1. What properties of bone prevented Matt from breaks and damage to internal organs? Strength and lightness, calcium and phosphorus. Also, the bones are always adjusting to what you do.

Why do bones not break?

Because a damaged bone has reduced strength and stiffness, it must be repaired, so bone has evolved a system of self-repair that relies on microdamage-stimulated signaling mechanisms. When repair cannot occur quickly enough, low energy stress fractures can occur.

What properties of bone prevent breaks and damage to internal organs?

Bones are hard so that they form a sturdy protection around internal organs. When the body is hit or under pressure the bones absorb the shock or break instead of the internal organs that would be more severely damaged.

How strong is bone What properties of bone give it its strength?

Bones are mostly made of the protein collagen, which forms a soft framework. The mineral calcium phosphate hardens this framework, giving it strength. More than 99 percent of our body's calcium is held in our bones and teeth.

What are the 3 properties of bone?

The fibers are impregnated with inorganic components, including crystals of calcium phosphate, such that using X-ray defraction, they are seen to be organized in a hydroxyapatite pattern (calcium phosphate is 85% by weight) as well as calcium carbonate (10%), and magnesium; by weight, bone is composed of 65-75% ...

What causes a bone to break?

Fractures most often happen when more force is applied to the bone than the bone can take. Bones are weakest when they are twisted. Bone fractures can be caused by falls, injury, or as a result of a direct hit or kick to the body. Overuse or repetitive motions can tire muscles and put more pressure on the bone.

What material is responsible for hardness of bone?

Bone matrix

The hardness and rigidity of bone is due to the presence of mineral salt in the osteoid matrix, which is a crystalline complex of calcium and phosphate (hydroxyapatite). Calcified bone contains about 25% organic matrix (2-5% of which are cells), 5% water and 70% inorganic mineral (hydroxyapatite).

How do bones protect the body?

Although they're very light, bones are strong enough to support our entire weight. Bones also protect the body's organs. The skull protects the brain and forms the shape of the face. The spinal cord, a pathway for messages between the brain and the body, is protected by the backbone, or spinal column.

Which most helps to give bone some flexibility and prevents it from being brittle?

Bones constantly store and release calcium, phosphate, proteins, and other matrix components of bone. Within the matrix, the mineral crystals resist compression but are very brittle. The organic components, such as the collagen fibers and the cells, help give the bone some flexibility.

What does the skeletal system protect?

Protects and supports organs: Your skull shields your brain, your ribs protect your heart and lungs, and your backbone protects your spine. Stores minerals: Bones hold your body's supply of minerals like calcium and vitamin D.

How painful is breaking a bone?

What Happens When a Bone Breaks? It hurts to break a bone! It's different for everyone, but the pain is often like the deep ache you get from a super bad stomachache or headache. Some people may experience sharper pain — especially with an open fracture.

Why does it hurt to break a bone?

Broken bones are painful for a variety of reasons: The nerve endings that surround bones contain pain fiber. These fibers may become irritated when the bone is broken or bruised. Broken bones bleed, and the blood and associated swelling (edema) causes pain.

Why do bones bend before they break?

Why do children's bones bend before they break? The osteoid density of a child's bone is less than an adult's. Juvenile bone is more porous than adult bone because the Haversian canals occupy a much greater part of the bone (Figure 4). This is the principal reason a child's bone can bend more than an adult's bone.

How do you prevent dislocation?

Can a dislocation be prevented?

1. Being cautious on stairs to help avoid falls.
2. Wearing protective gear during contact sports.
3. Staying physically active to keep the muscles and tendons around the joints strong.
4. Maintaining a healthy weight to avoid increased pressure on the bones.

What is the most painful bone to break?

Here's a look at some of the bones that hurt the most to break:

• 1) Femur. The femur is the longest and strongest bone in the body. ...
• 2) Tailbone. You could probably imagine that this injury is highly painful. ...
• 3) Ribs. Breaking your ribs can be terribly distressing and quite painful. ...
• 4) Clavicle.

Is a bone stronger after a break?

There is no evidence that a broken bone will grow back stronger than it was before once it has healed. Although there may be a brief time when the fracture site is stronger, this is fleeting, and healed bones are capable of breaking again anywhere, including at the previous fracture site.

What are the properties of bone?

Bones come in a variety of shapes and sizes and have a complex internal and external structure. They are lightweight yet strong and hard, and serve multiple functions. Bone tissue (osseous tissue) is a hard tissue, a type of specialized connective tissue.

What are two properties of bone?

Chemical composition and physical properties. Bone is a composite of proteins such as collagen and minerals such as calcium. Together these materials give bone a unique combination of strength and elasticity.

What is bone material?

Made mostly of collagen, bone is living, growing tissue. Collagen is a protein that provides a soft framework, and calcium phosphate is a mineral that adds strength and hardens the framework. This combination of collagen and calcium makes bone strong and flexible enough to withstand stress.

How can sports fractures be prevented?

4. Watch out for others.
5. Don't play when you're injured.

How can school injuries be prevented?

Injury prevention efforts can include providing education, designing safe school environments, and the enforcement of safety rules and policies. Keeping students active and safe enables them to participate fully in the school environment.

How we can prevent minor injuries?

Prevention

1. Wear the correct protective equipment. ...
2. Condition and strengthen muscles before play.
3. Stretch before and after play to increase flexibility.
