How many vertebrae are present in the thoracic region of the human spine?

The correct answer is: 12

The thoracic region of the human spine consists of 12 vertebrae, which are located between the cervical vertebrae in the neck and the lumbar vertebrae in the lower back. These thoracic vertebrae are numbered T1 to T12 and play a critical role in supporting the ribcage, protecting vital organs, and providing attachment points for muscles that facilitate movement and posture. The specific structure and number of thoracic vertebrae are consistent across humans, which is why the answer reflects a standard anatomical understanding. This knowledge is essential for medical assistants, as they often need to comprehend basic human anatomy to assist in various medical settings.
