How does the skeleton help a performer produce movement?

Muscles attach to bones through tendons and pull on them. The bones act as levers, turning about the joints.

How does the skeleton contribute to oxygen transport for an endurance athlete?

Red bone marrow inside some bones produces red blood cells. Red blood cells carry oxygen to the working muscles.

What is the axial skeleton?

The axial skeleton is the central core of the body. The skull, vertebral column, ribs and sternum make up the axial skeleton.

What is the appendicular skeleton?

The appendicular skeleton is made up of the limbs and the girdles that attach them to the axial skeleton. The shoulder and pelvic girdles belong to it.

Questions from this subtopic

Each one with the model answer underneath.

1
What are the main functions of the skeleton?
Model answer
The skeleton supports the body and protects vital organs. The skeleton also provides levers for movement. Bone marrow produces blood cells, and bones store minerals.
2
How does the skeleton protect a performer in contact sport?
Model answer
The cranium protects the brain, and the ribs protect the heart and lungs. The rib cage absorbs part of the impact of a rugby tackle to the chest.
3
How does the skeleton help a performer produce movement?
Model answer
Muscles attach to bones through tendons and pull on them. The bones act as levers, turning about the joints.
4
How does the skeleton contribute to oxygen transport for an endurance athlete?
Model answer
Red bone marrow inside some bones produces red blood cells. Red blood cells carry oxygen to the working muscles.
