People diagnosed with neurofibromatosis have varying degrees of the condition
because of which genetic principle?

What is the most common cause of Down syndrome?
a. Paternal nondisjunction
b. Maternal translocations
c. Maternal nondisjunction
d. Paternal translocation -Correct Answer ✔C
What does activation of the classical pathway begin with? a. Viruses
b. Antigen-antibody complexes c. Mast cells
d. Macrophages -Correct Answer ✔B.
Activation of the classical pathway begins only with the activation of protein C1 and is
preceded by the formation of a complex between an antigen and an antibody to form an
antigen-antibody complex (immune complex). Infection with a virus can lead to the start
of the inflammatory process, but is not the specific activation factor. Mast cells release
the contents of their granules to initiate synthesis of other mediators of inflammation
among other actions. Macrophages are one cell type involved in phagocytosis.
In the coagulation (clotting) cascade, the intrinsic and the extrinsic pathways converge
at which factor?
a. XII
b. VII
c. X
d. V -Correct Answer ✔C. The coagulation cascade consists of the extrinsic and intrinsic
pathways that converge only at factor X.
What effect does the process of histamine binding to the histamine-2 (H2) receptor have
on inflammation?
a. Inhibition
b. Activation
c. Acceleration
d. Termination -Correct Answer ✔A. Binding histamine to the H2 receptor is generally
antiinflammatory because it results in the suppression of leukocyte function. Binding to
H2 receptors does not cause activation, acceleration, or termination of the inflammatory
process.

Frequently when H1 and H2 receptors are located on the same cells, they act in what
fashion?
a. Synergistically
b. Additively
c. Antagonistically
d. Agonistically -Correct Answer ✔C. Both types of receptors are distributed among
many different cells and are often present on the same cells and may act in an
antagonistic fashion. For instance, neutrophils express both types of receptors, with
stimulation of H1 receptors resulting in the augmentation of neutrophil chemotaxis and
H2 stimulation resulting in its inhibition. The two receptors do not act synergistically,
additively, or agonistically.
What is the inflammatory effect of nitric oxide (NO)?
a. Increases capillary permeability, and causes pain b. Increases neutrophil chemotaxis
and platelet aggregation
c. Causes smooth muscle contraction and fever
d. Decreases mast cell function, and decreases platelet aggregation -Correct Answer
✔D. Effects of NO on inflammation include vasodilation by inducing relaxation of
vascular smooth muscle, a response that is local and short-lived, and by suppressing
mast cell function, as well as platelet adhesion and aggregation. NO does not increase
capillary permeability and cause pain, increase neutrophil chemotaxis and platelet
aggregation, or cause smooth muscle contraction and fever.
Which cytokine is produced and released from virally infected host cells?
a. IL-1
b. IL-10
c. TNF-α
d. IFN-α -Correct Answer ✔D. Only interferons (IFNs) are produced and released by
virally infected cells in response to viral double-stranded ribonucleic acid (RNA). IFN-α
and IFN-β induce the production of antiviral proteins, thereby conferring protection on
uninfected cells. IFN-α or IFN-β is released from virally infected cells and attaches to a
receptor on a neighboring cell. IFNs also enhance the efficiency of developing an
acquired immune response. IL-1 is a proinflammatory interleukin. IL-10 plays a critical
role in wound healing. TNF has several systemic effects but is not released from virally
infected host cells.
What does the phagosome step result in during the process of endocytosis?
a. Microorganisms are ingested.
b. Microorganisms are killed and digested.
c. Phagocytes recognize and adhere to bacteria.
d. An intracellular phagocytic vacuole is formed. -Correct Answer ✔D. Small
pseudopods that extend from the plasma membrane and surround the adherent
microorganism, forming an intracellular phagocytic vacuole or phagosome, carry out
engulfment (endocytosis). The membrane that surrounds the phagosome consists of
inverted plasma membrane. After the formation of the phagosome, lysosomes

converge, fuse with the phagosome, and discharge their contents, creating a
phagolysosome.
When cellular damage occurs and regeneration is minor with no significant
complications, what is the process of returning the cells to preinjury function referred to
as?
a. Restoration
b. Resolution
c. Regrowth
d. Replacement -Correct Answer ✔B If damage is minor with no complications and
destroyed tissues are capable of regeneration, then returning the injured tissues to an
approximation of their original structure and physiologic function is possible. This
restoration is called resolution. Resolution is the restoration of the original tissue
structure and function. Regrowth and replacement are not part of resolution.
How does the B-cell receptor (BCR) complex function?
a. Communicating information about the antigen to the helper T cell
b. Secreting chemical signals to communicate between cells
c. Releasing histamine and other vasoactive substances
d. Communicating information about the antigen to the cell nucleus -Correct Answer
✔D. The role of the BCR is to recognize the antigen; however, unlike circulating
antibodies, the receptor must communicate that information to the cell's nucleus. The
BCR does not communicate information about the antigen to the helper T cell or secrete
chemical signals to communicate between cells. The release of histamine and other
vasoactive substances is part of inflammation, not adaptive immunity.
When antibodies are formed against red blood cell antigens of the Rh system, how are
the blood cells destroyed?
a. Complement-mediated cell lysis
b. Phagocytosis by macrophages
c. Phagocytosis in the spleen
d. Neutrophil granules and toxic oxygen products -Correct Answer ✔C Antibodies
against platelet-specific antigens or against red blood cell antigens of the Rh system
coat those cells at low density, resulting in their preferential removal by phagocytosis in
the spleen, rather than by complement-mediated lysis. These blood cells are not
destroyed by complement-mediated cell lysis, phagocytosis by macrophages, neutrophil
granules, or toxic oxygen products
When soluble antigens from infectious agents enter circulation, what is tissue damage a
result of?
a. Complement-mediated cell lysis
b. Phagocytosis by macrophages
c. Phagocytosis in the spleen
d. Neutrophil granules and toxic oxygen products -Correct Answer ✔D. Of the options
available, only the components of neutrophil granules as well as the several toxic
oxygen products produced by these cells, damage the tissue.
