The Spine (more accurately reffered to as the Vertebral Column) is made up of 33 Vertebrae joined by Inververtebral Disks. These vertebrae are split into 5 regions accoording to their shape (only some details change but general structure is constant) and where they are in body. The uppermmost region is called the Cervical (Ser-vy_cl) region and it contains the top 7 vertebrae. This region is where the upper Lordosa (curve pointing forwards) is seen and it is contained entirely within the head and neck. Within this region are two very cpecial vertebrae called Atlas and Axis. The atlas is the uppermost and it articulates with a part of the Skull called the Occipital Condyle. At this joint flaexion and extension can take place (ie nodding). The next vertebrae down is the Axis which form a unique joint type called a Synovial Pivot Joint. Here rotation around a projection od the axis allows the head (and the atlas) to rotate (as in shaking the hea). The region below this is called the Thoracic Vertebrae which contains the next 12 vertebrea. Its shape is a Kephosa (curve pointing backwards) that is enlarged in a "humped back" or Kephosis (the pleural or kephosa is kephoses with an E). This region is contained entirelt within the thorax as the name suggests. Down from this is the Lumbar Region within which there are only 5 vertebrae. This region forms the lower lordosa and is contained within the Abdomen. Up till now all the vertebrae have been separate bones connected by intervertebral disks but the next to regions have their vertebrae fused together (although not between the two regions). The Sacrum looks like one bone but is actually the next 5 vertebrae all fused together. It is the part that jsits between the posterior parts of the left and right pelvis bones, joined to them by synnovial plane type joints. The final region is the Coxxyxwhich contains 4 more tiny vertebrae that have again fused together to form a single structure. This is the region that used to lead on to form the tail until we evolved not to have one. The combination of the coxxyx and the sacrum makes the lower kephosa.

The spine, also known as the vertebral column or spinal column, is a column of 26 bones in an adult body – 24 separate vertebrae interspaced with cartilage plus the sacrum. The last is the coccyx which is not interspaced with cartilage. The spinal column is divided into 5 different areas grouped into seven cervical vertebrae in the neck, twelve thoracic vertebrae (corresponding to each pair of ribs), five sacral vertebrae which are fused together to form one bone called the sacrum.
The sacrum is the bone of the spinal column toward the caudal end right below the seventh lumbar vertebrae and directly above the coccyx. It is triangular in shape and comprised of five bones that are fused together.
The five types of vertebra are the:cervical vertebrae (neck)thoracic vertebrae (chest)lumbar vertebrae (back)sacral (pelvis)coccyx (tailbone)

The spinal cord is protected by the vertebral column or spinal column. The vertebral column is a collection of individual bones called vertebrae that encase and protect the spinal cord. The vertebral column is divided into three parts: seven cervical (neck) vertebrae at the top, twelve thoracic vertebrae in the midback, and five lumbar vertebrae in the lower back. Below the lumbar vertebrae, but not protecting the spinal cord, are the sacrum and coccyx (tailbone).
The Axial Skeleton is composed of five parts 1) the human skull 2) the ossicles of the middle ear 3) the hyoid bone of the throat 4) the rib cage 5) the vertebral column.
The vertebral column (backbone or spine) of a human supports approximately half the weight of the human body while muscles support the other half. The vertebral column comprises four regions: cervical, thoracic, lumbar, and sacral (or pelvic). Each region of the spine comprises various vertebral bodies separated by discs. The vertebral bodies act as a support column to hold up the spine. The vertebral column protects sensitive nerve roots while providing mobility. The vertebral column is subjected to various types of loads, particularly when a person is seated. Excessive loading of the spine over time often leads to back pain, particularly caused by improper posture while seated. The vertebral column is made up of 33 ring like bones calle vertebrae.It is divided into five main regions -- 7 cervical vertebrae(C1-C7) in the neck,12 thoracic (T1-T7) in the chest, 5 lumbar (L1-L5) in the lower back, 5 fused sacral vertabrae in the sacrum and 4 fused coccygeal vertebrae. The 26 movable vertebrae are linked by movable joints. In between the bones of each joint is an intervertebral disc which is a springy pad of tough, fibrous cartilage that squashes when pressure is exerted absorbing any shocks. Ligaments and muscles around the spine provie stability and assist with controlling muscles.
