Answer :
Final answer:
Cartilage is the primary structure providing support and flexibility to the spine, found in intervertebral discs that allow for bending and cushioning of the spinal column. The correct option is C.
Explanation:
The structure primarily responsible for providing support and flexibility to the spine is cartilage. Cartilage is a type of dense connective tissue that is strong, yet flexible, and is found between bones at joints, providing a smooth surface for these bones to move over. In the spine, cartilage exists as intervertebral discs which provide cushioning and allow for the flexibility and bending of the spinal column. Ligaments also play a crucial role in maintaining spinal integrity by holding bones together and restricting excessive movement that could lead to injury.
The structure primarily responsible for providing support and flexibility to the spine is cartilage. Cartilage is a type of dense connective tissue that covers the ends of bones at joints, providing a smooth surface for bones to move over. It is strong but flexible and contributes to the overall strength and structure of the spine.
