Multiple Choice Questions and Answers
Expert-Verified Explanations
,1. What are the primary cells involved in the adap ve immune response?
A. Eosinophils
B. Neutrophils
C. Lymphocytes
D. Macrophages
Correct Answer: C. Lymphocytes
Verified Explana on:
Lymphocytes, which include B cells, T cells, and natural killer cells, are central to
the adap ve immune response. B lymphocytes mediate humoral immunity
through the produc on of an bodies, while T lymphocytes mediate cellular
immunity by directly a$acking infected or altered cells and orchestra ng immune
responses.

2. T lymphocytes produce what type of immunity?
A. Humoral
B. Innate
C. Cell-mediated
D. Passive
Correct Answer: C. Cell-mediated
, Verified Explana on:
T lymphocytes are the principal effectors of cell-mediated immunity—a branch of
the adap ve immune response. Through various subsets (e.g., CD4+ helper T cells
and CD8+ cytotoxic T cells), they directly a$ack infected, malignant, or foreign
cells and modulate the func ons of other immune cells, rather than producing
an bodies.
3. Explain the challenges of diagnosing autoimmune disorders.
There are over 80 iden fied, many with overlapping presenta ons. Many
manifesta ons are nonspecific and are seen in other non-autoimmune diseases.
Blood tes ng isn't perfect either, as some tests are more generic and can be
elevated in the presence of other diseases.
Verified Explana on:
The diagnosis of autoimmune disorders presents significant challenges due to
both the diversity and non-specificity of clinical presenta ons. With more than 80
known autoimmune condi ons, many share similar signs and symptoms—such as
fa gue, joint pain, or rashes—that can also occur in a wide range of non-
autoimmune diseases, thus making differen al diagnosis difficult. Furthermore,
laboratory assessments, including autoan body panels (e.g., ANA, RF, an -
dsDNA), may yield posi ve results in individuals without any clinical disease or
may be nonspecifically elevated in infec ous or inflammatory condi ons.
Therefore, clinicians must interpret laboratory results in conjunc on with
