Answers)
Section A: Multiple-Choice Questions (70 Marks)
Each question is worth 1 mark. Choose the most correct answer.
Topic 1: Fundamental Principles of Endocrinology
1. Which of the following statements most accurately describes the primary function of the
endocrine system?
A. It utilizes a system of ducts to transport chemical messengers directly to target organs.
B. It produces hormones that are secreted into the circulatory system to act on specific target
cells containing appropriate receptors.
C. It provides a rapid, short-lived response to stimuli through the use of neurotransmitters across
synaptic clefts.
D. It primarily functions to produce structural proteins for growth and maintenance of tissues.
Answer: B
Explanation: The endocrine system is a ductless system that relies on the circulatory system to
transport hormones, which then act on cells possessing specific receptors. Option A describes an
exocrine function, while C describes the nervous system.
2. The mechanism by which most endocrine glands regulate hormone secretion, akin to a
thermostat maintaining a set temperature, is known as:
A. Positive feedback
B. Neural stimulation
C. Negative feedback
D. Hormonal antagonism
Answer: C
Explanation: Negative feedback is the primary regulatory mechanism where a rising level of a
hormone or its effect inhibits further secretion of that hormone, maintaining homeostasis.
Positive feedback amplifies a response.
, 3. A cell is considered a "target cell" for a specific hormone if it:
A. Is located in the same gland that produces the hormone.
B. Possesses specific receptor proteins that bind to the hormone.
C. Is exposed to the hormone via the circulatory system.
D. Is capable of producing the same hormone.
Answer: B
Explanation: The "lock and key" model dictates that a hormone can only affect a cell if that cell
has the corresponding receptor ("lock") for the hormone ("key"). Exposure alone (Option C) is
insufficient.
4. The "lock and key" arrangement in hormone action refers to:
A. The shape of the endocrine gland matching the shape of the target organ.
B. The specific binding of a hormone to its receptor on a target cell.
C. The mechanism by which hormones are transported in the bloodstream.
D. The feedback loop between the hypothalamus and pituitary.
Answer: B
Explanation: The "lock and key" model describes the highly specific interaction between a
hormone (key) and its receptor (lock) on a target cell, ensuring that only cells with the correct
receptor respond to a given hormone.
5. Which of the following is NOT a characteristic of the endocrine system?
A. Uses the circulatory system for transport
B. Produces hormones that act on specific target cells
C. Uses ducts to deliver secretions
D. Works with the nervous system to maintain homeostasis
Answer: C
Explanation: The endocrine system is ductless. It secretes hormones directly into the
bloodstream. Exocrine glands use ducts to deliver their secretions.
6. Hormones are best described as:
A. Electrical signals transmitted along neurons.
B. Chemical messengers produced by endocrine glands.
C. Structural proteins that build tissues.
D. Enzymes that catalyze metabolic reactions.
