Which of the following is not a cellular function?
Reproduction
Combustion
Absorption
Excretion - combustion
Which if the following can cause edema?
Decreased capillary hydrostatic pressure
Increased lymphatic pressure
Increased plasma pressure
Decreased capillary permeability - Increased lymphatic pressure
Which of the following best describes the result of cellular reproduction?
During anaphase, the centromeres come together.
During telophase, a nuclear membrane is formed around 23 chromosomes.
Two diploid cells, called daughter cells, are produced.
Cellular reproduction has a long interphase. - Two diploid cells, called daughter cells, are
produced.
What is an example of both hyperplasia and hypertrophy?
Liver enlargement after partial removal
Uterine enlargement due to pregnancy
Cardiac enlargement due to hypertension
Muscle enlargement due to work - Uterine enlargement due to pregnancy
deifine hyperplasia & hypertrophy - Hyperplasia is the increase in the number of cells of an
organ or tissue, while hypertrophy is the enlargement of the cells of a given organ or tissue
without a change in the number of cells. Muscle cells grow and enlarge (hypertrophy) in
response to increased work or stress from exercise or increased cardiovascular pressures.
When a liver is damaged or part of it is removed, it is the one internal solid organ capable
of regeneration to repair itself creating more cells (hyperplasia). During pregnancy, the
uterus must both grow to create more cells and enlarge those existing cells in preparation
for the support of a fetus.
Previousquestion
What regulates the sodium balance?
Chloride
Aldosterone
Renin
Potassium - aldosterone
,When in excess, what do buffers absorb?
Oxygen
Hydrogen
Potassium
Bicarbonate - Hydrogen; Think Chem!. H+ is acid
describe translation and transcription - Translation refers to this process. Transcription is
another process in which RNA is synthesized
What is the recurrence rate for autosomal dominant disease? - 50% for a couple in which
one or both partners are affected by the disease, the chance of each child being
heterozygous affected is 50%.
Which of the following statements is true about autosomal recessive disease?
It affects only women.
It affects both men and women equally.
It affects men and women, but men more often.
It affects men only. - men and women equal
What is the proportion of the population affected by a disease at the specific point in time?
Relative risk
Incidence rate
At-risk rate
Prevalence rate - prevalence
Incidence rate refers to how many new cases there are of a disease within a period of time
divided by the number of the population's individuals. The prevalence rate is affected by
the incidence rate and how long the affected patients survive. Risk factor is anything that
could lead to disease. Relative risk is the measure of a risk factor effect.
Previousquestion
Which action is the purpose of the inflammatory - To destroy foreign, invasive
microorganisms
What causes edema that occurs during the inflammatory process? - Increased pressure in
the vasculature secondary to the vasodilatory effects of inflammation will result in the
leakage of fluid into third spaces (i.e., edema).
In what structure do B lymphocytes mature and become B cells? - BONE MARROW (B for B)
The bone marrow is where immature immune cells, such as B and T lymphocytes, reside to
mature into B cells. After this maturation process, these cells migrate to other organ sites
such as the thyroid, spleen, and thymus to enter their final stages of differentiation and
development.
, Which type of immunity occurs when antibodies are transferred from donor to recipient? -
passive acquired immunity
Active immune processes are the self-originating processes of the immune system that
occur from (acquired) or without (innate) prior exogenous simulation or exposure to
foreign antigens. Passive immunity is stabilized. Existing immune responses that are
present with or without simulation can arise or be created from oneself (innate) or
acquired from an outside source (e.g. donor antibodies).
What does T-cell activity cause in older adults? - Increased susceptibility for infection
As the human body ages, the immune system's effectiveness to coordinate responses to
pathogens and other foreign antigens wanes and the risk for disease increases.
What is a dermatitis caused by prolonged exposure to chemicals such as acids or soaps also
known as?
Stasis dermatitis
Stopic dermatitis
Irritant contact dermatitis
Allergic contact dermatitis - Irritant contact dermatitis
Prolonged, superficial skin exposure to foreign irritants (e.g., acids or soaps) is a
manifestation of an innate, local inflammatory response. The conditions of allergic, stasis,
and atopic dermatitis involve more systemic processes of the immune system and
vasculature.
Which of the following is a self-limiting disease associated with Herpes type viruses and a
herald patch? - Pityriasis rosea
What is a furuncle? - n infection of the hair follicle that extends to the surrounding tissue
What type of lesion may be malignant in the form of squamous cell carcinoma (SCC)?
Keratoacanthoma
Seborrhaic keratosis
Nevi
Actinic keratosis - Actinic keratosis
What type of abnormal cell growth does carcinoma refer to? - Carcinoma refers to
dysplastic epithelial cells that have penetrated the entire thickness of the epithelium into
the basement membrane.
What is a characteristic of a malignant tumor? - Absence of normal tissue organization
Healthy tissue is made up of non-cancerous cells that are well-differentiated, connected via
a well-organized stroma and that stay put. Malignant tumors lack those characteristics as
well as normal tissue organization.
