3. What is the term for the upper midportion of the abdomen?

• A. hypochondriac
• B. iliac
• C. hypogastric
• D. epigastric

4. Are the oral, nasal, orbital, and middle ear cavities in the dorsal cavity?

• A. TRUE
• B. FALSE
• C. Not Sure
• D. None of the above

Correct answer: B

Rationale: The correct answer is False. The oral, nasal, orbital, and middle ear cavities are actually part of the ventral cavity, not the dorsal cavity. The dorsal cavity contains the cranial and spinal cavities, while the ventral cavity includes the thoracic, abdominal, and pelvic cavities. Therefore, these structures are located in the ventral cavity, not the dorsal cavity. Choices A, C, and D are incorrect because these structures are not situated in the dorsal cavity.

5. Calcium concentration in the blood is controlled by which of the following glands?

• A. Hypothalamus gland
• B. Thyroid gland
• C. Pituitary gland

Correct answer: D

Rationale: The correct answer is Parathyroid glands. The parathyroid glands are responsible for regulating calcium levels in the blood by secreting parathyroid hormone (PTH). PTH helps increase calcium levels in the blood when they are too low. The other glands listed, such as the Hypothalamus, Thyroid, and Pituitary glands, do not directly control calcium concentration in the blood.
