Which muscle of the quadriceps group is located on the side surface of the lower extremity?
- A. Vastus lateralis
- B. Gastrocnemius
- C. Anterior tibialis
- D. Rectus femoris
Correct Answer: A
Rationale: The correct answer is A, Vastus lateralis. The vastus lateralis is a muscle in the quadriceps group located on the lateral side of the thigh and lower extremity. This muscle is essential for knee extension and overall lower limb strength, particularly in activities like walking, running, and jumping.

A tissue examined under the microscope exhibits the following characteristics: cells found on the internal surface of the stomach, no extracellular matrix, cells are tall and thin, and no blood vessels are present in the tissue. What type of tissue is this?
- A. Epithelial
- B. Connective
- C. Muscle
- D. Cartilage
Correct Answer: A
Rationale: The correct answer is A: Epithelial. Epithelial tissue is characterized by tightly packed cells that line the surfaces and cavities of organs. The description provided matches the characteristics of epithelial tissue, such as being found on internal surfaces like the stomach lining, having tall and thin cells, lacking an extracellular matrix, and not containing blood vessels. Connective tissue, muscle tissue, and cartilage do not match the described characteristics.
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 correct answer is B, 'epidermis.' The epidermis is the outermost layer of the skin, providing a protective barrier against environmental factors and regulating water loss. The dermis is located beneath the epidermis and contains important structures like blood vessels and glands. Subcutaneous tissue, also known as the hypodermis, is located below the dermis and serves functions such as insulation and energy storage.
Which structure is located on the sternum?
- A. Xiphoid process
- B. Sesamoid bone
- C. Hyoid bone
- D. Ossified process
Correct Answer: A
Rationale: The xiphoid process is the structure located at the bottom of the sternum. It is a small cartilaginous process that ossifies with age. The sesamoid bone is a small bone embedded within a tendon, not typically found on the sternum. The hyoid bone is a U-shaped bone located in the neck, not on the sternum. 'Ossified' refers to a structure that has become hardened like bone, but it is not a specific structure located on the sternum.
Which structure is part of both the male reproductive system and urinary system?
- A. Epididymis
- B. Ureter
- C. Testis
- D. Urethra
Correct Answer: D
Rationale: The correct answer is D, Urethra. The urethra is a structure shared by both the male reproductive and urinary systems. It serves as a passage for urine to exit the body and for semen during ejaculation. The Epididymis, Testis, and Ureter are not structures that are part of both systems. The Epididymis is involved in sperm maturation, the Testis is responsible for sperm production, and the Ureter transports urine from the kidneys to the bladder.
Which of the following are functions of the skeletal system? (Select the ONE that does not apply.)
- A. Supporting the body
- B. Hemopoiesis
- C. Conducting impulses
- D. Providing protection
Correct Answer: C
Rationale: The correct answer is C, 'Conducting impulses.' The skeletal system's primary functions include supporting the body to maintain posture and provide structure, facilitating movement, protecting internal organs, and producing blood cells through hemopoiesis. Conducting impulses is a function of the nervous system, not the skeletal system.
