Although in all three fossils the transitional vertebra at which the articular facets change orientation seems to be at Th11, this is equal to a large percentage of modern humans. Indeed, a modal number of five lumbar vertebrae, as in modern humans, is more compatible with evolutionary ...
Each vertebral segment is made up of two bony vertebrae with a spinal disc in between. The spinal disc is also susceptible to a number of problems and may often be a source of pain, as discussed on the next page. Pagination Next Page: Spinal Discs Pages: 1 2 3 4 5 6 7 Dr. ...

Within the cervical region, atlas (C1) and axis (C2) are very different to the rest of the vertebrae in structure; they form an atlantoaxial joint and provide most of the head rotation motion (Mcminn et al., 1998). A typical cervical vertebra (as shown inFig. 22.1B) has a flat slig...

Vertebrae are stacked on top of one another to form the spinal column. The spinal column is the body’s main upright support. From the side, the spine forms three curves. The neck, called the cervical spine curves slightly inward. The middle back, or thoracic spine curves outward. The ...
the spinal column of the child contains more vertebrae than the adult, in whom a number become fused into two immovable bones, the sacrum and the coccyx, forming the back of thepelvis. The 24 movable vertebrae are the 7 cervical (neck), 12 thoracic (back of chest), and 5 lumbar (loin...
The spinal column is the axis of the skeleton; the skull and limbs are in a sense appendages. The vertebrae also provide the protective bony corridor (spinal canal) through which the spinal cord passes; they can move to a certain extent and so give flexibility to the spine, allowing it ...
