Which sections divide the vertebral column?

The vertebral column, also known as the spine, is divided into distinct regions that play specific roles in providing structure, support, and flexibility to the human body. The correct answer identifies the three primary sections of the vertebral column: cervical, thoracic, and lumbar.

The cervical section consists of seven vertebrae (C1-C7) located at the neck, allowing for flexibility and a wide range of motion in the head and neck area. The thoracic region comprises twelve vertebrae (T1-T12) that connect to the ribs and help protect vital organs within the thoracic cavity, such as the heart and lungs. The lumbar section contains five vertebrae (L1-L5) situated in the lower back, which support much of the body’s weight and are crucial for various movements, such as bending and lifting.

The other options do not correspond to the proper division of the vertebral column. The axial and appendicular system refers to broader classifications in human skeletal anatomy, while skull and spine represents more general parts of the body rather than specific divisions of the vertebral column. Longitudinal and transverse are terms used in anatomy to describe different orientations and planes but do not define sections of the vertebral column. Thus
