The vertebral column, also known as the spine or spinal column, is a series of bones that extends from the base of the skull to the pelvis. It serves multiple functions in the human body.
1. Support and structure:
- The vertebral column provides support and structure to the body, allowing us to maintain an upright posture.
- It forms the main framework of the trunk, providing stability and balance.
- The column is composed of individual vertebrae, which are stacked on top of each other, forming a flexible and strong structure.
2. Protection of the spinal cord:
- One of the primary functions of the vertebral column is to protect the spinal cord, which is a vital part of the central nervous system.
- The vertebrae enclose and safeguard the delicate spinal cord, preventing injury from external forces.
3. Attachment point for ribs and muscles:
- The vertebral column serves as an attachment point for various muscles of the back and ribs.
- Muscles of the back, such as the erector spinae, attach to the vertebrae and play a crucial role in maintaining posture and movement.
- The ribs articulate with the thoracic vertebrae, forming the rib cage and protecting vital organs, such as the heart and lungs.
4. Articulation of upper and lower limbs with the axial skeleton:
- This statement is incorrect as the vertebral column is not directly involved in the articulation of the upper and lower limbs with the axial skeleton.
- The upper limbs articulate with the axial skeleton through the pectoral girdle (clavicle and scapula) and the lower limbs articulate with the axial skeleton through the pelvic girdle (hip bones).
- However, the vertebral column does play a role in providing support and stability for these limb articulations.
In conclusion, the correct answer is option A. The vertebral column does not directly help in the articulation of the upper and lower limbs with the axial skeleton.

This is the correct option as this is not a function of the vertebral column. Pectoral and pelvic girdle bones help in the articulation of the upper and the lower limbs, respectively, with the axial skeleton.
