Endocrine System MCQ Questions Questions
Question 1 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.

Correct Answer: D

Question 3 of 5
When a hormone acts on a neighbouring cell, it is said to be a?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
The production and release of hormones caused by a chemical such as calcium is a mechanism.
Correct Answer: A
Rationale: Humoral mechanisms trigger hormone release via blood chemicals (e.g., high Ca²⺠stimulates calcitonin) substance-driven. Neural uses nerve signals (e.g., epinephrine). Sensory isn't endocrine external stimuli perception. Hormonal involves hormone-hormone control (e.g., TSH). Humoral response to calcium distinguishes it, key to ion-based regulation, unlike neural, sensory, or hormonal triggers.
Question 5 of 5
Alcohol suppresses the secretion of and thus the reabsorption of water from the kidneys.
Correct Answer: A
Rationale: Alcohol suppresses ADH secretion, reducing kidney water reabsorption diuresis ensues, dehydrating. ADH increase would retain water, opposite effect. Aldosterone reabsorbs sodium, not directly water alcohol's ADH link is primary. ADH suppression with decreased reabsorption distinguishes it, key to alcohol's diuretic effect, unlike increased or aldosterone-based options.
