thymus gland, lymphoid organs, splee, T lymphocytes and B lymphocytes.
Term
Examples of Ectoparasites.
Definition
It's a parasite that can live on humans or animals. They suck your blood, and live on versus in the body. Examples are fleas and lice.
Term
Examples of diseases caused by exotoxins.
Definition
Diptheria.
Term
Examples of active immunity.
Definition
Immunity caused by a response to the exposure to a pathogenic agent or a simulated pathogen, such as a flu vaccine.
Term
Examples of non-specific defenses.
Definition
Skin, mucous membranes, phagocytes, inflammation. NOT antigen tagging.
Term
Symptoms of the acute phrimary infection and primary phase of HIV.
Definition
A mononuvleosis, like syntome with fever, myalgias, malaise, sore throat, nausea, and lethargy.
Term
Symptoms at point in which the immune system is compromised by HIV.
Definition
Malignancies, opportunistic infections, dormant infections surface.
Term
List the levels of structural organization in increasing order.
Definition
Chemical, cellular, tissue, organ, organ system, organismal level.
Term
List the four major components of a negative feedback mechanism.
Definition
Sensor, stimulus, integrator, effector.
Term
Principle of complementarity of structure and function.
Definition
Function always follows structure. Each component of human body is structured to perform a specific function.
Term
Vectors of Infectious Diseases.
Definition
Vectors are the transmitters of disease-causing organisms that carry the pathogens. A vector is an animal, insect, or living organism that can carry and transmit communicable diseases to humans.
Term
Gram staining is used on:
Definition
Defining subcategories of bacteria.
Term
Fungi that reproduce by budding.
Definition
YEAST.
Term
Common symptoms of infectious disease.
Definition
Headache, lethargy, muscular pain.
Term
Class I Major Histocompatibility Complex (MHC) Location.
Definition
Found in all nucleous of the body, red blood cells, found in all nucleated cells in the body, mature RBC's have no nucleus.
Term
Immunoglobulins are produced by:
Definition
B Cells.
Term
Specific Immune Mechanisms include:
Definition
protection afforded by cell mediated immunity.
Term
The most abundant immunoglobulin:
Definition
IgG
Term
Immunoglobulins involved in allergic and hypersensitivity responses:
Definition
IgE
Term
"Master Switch" cell in immune system.
Definition
CD4+ T helper cells
Term
Differentiation of T Lymphocytes.
Definition
this is a process that occurs in the thymus.
Term
Lymphocyte involved in humoral immunity through the production of antibodies:
Definition
B Lymphocytes (not T)
Term
Define clusters of differentiation (CD)
Definition
surface proteins that act as markers of recognition for various T and B cells.
Term
Presence of local heat during the inflammatory response is due to:
Definition
increased local blood flow.
Term
AIDs is caused by
Definition
HIV (Human Immunodeficiency virus)
Term
How HIV is spread
Definition
blood, sexual contact, maternal-placental circulation, and breast milk.
Term
HIV virus directly infects:
Definition
CD4+ lymphocytes
