Exam Structure
The A&P 2 Midterm Practice Test for the 2026/2027 academic cycle is a comprehensive, 65-question
assessment featuring multiple-choice questions designed to evaluate mastery of systemic anatomy,
physiological mechanisms, and homeostatic regulation.
Introduction
This Anatomy & Physiology II Midterm Practice Test for the 2026/2027 academic year provides model
solutions and detailed rationales for each question. It challenges students to integrate knowledge of
structure and function across multiple organ systems, trace physiological processes step-by-step, and
apply foundational concepts to clinical scenarios and homeostatic imbalances.
Answer Format
All correct anatomical identifications, physiological pathways, and homeostatic mechanisms are
presented in bold green, followed by model solutions in black italic font that explain the
structure-function relationship, sequential physiological events, and clinical significance of each concept
with clear, step-by-step reasoning.
SECTION 1: ENDOCRINE SYSTEM (10 MCQs)
Question 1
Which hormone is responsible for regulating blood calcium levels?
1. Insulin.
2. Parathyroid hormone (PTH).
3. Thyroxine (T4).
4. Cortisol.
Correct Answer: B) Parathyroid hormone (PTH).
,PTH is secreted by the parathyroid glands in response to low blood calcium levels. It increases calcium
reabsorption in the kidneys, stimulates bone resorption to release calcium, and enhances intestinal
absorption of calcium.
Question 2
Which gland is known as the "master gland" of the endocrine system?
1. Thyroid gland.
2. Adrenal gland.
3. Pituitary gland.
4. Pancreas.
Correct Answer: C) Pituitary gland.
The pituitary gland regulates multiple physiological processes by secreting hormones that control other
endocrine glands, such as the thyroid, adrenal cortex, and gonads.
Question 3
Which hormone is responsible for stimulating the production of red blood cells?
1. Erythropoietin (EPO).
2. Thyroid-stimulating hormone (TSH).
3. Follicle-stimulating hormone (FSH).
4. Adrenocorticotropic hormone (ACTH).
Correct Answer: A) Erythropoietin (EPO).
EPO is produced by the kidneys in response to low oxygen levels in the blood. It stimulates the bone
marrow to produce more red blood cells.
Question 4
Which of the following hormones is produced by the adrenal medulla?
1. Cortisol.
2. Aldosterone.
3. Epinephrine.
, 4. Thyroxine.
Correct Answer: C) Epinephrine.
The adrenal medulla produces catecholamines, including epinephrine (adrenaline) and norepinephrine,
which are involved in the "fight or flight" response.
Question 5
Which hormone is responsible for lowering blood glucose levels?
1. Glucagon.
2. Insulin.
3. Cortisol.
4. Epinephrine.
Correct Answer: B) Insulin.
Insulin is secreted by the pancreas in response to high blood glucose levels. It promotes the uptake of
glucose by cells and the storage of glucose as glycogen in the liver and muscles.
Question 6
Which of the following is a symptom of hyperthyroidism?
1. Weight gain.
2. Fatigue.
3. Heat intolerance.
4. Dry skin.
Correct Answer: C) Heat intolerance.
Hyperthyroidism, caused by excessive thyroid hormone production, increases metabolic rate, leading to
symptoms such as heat intolerance, weight loss, and nervousness.
Question 7
Which gland produces melatonin?
