Which of the following structures lies between adjacent vertebral bodies and connects them?

The intervertebral discs are integral structures located between adjacent vertebral bodies in the spine. Their primary function is to act as shock absorbers, providing cushioning for the vertebrae during movement and impact. Each disc is composed of a tough outer layer called the annulus fibrosus and a softer inner layer known as the nucleus pulposus. This unique design allows the discs to withstand compressive forces while also permitting a degree of flexibility and movement between the vertebrae, helping to maintain spinal alignment and overall mobility.

Understanding the role of intervertebral discs is crucial in the context of spinal health and function, as issues with these discs, such as herniation or degeneration, can lead to pain and compromised mobility. This highlights the discs' importance in connecting and supporting adjacent vertebral bodies within the spine's biomechanical structure.
