Endocrine System MCQ Questions Questions
Question 1 of 5
What controls hormone release from the anterior pituitary gland?
Correct Answer: C
Rationale: The anterior pituitary is regulated by hypothalamic releasing hormones (e.g., TRH, GHRH) via the hypophyseal portal system, not muscle, peripheral nerves, thalamus, or CSF directly. This hypothalamic control distinguishes it as the endocrine 'master gland' coordinator, critical for thyroid, adrenal, and growth functions, contrasting with unrelated physiological triggers.
Question 2 of 5
Which of the following hormones play key regulatory roles in the body's long-term response to stress?
Correct Answer: C
Rationale: Cortisol (glucocorticoid), hGH (growth), and thyroid hormones sustain long-term stress responses energy mobilization, repair, metabolism unlike insulin/glucagon (short-term glucose), aldosterone (electrolytes), PTH/calcitonin (calcium). This triad distinguishes chronic stress adaptation, vital for survival, contrasting with acute or unrelated regulators.
Question 3 of 5
Which of the following is an incorrect pairing of a body system and an endocrine contribution to that system?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
Which of the following diseases result when the cells marked in the histology image are destroyed by the immune system?
Correct Answer: D
Rationale: Pancreatic beta cell destruction (likely marked) causes type 1 diabetes (insulin loss), not Cushing's (pituitary), Addison's (adrenal), acromegaly (GH), or diabetes insipidus (ADH). This distinguishes autoimmune diabetes, critical for glucose control, contrasting with adrenal or pituitary disorders.

All prostaglandins are derived from a 20-carbon precursor molecule called
Correct Answer: D
