How many bones are typically found in the thoracic spine?

The thoracic spine is composed of 12 vertebrae, which are labeled T1 through T12. These vertebrae are located in the upper and mid-back region and play a crucial role in providing stability and support for the ribcage. They are also integral to the attachment points for the ribs, allowing for the protection of vital organs such as the heart and lungs. Each thoracic vertebra connects with a pair of ribs, contributing to the overall structure and function of the thoracic skeleton.

This anatomical feature distinguishes the thoracic spine from other regions of the spine, such as the cervical spine, which contains 7 vertebrae, and the lumbar spine, which consists of 5 vertebrae.
