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. Thoracic vertebrae are larger and stronger than cervical vertebrae but are much less flexible. The 5 sections of the spine or vertebral column are the cervical, thoracic, lumbar and sacrum which includes the coccyx. 12 thoracic vertebrae are next, which are . As mentioned above, our vertebrae are numbered and divided into five regions: cervical, thoracic, lumbar, sacrum, and coccyx. The answer is C, 7. 5. 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. Each vertebra is composed of several parts that act as a whole to surround and protect the spinal cord and nerves, provide structure to the body and enable fluid movement in many planes. Lumbar Vertebrae These are the 'fattest' of the vertebrae due to the big body of each bone and this section is made up of 5 vertebrae (abbr. 1? B. In rare instances, a person may have an additional vertebrae. The bones of the vertebral column are classified as which type of bone? How many vertebrae make up a spinal segment? How many cervical vertebrae are there? sacrum - 5 fused vertebrae. 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. As we grow into adulthood, most individuals will have about 24 vertebrae as the vertebrae at the bottom end of the spine fuse together. The discs are located between each vertebra allowing for bending, twisting and shock-absorption. It consists of various groups of vertebrae and is divided into .
