Verified step by step guidance1
Understand the problem: Marcio broke his T2 and T3 vertebrae. We need to determine the location of these vertebrae in the spine.
Review the anatomy of the spine: The human spine is divided into several regions - cervical, thoracic, lumbar, sacral, and coccygeal.
Identify the thoracic region: The thoracic spine consists of 12 vertebrae, labeled T1 through T12. These vertebrae are located in the upper and middle back.
Locate T2 and T3: T2 and T3 are the second and third vertebrae in the thoracic region, which is situated in the upper back.
Conclude the location: Since T2 and T3 are part of the thoracic spine, Marcio's injury is in his upper back.
