Human Skeleton and Body Parts

The Human skeleton provides support, protection, surfaces for muscles attachments, enables movement, stores minerals (calcium and phosphate) and is a site for the production of red blood cells.

Human Skeleton and Body Parts

Humans require support to bear their body weights as well as enable them to move about in their environment. The skeletal system in humans provides them with support and the ability to move about. Three types of skeleton found among these organisms are the hydrostatic skeleton, the exoskeleton and the endoskeleton.

Axial Skeleton

Axial skeleton consists of the skull, cervical vertebrae, thoracic vertebrae, lumbar vertebrae, sacrum, coccyx, sternum and ribs.

a)     Skull – The skull is made up of the cranial bones (8 pieces). The cranial bones are joined together by the suture and are immovable. The skull protects the brain. The facial bones protect the sensory organs like the eye, the ear and the nose.

b)    Vertebrae – The vertebrae which numbers 33 are connected together by ligaments and cartilaginous discs to form the vertebral column which encloses and protects the spinal cord.

c)     Sternum – The sternum is a flat piece of structure made of cartilage. Three bones are joined together to form the sternum.

d)    Ribs – 12 pairs of ribs together form the rib cage which plays an important role in the breathing mechanisms. The first seven pairs of ribs known as the true ribs are connected to the sternum via cartilage at the anterior end.

The following three ribs known as the false ribs are connected to neither the seventh rib while the last two ribs (11th, 12th ribs) are connected to the sternum nor other ribs. These are referred to as the floating ribs.

    Excellent article. I have a son born with spinabifida and through the years have collected many books on anatomy. This is so concise it rolls them all into one.

    I’ve bookmarked the page.
