                                         The Introduction

My introduction own the skeletal system is The axial skeleton consists of bones of the head, neck and vertebral column and rib cage, which is in all 80 bones. The axial skeleton supports and protects organs in the dorsal (posterior) and ventral (anterior) body cavities. It provides surface area for muscle attachment.


Inside every person is a skeleton, a sturdy framework of 206 bones. The skeleton protects the body's organs, supports the body, and provides attachment points for muscles to enable body movement. Bones also produce blood cells and act as a storage site for minerals such as calcium and phosphorus. Read more:

  • Osteoporosis: This is a disease in which the bones become fragile and prone to fracture.
  • Leukemia: This is a cancer of the white blood cells.
  • Osteopenia, osteitis deformans, and osteomalacia: Similar to osteoporosis, these are other types of bone loss.

                                                 5 facts

The longest bone in the body is called the femur, which connects the pelvis to the knee.The smallest bone in the body is in the middle ear, and is called the stapes, which is latin for stirrup (this bone is shaped like a stirrup). It is only 0.1 to 0.13 inches long!Bones are broken down and remade constantly, just like skin. In fact, all of the bones are slowly replaced until they are new bone once every 7 years!The insides of some bones contain special material called bone marrow. Bone marrow has lots of cells which make red blood cells. Red blood cells carry oxygen all over the body. Every second, bone marrow produces two million red blood cells!The best way to look at bones is with a special photo called an X-ray. X-rays help tell doctors where a fracture is located, so they know where to put a cast.
