Answer Key
1. Differentiate between hypertrophy and hyperplasia, providing
an example for each. Hypertrophy is an increase in the size of
individual cells, which leads to an enlarged tissue mass; an example is
, the increase in muscle size from exercise. Hyperplasia is an increase in
the number of cells, which also results in an enlarged tissue mass; an
example is the thickening of the endometrium during the menstrual
cycle.
2. What is a double-blind study in health research, and what is its
primary purpose? A double-blind study is a research method in which
neither the participants nor the researchers know who is receiving the
actual treatment versus a placebo. This design is used to prevent bias
in research results, both from the participants' expectations and the
researchers' observations.
3. Explain the primary mechanism of radiation therapy and
identify the types of cells it targets most effectively. Radiation
therapy works by destroying cells. It is most effective against primary,
rapidly dividing cells, which is a characteristic of many cancerous
tumors.
4. Define the condition known as cachexia. Cachexia is a state of
severe tissue wasting. It is a complex metabolic syndrome associated
with underlying illness and characterized by the loss of muscle with or
without loss of fat mass.
5. What is neutropenia, and why is it a significant risk for
patients undergoing chemotherapy? Neutropenia is a condition
characterized by a low level of neutrophils, a type of white blood cell.
Its development during chemotherapy is a serious concern because it
indicates that the patient is at a high risk for infection due to a
compromised immune system.
6. Describe the cellular change known as metaplasia and provide
a specific example. Metaplasia is a process where one mature cell
type is replaced by another mature cell type, often as an adaptive
mechanism to prolonged irritation. An example is the replacement of
ciliated columnar epithelium with squamous epithelium in the airways
of smokers.
7. What is the key difference between apoptosis and necrosis as
forms of cell death? Apoptosis refers to programmed cell death,
which is a normal, active, and organized process in the body. In
contrast, necrosis is the passive death of a cell due to irreversible
damage or injury, which causes cellular disintegration (lysis) and
results in inflammation in the surrounding tissue.
8. Explain the inheritance pattern of autosomal dominant
disorders and identify whether carriers are possible. In
autosomal dominant disorders, the inheritance of just one affected
