Is the statement 'Each of the 12 ribs articulates with one vertebra' true or false?

• A. False
• B. True

Answer: (A)

Verified step by step guidance

1. Understand the anatomy of the ribs and their articulation with the vertebrae. The human rib cage consists of 12 pairs of ribs, and each rib articulates with the thoracic vertebrae.
2. Learn about the thoracic vertebrae. There are 12 thoracic vertebrae, and each rib typically articulates with two vertebrae: the vertebra of the same number and the one above it. For example, rib 5 articulates with thoracic vertebrae T4 and T5.
3. Examine the rib articulation points. The ribs articulate with the vertebrae at two locations: the costovertebral joint (head of the rib with the vertebral body) and the costotransverse joint (tubercle of the rib with the transverse process).
4. Clarify the statement in the problem. The statement 'Each of the 12 ribs articulates with one vertebra' is false because each rib typically articulates with two vertebrae, not just one.
5. Conclude the reasoning. The correct answer is 'False' because the anatomy of the rib cage and thoracic vertebrae demonstrates that ribs articulate with more than one vertebra.
