The correct answer is option C: Spinal cord.
The vertebral column, also known as the spine or backbone, is a series of bones called vertebrae that run down the middle of the back. It is a crucial part of the skeletal system and plays a vital role in protecting the spinal cord.
- The Spinal Cord:
The spinal cord is a long, thin, tubular bundle of nerves that extends from the base of the brain down to the lower back. It is a vital part of the central nervous system and functions as a communication pathway between the brain and the rest of the body. The spinal cord carries sensory information from the body to the brain and transmits motor signals from the brain to the body, allowing us to move and perceive sensations.
- Protection by the Vertebral Column:
The vertebral column acts as a protective structure for the delicate spinal cord. It surrounds and encloses the spinal cord, providing it with support and shielding it from potential injury. The vertebrae are stacked on top of each other, forming a strong and flexible column that can withstand various movements and impacts.
- Structure of the Vertebral Column:
The vertebral column is made up of 33 individual bones called vertebrae. These vertebrae are divided into five regions: cervical (neck), thoracic (upper back), lumbar (lower back), sacrum, and coccyx (tailbone). Each vertebra has a unique structure, but they all share some common features such as a round vertebral body, a vertebral arch, and bony processes.
- Intervertebral Discs:
In addition to the vertebrae, the vertebral column also includes intervertebral discs. These discs are located between adjacent vertebrae and act as shock absorbers, cushioning the spine and reducing the impact of movements. They also provide flexibility and allow for bending, twisting, and other movements of the spine.
In conclusion, the bones in the vertebral column protect the spinal cord. The spinal cord is a crucial part of the central nervous system, and the vertebral column acts as a protective structure, surrounding and supporting it.
