What are the segments of the spine and their corresponding vertebrae?

The correct answer identifies the segments of the spine accurately as cervical, thoracic, and lumbar, along with their corresponding number of vertebrae: seven cervical vertebrae, twelve thoracic vertebrae, and five lumbar vertebrae.

Understanding the spinal structure is crucial for both anatomy and movement practices such as Pilates. The cervical region, which consists of seven vertebrae (C1-C7), is responsible for supporting the head and facilitating a wide range of motion. The thoracic region, made up of twelve vertebrae (T1-T12), connects to the ribs and is less mobile due to the rib cage’s protective framework surrounding the heart and lungs. Finally, the lumbar region consists of five vertebrae (L1-L5) and supports most of the body's weight, allowing for greater flexibility and movement compared to the thoracic region.

Knowing the correct number of vertebrae in each spinal section provides a solid foundation for understanding how the spine supports various movements and postures, which is essential for anyone studying Pilates and its related anatomical concepts.
