What are facts about about the skeletal system?

Answer 1

the human and giraffe have the same amount of bones in their body, but the giraffe has a much, MUCH longer vertebrae.

Some interesting facts of the skeletal system are that men's bones are generally thicker than women's.

bones get lighter as you age.

bones move when muscles contract.

the bone sticking out the end of the backbone (on a side view) is the remains of our tail.

the longest bone is the femur(upper thigh).

Erythrocyte production switches from long bone (e.g. femur).

bone marrow in infants to membranous bone e.g. vertebra/sternum in adult life.

it protects delicate organs such as the brain (By skull), or heart and lungs (By ribs), etc.

Your finger bones are considered long bones, even though they are very short.

Over half of the body's bones are located in the hands and feet.

About 97% of known species, do not have a backbone.

The skeletal system is vital for providing shape, support and protection for the human body. The system is made up primarily of bones. Teeth are a part of the skeleton but aren't considered bone. Bones need regular exercise to stay as strong as possible. A typical bone has an outer layer of hard or compact bone, which is very strong, dense and tough. Inside this is a layer of spongy bone, which is like honeycomb, lighter and slightly flexible. In the middle of some bones is jelly-like bone marrow, where new cells are constantly being produced for the blood.

An adult skeleton has 206 bones while you are born with 236 bones .

• Babies are born with more than 300 bones in their body. As we grow into adults, some of the bones grow together - an adult skeleton has 206 bones.
• Bones are alive! They are growing, living tissue. Bones are constantly renewed throughout our lives through a process called resorption. A process called formation then adds to the bones.
• When children are little, their skeletons re-new themselves every 2 years!
• Bones are actually hollow - the inside of a bone is filled with bone marrow, which is then protected by the hard, outer surface of the bone.
• Oxygen is carried around our bodies by red blood cells, which are made by the bone marrow.

• The biggest bone is in the leg. It is called the femur or thighbone.
• The strongest bone in the skeleton is the jawbone.
• Over half the bones in the skeleton are found in the hands and feet. The hand alone has 27 bones - in each one.
• A broken bone will take about 12 weeks to heal.
• Your skeleton increases about seven times in mass through your childhood, so this is the vital time for it to get plenty of bone building calcium.

The human skeletal system not only provides the structure to stand up straight, but also protects all the important and delicate organs inside our body. The brain, a mass of spongy matter, is protected within the strong bony case called the skull. The vertebral column protects the complex bundle of nerves or the heart and lungs are protected by a bony ribcage.

The smallest bone in the body is the stirrup bone, located deep inside the ear. It is just a little larger than a grain of rice.

The largest bone in the body is the pelvic bone.

Our bone is six times stronger than steel if both are of the same weight.

Bones do not move on their own, they need the help of the muscles attached to the bones.

14 bones make up your face.

The only bone without a joint is your body is the hyoid bone present in your throat.

Answer 2

IN the human body you have 206 bones in your body
