Functions of the vertebral column in humans

30 Mar

ImageThe vertebral column or backbone, in humans, is a column of bones usually consisting of 24 vertebrae and 9 fused vertebrae in the coccyx and sacrum.
Including the five bones that fuse together to form the sacrum and the four bones that form the tail bones, there are normally 33 bones in the spine.
The upper 24 bones consist of 7 cervical, 12 thoracic and 5 lumber vertebrae.

The functions of the backbone include the protection and housing of the spinal cord inside its spinal canal. The vertebral column is also responsible
for flexibility and easy movement of the human body, permitting the bending of the trunk in multiple directions. Although, there is a limitation of
movement between the vertebrae bones themselves. The backbone also provides a point of attachment for the rib bones and the torso muscles, especially
the muscles at the back. The backbone also helps to support the body’s frame, ensuring that it remains upright and is responsible for connecting the
head to the rest of the body
