The sacral spine consists of five segments, S1 - S5, that together affect nerve communication to the lower portion of the body. , the snake can open its mouth wider) and greater jaw flexibility. It is shaped like an upside-down triangle and sits at the bottom of the spinal column, connecting it to the pelvis. A fracture is a break to any part of the vertebrae. Compression fractures of the spine generally occur from too much pressure on the vertebral body. It can occur in any of the structures that make up your back, including the discs, bones, joints, ligaments, muscles, nerves and more. The axis, also known as the epistropheus, is the second cervical vertebra (C2) that has some similarities to a typical cervical vertebra but is categorized as an atypical vertebra because of its unique features. The twelve thoracic vertebrae are strong bones that are located in the middle of the vertebral column, sandwhiched between the cervical ones above and the lumbar vertebrae below. Cervical disk replacement surgery involves removing a diseased cervical disk and replacing it with an artificial disk. The vertebral bodies stack on top of each other and handle most of the spine’s stresses and loads while being cushioned by the intervertebral discs in between. Your spine is made up of vertebrae (bones), disks, joints, soft tissues, nerves and your spinal cord. The sacral region (sacrum) is at the bottom of the spine and lies between the fifth segment of the lumbar spine (L5) and the coccyx (tailbone). Vertebra L5 is the most common site of spondylolysis and spondylolisthesis. Bed rest may be needed for a mild fracture.

Spinal fusion is surgery to connect two or more bones in any part of the spine. Our revolutionary healthcare model goes beyond traditional pharmacy benefit management to help build efficiencies,. This creates the lumbosacral angle between the lumbar region of the vertebrae and the sacrum. Conversely, the joint between the C1 and C2 vertebrae allows the head to turn left and right. The spinal cord in this region has protection from five durable and mobile vertebrae (L1-L5) that allow for the dispersion of axial forces. There are also tendons that fasten muscles to the vertebrae. Pig skeleton anatomy. The bony ring that is attached to the back of the vertebral body remains largely unphased.
