Spine Bones
The picture to the left points out the main components of the Spine. The bones we will be focusing on are : cervical vertebrae, thoracic vertebrae, lumbar vertebrae, sacrum, and coccyx.
Cervical Vertebrae: Cervical vertebrae are the first vertebrae of the spinal column that make up the seven vertebral bones. The cervical vertebrae bones are primarily responsible for protecting the spinal cord and supporting the body.
Thoracic Vertebrae: Thoracic vertebrae create the middle section of the spinal cord directly following the cervical vertebrae. There are 12 vertebrae that make up this section and the vertebrae increase in width and size as you move down the spine. Spinal cord protection is the main function of the thoracic vertebrae.
Lumbar Vertebrae: Lumbar Vertebrae make up the third section of the spinal cord proceeding the thoracic curve. There are 5 vertebrae in this section and the vertebrae increase in size moving down the spinal cord. The lumbar vertebrae are responsible for protection of the spinal cord as well as supporting much of a person's weight and allowing for a lot of body motion.
Sacrum: In a child the sacrum is made up of five individual bones but as we grow up the bone fuses into one bone. The sacrum is a triangular bone and it serves to protect and support the body.
Coccyx: The coccyx makes up the last piece of the spinal column. The sacrum provides support for sitting and is an attachment site for many bones and ligaments.
