1. The shoulder is _________ to the elbow.

• A. posterior
• B. proximal
• C. distal
• D. medial

Correct answer: B

Rationale: Proximal refers to a position closer to the point of attachment or origin. In this case, the shoulder is closer to the point of attachment to the body compared to the elbow, making it proximal to the elbow. 'Posterior' refers to the back side of the body, 'distal' means farther away from the point of attachment, and 'medial' refers to the middle of the body. These terms do not accurately describe the relationship between the shoulder and the elbow in this context.

2. Which of the following is not a principal organ of the nervous system?

• A. Brain
• B. Thymus
• C. Ganglia
• D. Spinal cord

Correct answer: B

Rationale: The correct answer is B. The thymus is not a principal organ of the nervous system; it is part of the immune system. The brain, spinal cord, and ganglia are principal organs of the nervous system. The brain is responsible for processing information, the spinal cord helps transmit signals between the brain and the rest of the body, and ganglia are clusters of nerve cells that support the nervous system's functions. Therefore, the thymus is the correct answer as it is not directly involved in nervous system functions.

3. The coronal plane of the body may also be called the ___________ plane.

• A. sagittal
• B. median
• C. frontal
• D. axial

Correct answer: C

Rationale: The correct answer is C: frontal. The coronal plane of the body is also known as the frontal plane. This plane divides the body into front (anterior) and back (posterior) sections. It is perpendicular to the sagittal plane and divides the body into front and back portions. The term 'coronal' is often used in radiology and anatomy to describe this specific anatomical plane. Choices A, B, and D are incorrect because the sagittal plane divides the body into left and right portions, the median plane is another name for the sagittal plane, and the axial plane is a term less commonly used to describe an anatomical plane.

4. What is the most visible part of the ear?

• A. Ear canal
• B. Cochlea
• C. Organ of Corti
• D. Pinna

Correct answer: D

Rationale: The pinna, also known as the auricle, is the most visible part of the ear. Its external shape and location make it easily noticeable on the side of the head. The pinna helps in capturing sound waves and directing them into the ear canal, where the sound transmission process begins. The other structures listed, the Organ of Corti, Cochlea, and Ear canal, are essential parts of the ear involved in hearing and sound processing, but they are not as visibly prominent as the pinna. Therefore, the correct answer is the pinna because of its external visibility and role in capturing sound waves.

5. 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.
