××Weirdest Disease of the Human Bone: Disappearing Human Bone Disease:

 

The clinical terms for this disease is massive osteolysis. It’s more commonly known as

See Also:

Gorham’s disease . Regenerating bone after a fracture is overtaken by the process of absorbing bone and the bone is broken down into almost nothing. The bone just kind of disappears, as the name suggests. What’s perhaps most mysterious is that a number of cases of Gorham’s have ended in spontaneous remission . The disease itself disappear

×× Broke the Most Bones over a Lifetime: Evel Knievel

 

Evel Knievel (USA, b. Robert Craig Knievel), the pioneer of motorcycle long jumping exhibitions, had suffered 433 bone fractures by end of 1975. In the winter of 1976 he was seriously injured during a televised attempt to jump a tank full of sharks at the Chicago Amphitheater. He decided to retire from major performances as a result.

×× Smallest Bone in the Human Body: Stirrup Bone

 

The smallest bone in the human body is the stirrup bone, the stapes, one of the 3 bones that make up your middle ear; measuring 2-3 millimeters. It is shaped like a “U.” It is the innermost bone that receives sound vibrations and passes them along to the cochlea to eventually be interpreted by the brain.

××. Biggest (and Strongest) Bone in the Human Body: Femur

 

The femur is the strongest bone in the human body. It extends from the hip to the knee. It can resist a force of up to 1,800 to 2,500 pounds. Only events of a large amount of force can cause it to break, such as by a car accident or a fall from an extreme height, taking months to heal.

×× Body Part with the Most Bones: The Hands

 

The hands have the most bones — 27 in each hand.The hands and feet together make up more than half the bones in the human body. There are 206 bones in the human body; 106 of these are in the hands and feet (27 in each hand and 26 in each foot).

×× Most Commonly Broken Bone:

The Ankle!

Even more common than breaking a toes is spraining or breaking your ankle. It happens almost everywhere: on the field of play, on a hiking trail or trying not to trip over children’s toys. There is a difference between a sprained and broken ankle. Ankle fractures and sprains are both often accompanied by tendon damage.

×× Most Fragile Bone in the Body:

The Toe Bones

 

The small toe bones break the easier and most often. Almost everyone has broken a toe, even a small one, in their life. And there’s really you can do about it, but let it heal.

×× Most Common Form of Bone Surgery: Arthroscopic Surgery

 

Arthroscopic procedures on the knee increased 49% between 1996 and 2006. Arthroscopy is a surgical procedure by which the internal structure of a joint is examined for diagnosis and/or treatment using a tube-like viewing instrument called an arthroscope. Arthroscopy can be helpful in the diagnosis and treatment of many noninflammatory, inflammatory, and infectious types of arthritis as well as various injuries within the joint.

××Most Common Bone Disease: Osteoporosis

 

Osteoporosis is the most common bone disease, which is characterized by low bone mass and deterioration of bone structure. Osteoporosis can be prevented, as well as diagnosed and treated. Low bone mass is when bones lose the minerals that make them strong, especially calcium, which makes them weak and fracture easily.

×× Most Common Forms of Bone Cancer: Osteosarcoma

 

These are some of the most common types of bone cancer:

Osteosarcoma start in bone cells and found most often in the knee and upper arm. It is diagnosed most often in teens and young adults.

Ewing’s sarcoma is seen in younger people between the ages of 5 and 20. It most commonly occurs in people’s ribs, pelvis, leg, and upper arm.

Chondrosarcoma occurs most often in people between 40 and 70. The hip, pelvis, leg, arm, and shoulder are common sites of this cancer, which begins in cartilage cells.

Although almost always found in bone, multiple myeloma is not a primary bone cancer. It is a bone marrow cancer. Bone marrow is the soft tissue inside bones.

At birth the human skeleton is made up of around 300 bones. By adulthood, some bones have fused together to end up with 206 bones.

Human bones grow continually from birth till our mid 20’s. Our skeleton’s bone mass is at its maximum density around the age of 30.

If broken our bones will re-grow and repair themselves. Often doctors will place a cast on splint to make sure these bones repair straight and true.

The axial skeleton part of the human skeleton has 80 bones. It includes the vertebral column, the rib cage and the skull and helps us maintain our upright posture, by spreading the weight in the head, and upper areas down to the lower areas near the hips.

The appendicular skeletal section of our skeleton has 126 bones. It includes the pectoral (shoulder) girdles, the pelvic girdle and the bones of the lower and upper limbs. Its function is for movement of the body and to protect some organs.

The human skeletal system has six major functions including the production of blood cells, for support, for movement, for protection, for storage of ions and endocrine regulation.

The longest bone in the human body is the thigh bone called the femur.

The smallest bone found in the human body is located in the middle ear. The staples (or stirrup) bone is only 2.8 millimetres (0.11 inches) long.

Like our skin , the human body’s bones are also constantly worn down and re-made, to the point where every 7 years we essentially have a new bone.

The area of our body with the most bones is the hand, fingers and wrist where there are 54 bones.

Our teeth form part of the skeletal system, but are not counted as bones.

There a just a few differences between human male and female skeletons. The female skeleton is generally slightly smaller and the pelvis bones differ in shape, size and angle in order to assist with child birth.

The majority of human bones have a dense, strong outer layer, followed by a spongy part full of air for lightness, while the middle contains a soft, flexible, tissue substance called bone marrow.

Bone marrow makes up 4% of a human body mass. It produces red blood cells which carry oxygen all over the body. Marrow is also produces lymphocytes, key components of the lymphatic system, which support the body’s immune system.

Calcium is very important for our bones and helps keep them strong and healthy.

The areas where our bones meet are called joints. The joints in our cranium have no movement while our hip joints allow for a wide range of movement.

Bones are held in place at joints by muscles and also tissues called ligaments. Another type of tissue called cartilage covers each bone joint surface area to prevent the bones rubbing.

The medical branch of learning about the human skeletal system is called Orthopedics.

There are a number of skeletal disorders, osteoporosis is a bone disease that increases the chance of fractures, scoliosis is a curvature of the spine, while arthritis is an inflammatory disease that damages joints.
