1. Which gland is responsible for regulating metabolism and growth?

• A. Thyroid gland
• B. Pituitary gland
• C. Adrenal gland
• D. Pineal gland

Correct answer: A

Rationale: The correct answer is the Thyroid gland. The thyroid gland is responsible for regulating metabolism and growth. It produces hormones such as thyroxine (T4) and triiodothyronine (T3), which play essential roles in controlling metabolic processes, growth, and development throughout the body. Choice B, the Pituitary gland, although important for hormone regulation, is not primarily responsible for regulating metabolism and growth. Choices C and D, the Adrenal gland and Pineal gland, respectively, have different functions and are not primarily involved in regulating metabolism and growth.

2. Which is a posterior feature of the human leg?

• A. Patella
• B. Quadriceps sartorius
• C. Triceps brachii
• D. Achilles tendon

Correct answer: D

Rationale: The correct answer is the Achilles tendon. The Achilles tendon is a strong tendon located at the back of the human leg, connecting the calf muscles to the heel bone. This positioning makes it a posterior feature, situated at the rear of the leg. The patella, also known as the kneecap, is positioned at the front of the leg, making it an anterior feature. The quadriceps sartorius are muscles located in the front of the thigh, not at the back of the leg. Additionally, the triceps brachii is a muscle found in the upper arm, not in the leg, making it an incorrect choice.

3. Which part of the brain is responsible for controlling balance and coordination?

• A. Cerebellum
• B. Cerebrum
• C. Brainstem
• D. Medulla oblongata

Correct answer: A

Rationale: The cerebellum is the correct answer. It is responsible for controlling balance, coordination, and fine motor movements. The cerebrum is mainly associated with higher brain functions such as thinking and decision-making, not specifically balance and coordination. The brainstem is responsible for basic life functions like breathing and heartbeat, while the medulla oblongata is involved in regulating autonomic functions like breathing, heart rate, and blood pressure. Therefore, the cerebellum stands out as the key brain region for maintaining physical control and movement.

4. How many bones are in the human foot?

• A. 6
• B. 16
• C. 26
• D. 36

Correct answer: C

Rationale: The correct answer is C: 26. The human foot consists of 26 bones, including tarsal bones, metatarsal bones, and phalanges. These bones collaborate to offer support, flexibility, and stability for various activities like standing, walking, and running. Choice A (6) is incorrect as it is too low for the number of bones in the human foot. Choice B (16) is incorrect as it underestimates the actual number of bones in the foot. Choice D (36) is incorrect as it overestimates the number of bones in the human foot.

5. Which gland controls Calciferol?

• A. Thyroid
• B. Pituitary
• C. Parathyroid
• D. Hypothalamus

Correct answer: C

Rationale: Calciferol, commonly known as Vitamin D, is regulated by the parathyroid gland, not the thyroid, pituitary, or hypothalamus. The parathyroid gland plays a crucial role in maintaining calcium and phosphorus balance in the body by regulating the production of calcitriol, the active form of Vitamin D. This hormone helps in the absorption of calcium from the intestines and its reabsorption in the kidneys to maintain proper calcium levels in the blood. Therefore, the correct answer is the Parathyroid gland (Choice C). Choices A, B, and D are incorrect as they do not have a direct role in controlling Calciferol.
