Bone facts

The parts of the human skeleton work as a system for support, protection, movement and the production of new blood cells

. Bones are living organs with a blood supply. They grow and can repair themselves

too.

Our skeleton is made of 206 bones. Babies have over 300 bones which eventually fuse (grow together). Calcium, phosphorous and vitamin D make the bone strong but slightly flexible. If you don’t get enough nutrients bones become brittle and break easily. The nose is made of cartilage, not bone, which is why skulls have no noses.

The skeleton

Bone diseases:

We need the skeleton for:

Support

ProtectionMovementBloodThe skeleton provides a frame to hold your body upright and keep your organs in place. The skeleton also protects your major organs.Most bones are joined to each other by flexible joints. Muscles are needed to move bones attached by joints.Red blood cells are made in the bone marrow found in most bones..

Fibrodysplasia

ossificans

progressiva (FOP)

Key words:

Joints:

Places where bones meet.

Bone marrow: Tissue found inside some bones where new blood cells are made.Ligaments: Connect bones to bones in joints.Tendons: Connect muscles to bones.Cartilage: Smooth tissue found at the end of bones, which reduces friction between them.Muscle: A tissue found in the body made up of bundles of fibres that move joints by tightening (contracting) and relaxing.Antagonistic muscle pair: Muscles that work in unison (together) to create movement. For example the bicep and triceps in your arm.

Types of joints

Antagonistic pairs

Muscles can only pull and can’t push. This means two muscles have to work together at a joint. This is called an Antagonistic

pair.

Synovial jointSynovial Fluid fills the space between the ends of bones in a joint. It acts as a lubricant and shock absorber in the joint.Cartilage is a strong and spongy tissue. It

in joints to protect the end of the bone. When we move, cartilage in our joints acts to reduce friction to protect our bones.

At your elbow and knee is a hinge joint, and this movement in one plane.Hinge

joints

Fixed joints are found in the skull, The skull is made up of plates of bone that are fused together.

A ball and socket joint is made up of a round end of one bone that fits into a small cup-like area of another bone.It allows only rotational movement such as moving your head from side to side as if you were saying 'no'.Pivot jointsBall and socket joints
