Which spine areas allow for rotation?

The thoracic and cervical spine regions are significant for rotation due to their anatomical structure and the presence of specific joints that allow rotational movement.

In the cervical spine, the first two vertebrae, the atlas (C1) and axis (C2), provide a pivot point for the head and allow for a significant range of motion, including rotation. The ability to turn your head side-to-side is primarily facilitated by these cervical vertebrae.

The thoracic spine, which makes up the middle portion of the back, facilitates rotation more than the lumbar region due to the rib attachments. The ribs connect to the thoracic vertebrae, allowing for both flexibility and stability, which enables the thoracic spine to rotate while maintaining protection for the heart and lungs.

The lumbar spine, while primarily designed for flexion and extension, does have some rotational ability, but this is limited compared to the cervical and thoracic regions. Thus, it can contribute to rotation, but it is not as pronounced as in the other two sections.

In contrast, the sacrum and coccyx are fused structures that do not allow for significant rotation. Therefore, the option correctly emphasizing the cervical and thoracic regions, along with the mention of the lumbar's minimal involvement
