1. Where will a person who has damage to their ulnar nerve experience decreased sensation?

• A. Leg
• B. Arm
• C. Face
• D. Abdomen

Correct answer: B

Rationale: The ulnar nerve innervates the forearm and hand, specifically providing sensation to the ring and little fingers. Damage to this nerve can lead to decreased sensation in these areas, making the arm the correct answer. Choices A, C, and D are incorrect because the ulnar nerve does not supply sensation to the leg, face, or abdomen.

2. To which two systems does the urethra belong?

• A. Reproductive and endocrine
• B. Urinary and reproductive
• C. Endocrine and urinary
• D. Digestive and cardiovascular

Correct answer: B

Rationale: The urethra belongs to both the urinary and reproductive systems. In the urinary system, it functions as a passage for urine from the bladder to exit the body. In the reproductive system, it serves as a conduit for the expulsion of semen during ejaculation. Choice A is incorrect because the urethra is not part of the endocrine system. Choice C is also incorrect because the urethra is not primarily associated with the endocrine system. Choice D is incorrect as the urethra is not part of the digestive or cardiovascular systems.

3. What is a common finding in a whiplash injury?

• A. Cardiopulmonary issues
• B. Side-to-side spinal curvature
• C. Eventual herniation of discs
• D. Traumatic injury to ligaments

Correct answer: D

Rationale: A common finding in a whiplash injury is a traumatic injury to ligaments. Whiplash occurs due to sudden hyperextension and hyperflexion of the neck, leading to strain or tearing of ligaments in the neck. This can manifest as neck pain, stiffness, and limited range of motion. While other complications like cardiopulmonary problems, side-to-side spinal curvature, or eventual herniation of discs are not typically associated with whiplash injuries.

4. How does a sagittal section divide the body?

• A. Into right and left regions
• B. Into upper and lower regions
• C. Into front and back regions
• D. Between the dorsal and ventral cavities

Correct answer: A

Rationale: A sagittal section divides the body into right and left regions. This type of section runs longitudinally from front to back, separating the body into right and left halves. Sagittal sections are crucial for understanding the anatomical structure and orientation of various body parts. Choices B, C, and D are incorrect because a sagittal section specifically divides the body into right and left portions, not upper and lower regions, front and back regions, or between the dorsal and ventral cavities.

5. What is the function of the coronary artery?

• A. It carries oxygenated blood to the heart muscle.
• B. It carries deoxygenated blood to the lungs.
• C. It distributes blood to the body.
• D. It supplies blood to the heart muscle.

Correct answer: D

Rationale: The correct answer is D: 'It supplies blood to the heart muscle.' The coronary artery's main function is to supply oxygenated blood to the heart muscle, ensuring that the heart receives the necessary nutrients and oxygen it needs to function properly. Choices A, B, and C are incorrect because the coronary artery specifically delivers oxygenated blood to the heart muscle, not deoxygenated blood to the lungs or blood to the rest of the body.
