1. Which of the following are considered normal values for the measure of a person’s pulse and blood pressure?

• A. 55 beats per minute and 75 over 60 mm Hg
• B. 72 beats per minute and 120 over 80 mm Hg
• C. 100 beats per minute and 140 over 100 mm Hg
• D. 160 beats per minute and 100 over 70 mm Hg

Correct answer: B

Rationale: Normal values for pulse rate typically range between 60 to 100 beats per minute, while normal blood pressure values are usually around 120/80 mm Hg. Option B falls within these normal ranges for both pulse rate and blood pressure, making it the correct choice. Choices A, C, and D have either pulse rate, blood pressure, or both values outside the normal ranges, making them incorrect.

2. The anterior chamber of the eye lies between the ___________.

• A. iris and lens
• B. lens and retina
• C. cornea and iris
• D. retina and optic nerve

Correct answer: A

Rationale: The anterior chamber of the eye is the fluid-filled space located between the cornea and the iris in the front part of the eye. It contains aqueous humor and helps maintain intraocular pressure. The space between the iris and the lens is known as the anterior chamber, making option A, 'iris and lens,' the correct choice. Options B, C, and D are incorrect because they do not describe the correct anatomical location of the anterior chamber.

3. 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.

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

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

Correct answer: A

Rationale: The correct answer is the cerebellum. The cerebellum, situated at the back of the brain, is responsible for coordinating voluntary movements and maintaining balance and posture. It receives information from the sensory systems, the spinal cord, and other parts of the brain to regulate motor movements. The cerebrum (choice B) is responsible for higher brain functions such as thinking and decision-making, the medulla oblongata (choice C) controls vital autonomic functions like breathing and heart rate, and the hypothalamus (choice D) is involved in regulating basic biological needs like hunger, thirst, and body temperature.

5. What is the name of the outermost layer of the skin?

• A. dermis
• B. epidermis
• C. subcutaneous tissue
• D. hypodermis

Correct answer: B

Rationale: The epidermis is the correct answer as it is the outermost layer of the skin. It acts as a protective barrier against environmental factors and helps in regulating moisture balance. The epidermis is also where new skin cells are continuously formed and contains melanocytes responsible for skin pigmentation. Choices A, C, and D are incorrect. The dermis is the layer beneath the epidermis, the subcutaneous tissue is the deepest layer of the skin, and the hypodermis lies below the dermis.
