Skeletal System

You are about to read three things about the skeletal system so tou might want to pay attention. You will learn about bone cancer and the importance of the pelvis and ribcage.

Bone Cancer

First thing about the skeletal system is bone cancer. Bone cancer is rare. Bone cancer can begin in any bone in the body , but it most commonly affects the long bones of the arms and legs. Several types of bone cancer exist. Some types of bone cancer ocur in children , while others affect mostly adults. Pain is the most common symptom of bone cancer , but not all bone cancer causes pain. One persistent or unusual pain or swelling in or near a bone can be caused cancer or by other conditions. It is important to see a doctor to determine the cause.

Bone Cancer

Pelvis

Pelvis

The second thing about the skeletal system is the importance of the pelvis. The pelvis is a ring of bones in the lower trunk of the body , which is by the coceyx and the hip bones. The pelvis portects abdominal organs such as bladder , rectum ,and in women, the uterus. The pelvis is made up of three hip bones , which are joints to the sacrum at the back. The hip bone curves forward to join th pubic symphysis at the front. The symphysis pubis is a cartilainous union between both side of the pelvis anteriorly.

Ribcage

The last thing about the skeletal system is the importance of the rigcage. The ribcage has three important furctions portection ,support and respiration. The ribcage supports the upper body , protects organd including the heart and lungs ,and assists with breathing. Rib injuries include bruises , torn cartilage and bone fractures. Chest trauma may also cause life threatening injuries such as a punctured lung or a ruptured aorta. Common causes of rib injuries include motor vihicle accidents and falss. Treatment aims to relieve pain while the injuries heals.

So know you know three things about th skeletal system you know what is bone cancer and how you can get it and know you know why the pelvis is important and the ribcage.
