Main FunctionSupport

The main job of the skeleton is to provide support for our body.

Without your skeleton your body would collapse into a heap.

Your skeleton is strong but light.

Without bones you'd be just a puddle of skin and guts on the floor.

Types of Bone TissueCartilage

The cartilage has a number of functions such as:

• Holding some bones together.

• Helping in the formation of bones in growing children.

• Preventing the bones from rubbing each other.

Cartilage is a fibrous and rubbery connective tissue found throughout the vertebrate skeletal system.

Types of Bone TissueLigaments

A ligament is a dense tissue that connects bones to other bones to form a joint.

Ligaments are tough bands, slightly elastic, of white connective tissue.

Types of Bone TissueTendons

Tendons are tough pale/whitish cords that attach muscles to bones

Tendons consist of water, type-I collagen, cells called tenocytes, minor fibrillar collagens, fibril-associated collagens and proteoglycans.

Types of Bone TissueFlat bones

Flat bones also provide most of the red blood cell production within the body.

Flat bones are bones that are made of two layers of compact bone with porous bone between them.

Types of Bone TissueCompact bone

Compact bone being to provide strength and protection to the bone.

Due to its function, compact bone is also referred to as strong bone.

Types of BonesLong bones

They help in movement using the muscles that control bone position and orientation.

long bones provide shape for our bodies and also host the vital organs.

Types of BonesShort bones

Short bones do not usually help provide much movement but are main there for supporting other larger bones.

The most common short bones can be found in the feet and hands.

Types of Bone TissueSpongy bone

The spongy bone is important for metabolic activity, such as the exchange of calcium ions in the body due to its soft structures.

Spongy bones are commonly found at the end of long bones. The bone marrow normally fills up the spaces in between these bones.

DiseaseOsteoarthritis

Cause: There are several different ways to develop the bone infection of osteomyelitis. One is for bacteria to travel through the bloodstream (bacteremia) and spread to the bone, causing an infection.

Symptoms: Signs and symptoms of osteomyelitis include fever chills, arability or lethargy in young children, or pain in the area of the infection.

Treatment: In many cases, osteomyelitis can be effectively treated with antibiotics and pain medications.

fun factsA baby is born with 300 bones. But throughout the

growth years, many of the bones of the skull and spine fuse together.

There are 206 bones in an adult human body.

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

Bones have life. They’re made up of living cells that is why they can grow and repair themselves.

The longest bone, about one-quarter of a person’s overall height, is the femur bone. It’s located in the leg.

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.
