The Sacrum (diagram below) consists of five fused vertebrae in a wedge like shape at the bottom of the vertebral column.

The human spine consists of vertebrae that help support the back muscles, protect the spinal column, and provides the rod function for the axial skeleton (Mays 1999). The Atlas bone (C1) lies between the cranium (connecting with the condyles of the occipital bone) and the Axis vertebrae (C2).

The Human Bone Manual. Please note that there are variations depending on the class of vertebrae under discussion. The Archaeology of Human Bones.

The Coccyx (diagram below) articulates distally to the Sacrum, and consists of 3 to 5 fused elements (variation is common). Important changes in the morphology and shape of these elements can be noted, thus each part can be ascertained to the differing thirds of the spine (White & Folkens 2005). The normal cervical vertebrae include interlocking vertebral bodies, with saddle shaped superior and inferior surfaces; alongside this the canal (see below) is triangular and of a similar size to the vertebral body (Mays 1999). The incipient factor is the enzymatic breakdown of the cartilage matrix, and affects the bone in the following ways. It is the vestigial tail, and highly variable in shape. It consists of the body, the lesser horns and greater horns, as can be discerned in the diagram below (White & Folkens 2005: 155). 1. Scoliosis and Segmentation Defects of The Vertebrae. Once again, care should be taken with handling, and it is unlikely all the elements would survive. ‘Formation of new bone (after mixed signals from enzymes) around the margins of the joint; often called marginal ostephytes. White, T. & Folkens, P. 2005. The atlas and axis vertebrae are the two most superior bones in the vertebral column, and they are part of the seven cervical vertebrae. The production of eburnation, a highly polished area on the joint surface, usually sharply demarcated from the non-eburnated surface.

Without them, head and neck movement would be impossible. Cervical, Thoracic & Lumbar Vertebrae & Anatomical Features. Atlas vs Axis Vertebrae.

They are the largest of all the unfused vertebrae, and should be easily identifiable by their size and features (larger spinous process, vertebral bodies, & smaller transverse process and lumbar arches) (White & Folkens 2005: 178).

The key difference between atlas and axis vertebrae is that the atlas vertebra is the topmost vertebra which holds the skull while axis vertebra is the second topmost vertebra which provides an axis to rotate the skull and atlas vertebra when the head moves side to side.. Cervical vertebrae are the vertebrae in the neck region, immediately below the skull. The main difference between atlas and axis vertebrae is that atlas is the first cervical vertebra, which supports the skull whereas axis is the second cervical vertebra, which forms the pivot upon the atlas. Most people tend to call them either axis or atlas interchangeably because of the proximity of the two bones, as well as their relatedness in function. Subscribe To These Bones Of Mine By Email! The axis is the second cervical vertebra; it has what is called the odontoid process about which the atlas rotates.
