Before birth, these vertebrae grow together (or fuse) creating one large РІР‚СљspecializedРІР‚Сњ bone that forms the base of your spine and center of your pelvis. The sacrum is actually a group of specialized vertebrae that connects the spine to the pelvis. Having six vertebrae does not seem to cause a problem.Р”В«elow the lumbar spine is the sacrum (sack-rum). It is usually made up of five vertebrae, however, some people may have six lumbar vertebrae. The lumbar spine is the lower portion of the spine. The thoracic spine is the center part of the spine. The cervical spine is the upper part of the spine known as the neck.

The spine itself has three main segments: the cervical (ser-vi-cal) spine, the thoracic (thor-a-sic) spine, and the lumbar (lum-bar) spine. Spine detail: cervical spine, thoracic spine, lumber spine, sacrum. These roots exit the spine on both sides through spaces called neural foramina (noor-al for-a-min-ah) between each vertebra. The spine branches off into thirty-one pairs of nerve roots. The spinal cord itself is a large bundle of millions of nerves that carries messages from your brain to the rest of your body, and from every part of your body back to your brain. The spinal cord runs through this long hollow tube. When the vertebrae stack on top of each other, the holes line up to form a long hollow tube that runs the length of the spine. Facet joints link the vertebrae together and give them the flexibility to move against each other. Spinal column joints are called facet (fuh-set) joints. Like other parts of the body such as the knee or elbow, the spinal column also has joints.

There are also tendons in the spine, which connect muscles to the vertebrae. Each vertebra is held to the others by groups of ligaments. The disc helps absorb pressure and keeps the bones from rubbing against each other. The laminae includes the spinous (spine-us) process, which is the bone you feel when you run your hand down someoneРІР‚в„ўs back, two transverse (trans-verse) processes where the back muscles connect to the vertebrae, and the pedicle (ped-i-cuhl) that connects the two sides of the lamina.Р”В«etween each vertebra is a soft, gel-like cushion called a disc. Each vertebra is made up of a large bone called the body, and laminae (lam-in-ay) which extend from the body and form a ring to enclose and protect the spinal cord.

The vertebrae protect and support the spinal cord, and bear most of the weightput on you spine. Together, all the bones that make up the spine are called vertebrae (vert-a-bray). These are the building blocks of the spinal column. Each bone is called a vertebra (ver-ta-bruh). That is why keeping your spine healthy is vital if you want to live an active life. Without a spinal cord, you could not move any part of your body, and your organs could not function. The spinal cord is the column of nerves that connects your brain with the rest of your body, allowing you to control your movements. The spine also protects your spinal cord. Your spine gives your body structure and support. Without it, you could not keep yourself upright or even stand up.

The spine is one of the most important parts of your body.
