Question 1
The study of the structure and function of the human body is the
foundation of which scientific discipline?
A. Pathophysiology
B. Anatomy and Physiology
C. Histology
D. Embryology
Rationale: Anatomy is the study of the structure of the body, while
physiology is the study of the function of the body. Together, they form
the foundation of understanding how the human body works.
Pathophysiology studies disease processes, histology studies tissues,
and embryology studies development.
Question 2
Which of the following is a primary function of the endocrine system?
A. To transport nutrients and oxygen to tissues
B. To provide rapid, short-term communication between cells
C. To secrete hormones that regulate long-term processes such as
growth, metabolism, and reproduction
D. To defend the body against pathogens
,2|Page
Rationale: The endocrine system secretes hormones that regulate
long-term processes including growth, metabolism, reproduction, and
homeostasis. The cardiovascular system transports nutrients and
oxygen, the nervous system provides rapid communication, and the
immune system defends against pathogens.
Question 3
Hormones that bind to intracellular receptors are typically:
A. Water-soluble
B. Large protein molecules
C. Hydrophilic
D. Lipid-soluble
Rationale: Lipid-soluble hormones (e.g., steroid hormones, thyroid
hormones) can diffuse across the plasma membrane and bind to
intracellular receptors. Water-soluble hormones (e.g., peptide
hormones) bind to cell surface receptors and act through second
messenger systems.
Question 4
The hypothalamus communicates with the anterior pituitary gland via:
A. The hypothalamic-hypophyseal tract
B. The hypophyseal portal system
C. The infundibulum
D. Direct neural connections
Rationale: The hypophyseal portal system is a network of blood vessels
that transports hypothalamic releasing and inhibiting hormones
directly to the anterior pituitary. The hypothalamic-hypophyseal tract
connects the hypothalamus to the posterior pituitary.
Question 5
Which of the following hormones is synthesized in the hypothalamus
and stored in the posterior pituitary?
,3|Page
A. Growth hormone (GH)
B. Thyroid-stimulating hormone (TSH)
C. Adrenocorticotropic hormone (ACTH)
D. Antidiuretic hormone (ADH)
Rationale: ADH (vasopressin) and oxytocin are synthesized in the
hypothalamic nuclei and transported down the hypothalamic-
hypophyseal tract to the posterior pituitary, where they are stored and
released. GH, TSH, and ACTH are synthesized in the anterior
pituitary.
Question 6
A patient with hyperthyroidism would most likely exhibit which of the
following clinical manifestations?
A. Weight gain and cold intolerance
B. Bradycardia and constipation
C. Weight loss, tachycardia, and heat intolerance
D. Lethargy and dry skin
Rationale: Hyperthyroidism results from excessive thyroid hormone,
increasing the metabolic rate. Clinical manifestations include weight
loss, tachycardia, heat intolerance, diaphoresis, nervousness, and
diarrhea. Weight gain, cold intolerance, bradycardia, and lethargy are
signs of hypothyroidism.
Question 7
A patient with primary hypothyroidism would most likely have which of
the following laboratory findings?
A. Decreased TSH and decreased free T4
B. Decreased TSH and elevated free T4
C. Elevated TSH and decreased free T4
D. Elevated TSH and elevated free T4
, 4|Page
Rationale: In primary hypothyroidism, the thyroid gland fails to
produce adequate thyroid hormone, leading to decreased free T4. The
lack of negative feedback on the pituitary results in elevated TSH. This
pattern (elevated TSH, low free T4) is diagnostic of primary
hypothyroidism.
Question 8
The most common cause of Cushing's syndrome is:
A. Adrenal adenoma
B. Ectopic ACTH production
C. Pituitary adenoma (Cushing's disease)
D. Iatrogenic (glucocorticoid therapy)
Rationale: Cushing's syndrome is caused by chronic exposure to
excess cortisol. The most common cause is iatrogenic (exogenous
glucocorticoid therapy). Among endogenous causes, pituitary
adenoma (Cushing's disease) is the most common, followed by adrenal
adenoma and ectopic ACTH syndrome.
Question 9
A patient with Addison's disease (primary adrenal insufficiency) would
most likely have which of the following?
A. Hypertension and hyperglycemia
B. Weight gain and moon facies
C. Hypotension, hyperpigmentation, and hyponatremia
D. Tachycardia and heat intolerance
Rationale: Addison's disease results from destruction of the adrenal
cortex, leading to deficiency of cortisol and aldosterone. Clinical
features include hypotension, hyperpigmentation (due to increased
ACTH and MSH), hyponatremia, hyperkalemia, fatigue, and weight
loss.
