The skeleton is designed in such a way that the delicate parts of the body are protected. These parts are major organs‚ the brain is protected by the skull‚ the lungs and heart are protected by the ribs and the vertical column protects the spinal cord. For example you will see this happen in many sports such as boxing‚ the skull protects the brain from impact of a punch during a fight. Support/ Shape: The skeletal system gives the human body structure. It supports the internal organs

human body. The spine serves various purposes. It consists of about thirty- three separate bones called the vertebrae which come from the Latin word “to turn”. The Spine which is also known as the vertebra supports our weight‚ holds us in a vertical position and supports our body movements. The vertebra plays an important function by protecting the spinal cord and nerves as they connect to all the other parts of the human body. There are four separate curves in a normal spine. Each curve contains

At any given time‚ 10 percent of the adult population has neck pain and it is the second leading cause of lost time from work behind low back pain‚ with less than 1 percent developing neurologic deficits and requiring surgical intervention. Most of the patients do recover with conservative therapy regardless of the underlying etiology of pain. Patients clinically present for a number of contributing factors and despite the cause‚ end up recovering well with conservative therapy. The development

A vertebral column extends from your skull to your pelvis. It is made up vertebrae‚ which are serrated by masses of Fibrocartilage which are called intervertebral disks. The disks are connected by ligaments. An infant has 33 separate bones in the vertebrae column; however‚ the adult column has 26 bones‚ because four form into the coccyx. While the other five bones form the sacrum. ( Hole‚ 210 )The vertebral column not only supports the head and the trunk of the body‚ but it’s also flexible enough
