SECTION 1: ENDOCRINE SYSTEM (30 QUESTIONS)
1. Which of the following is the primary function of the endocrine system?
A) To produce rapid, short-lived responses through electrical signals
B) To secrete hormones directly into the bloodstream for transport to target cells
C) To secrete substances through ducts onto epithelial surfaces
D) To provide structural support for body organs
Rationale: The endocrine system uses ductless glands that secrete hormones directly into the
bloodstream, producing slower but longer-lasting effects than the nervous system.
2. Which of the following is a key difference between endocrine and exocrine glands?
A) Endocrine glands have ducts; exocrine glands do not
B) Exocrine glands secrete hormones; endocrine glands secrete enzymes
C) Endocrine glands are ductless and secrete into the bloodstream; exocrine glands secrete
through ducts
D) Endocrine glands are only found in the brain

,Page 3 of 102
Rationale: Endocrine glands are ductless and release hormones into the bloodstream, while
exocrine glands secrete their products through ducts onto epithelial surfaces.
3. The "master gland" that regulates many other endocrine glands and is itself controlled by the
hypothalamus is the:
A) Thyroid gland
B) Adrenal gland
C) Pituitary gland
D) Pineal gland
Rationale: The pituitary gland is often called the "master gland" because it secretes hormones
that control other endocrine glands, and its activity is regulated by the hypothalamus.
4. Which hormone class is derived from cholesterol and can cross the plasma membrane to bind
to intracellular receptors?
A) Protein hormones
B) Amino acid derivatives
C) Steroid hormones
D) Peptide hormones
Rationale: Steroid hormones are lipid-soluble, derived from cholesterol, and can diffuse through
the plasma membrane to bind to receptors inside the cell.
5. Which of the following is an example of a second messenger system used by water-soluble
hormones?
A) Direct gene activation

, Page 4 of 102
B) Cyclic AMP (cAMP) pathway
C) Steroid receptor binding
D) Thyroid hormone mechanism
Rationale: Water-soluble hormones cannot cross the plasma membrane; they bind to
membrane receptors and use second messengers like cAMP to exert their effects.
6. The hypothalamus communicates with the posterior pituitary via the:
A) Hypophyseal portal system
B) Nervous system (neuronal connections)
C) Systemic circulation
D) Lymphatic system
Rationale: The posterior pituitary is connected to the hypothalamus by neurons; hypothalamic
neurons synthesize oxytocin and ADH, which are stored and released from the posterior
pituitary.
7. Which hormone is released by the posterior pituitary and acts on the kidneys to conserve
water?
A) Oxytocin
B) Antidiuretic hormone (ADH)
C) Growth hormone
D) Prolactin
Rationale: ADH (vasopressin) is released from the posterior pituitary and promotes water
reabsorption in the kidneys.
