Final answer:
The raised part located lateral to the neck of a rib that articulates with the transverse process of a vertebra is called the tubercle. This allows for the attachment of a ligament. The answer is a) Tubercle, transverse process.
Step-by-step explanation:
Lateral to the neck of a rib is an elevated tubercle that articulates with the transverse process of a vertebra and allows for attachment of a ligament. The correct answer to the question is: a) Tubercle, transverse process.
Thoracic vertebrae are structured to have several additional articulation sites, each known as a facet, where a rib is attached. Each thoracic vertebra typically features two facets on the lateral sides of the vertebral body, known as costal facets (costal = "rib"), which articulate with the head of a rib. Additionally, there is a facet located on the transverse process for articulation with the rib's tubercle, a small bump on the posterior side of a rib. This intricate connection allows for the dynamic movement of the ribcage during respiration.
