Which region of the spine provides attachment points for the ribs?
A
Lumbar region
B
Cervical region
C
Thoracic region
D
Sacral region
Verified step by step guidance1
Begin by identifying the main regions of the spine: cervical, thoracic, lumbar, sacral, and coccygeal.
Understand the function of each region: the cervical region supports the head, the thoracic region provides attachment points for the ribs, the lumbar region supports the lower back, the sacral region connects the spine to the pelvis, and the coccygeal region forms the tailbone.
Focus on the thoracic region, which is composed of 12 vertebrae (T1-T12). These vertebrae have facets that articulate with the ribs, providing structural support and protection for the thoracic cavity.
Recognize that the ribs are attached to the thoracic vertebrae via costal facets, which are specialized structures on the vertebrae that allow for rib articulation.
Conclude that the thoracic region is the correct answer, as it is the only region of the spine that provides attachment points for the ribs.
