Endocrine System Questions Questions
Question 1 of 5
Which of the choices below is a type of hormone that acts on neighboring cells without entering the bloodstream?
Correct Answer: D
Rationale: Local hormones and paracrine hormones act on nearby cells without bloodstream travel e.g., prostaglandins (local) or growth factors (paracrine). Autocrine hormones target the secreting cell, circulating hormones travel via blood (e.g., insulin). 'Both 1 and 2' (local and paracrine) fits, as both share this localized action. This distinguishes short-range endocrine signaling, key to tissue-specific responses like inflammation, contrasting with systemic hormone effects.
Question 2 of 5
Which blood glucose-lowering hormone is produced by the pancreatic islet cells?
Correct Answer: A
Rationale: Insulin from pancreatic beta cells lowers blood glucose by promoting uptake and storage, unlike glucagon (raises glucose), somatostatin (inhibits), or thyroid/calcitonin (metabolism/calcium). This distinguishes insulin's hypoglycemic action, key to diabetes management, contrasting with opposing or unrelated hormones.
