The normal anatomy of the spine is usually described by dividing up the spine into three major sections: the cervical, the thoracic, and the lumbar spine. (Below the lumbar spine is a bone called the sacrum, which is part of the pelvis). Each section is made up of individual bones, called vertebrae.
How many regions are in the spine?
The five regions of the spinal column. The abdominal and back muscles maintain the spine’s natural curves.
How many sections is the spine divided?
The spine is composed of 33 bones, called vertebrae, divided into five sections: the cervical, thoracic, and lumbar spine sections, and the sacrum and coccyx bones. The cervical section of the spine is made up of the top seven vertebrae in the spine, C1 to C7, and is connected to the base of the skull.
Is the spine divided into 5 regions?
As mentioned above, our vertebrae are numbered and divided into five regions: cervical, thoracic, lumbar, sacrum, and coccyx.
What are the 3 areas of the spine?

Which spinal nerves affect which parts of the body?
The nerves of the cervical spine go to the upper chest and arms. The nerves in your thoracic spine go to your chest and abdomen. The nerves of the lumbar spine then reach to your legs, bowel, and bladder. These nerves coordinate and control all the body’s organs and parts, and let you control your muscles.
What is the lower part of your spine called?
The bottom of the spine is called the sacrum. It is made up of several vertebral bodies usually fused together as one. The remaining small bones or ossicles below the sacrum are also fused together and called the tailbone or coccyx.
What absorbs shock in the spine?
The intervertebral discs are soft structures which act as shock absorbers between each of the vertebrae (bones) in the spine. A single disc sits between each vertebra.
At what age will the five bones of the sacrum start fusing together?
It is made of five fused vertebrae numbered s1 through s5. These five vertebrae are separate in children and young people. They begin to fuse in late adolescence and early adulthood and are usually fully fused by age 30.

Where is L7 on your spine?
The seventh lumbar vertebra (L7) or its caudal articular processes are considered the most frequent sites of fractures, with fracture occurring more commonly than dislocation (Flatt et al., 1974).
