    Presentation Transcript
    1. Human Skeletal System The framework of the human body

    2. Structure There are 206 individual bones in the human skeletal system. The bone structures consist of long bones, short bones, flat bones, irregular bones, sesamoid bones, and sutural bones. There are 22 bones in the head There are 33 bones in the spine. The thorax (chest) has 12 pairs of ribs.

    3. The skeleton is divided into two portions: • Axial skeleton: the bones of the skull, the vertebral column and the rib cage. • Appendicular skeleton: the bones of the upper and lower limps and the bony girdles.

    4. Function Skeleton is the framework of the human body that supports and gives attachment to softer tissues. Skeleton in the skeletal system helps to protect internal organs and the spinal cord. Larger bones with red bone marrow help produce blood cells. Bone tissues provide several minerals, such as Calcium and phosphorus, when needed. Muscles are incorporated with bones, meaning that when the muscles move your bones move. Yellow bone marrow is an important chemical energy reserve.

    5. Arthritis Arthritis is inflammation on one or more joints. A joint is the point where two bones meet. The cartilage, which protects the joint, breaks down, causing the bones to rub against each other. This process is very painful, causes swelling, and stiffness. Arthritis is a common disease in the skeletal system. There are hundreds of different types of arthritis. However, osteoarthritis is the most common one.

    6. What can cause Arthritis…

    7. Osteoarthritis Osteoarthritis is caused by tearing on the joints. Aging is said to be the primary cause for this disease. By age 70, almost everyone has symptoms. Some graver than others. The main symptoms are: 1. Stiffness in the joints 2. Pain in the joints

    8. Treatment for Osteoarthritis • Although osteoarthritis cannot be cured, the symptoms can be controlled. • Treatments for osteoarthritis are: 1. Surgery 2. Medications 3. Exercise 4. Physical therapy 5. Injections

    9. Facts There are 206 individual bones in the human skeletal system. The skull is most complex part of the axial skeleton. Bones are dead, but in the body they are alive. Your skeleton helps protect your internal organs and bone tissues. Your skeleton consists of 200 joints. Your teeth are part of your skeletal system, but they are not a BONE The femur is the largest bone in your body and about ¼ of your height. The most broken bone is the collar bone. The hyoid bone is the only bone that is not attached to any other bones. YOUR BONES ARE BEAUTIFUL!!!
