Skeletal System Functions Flashcards

1️⃣ Familiarise yourself with the flashcards:

  • Look through all the flashcards to see what's on both sides.
  • Make sure you understand the information on each card. If something's unclear, click the link to the revision notes at the bottom of the page for more details.

2️⃣ Test yourself:

  • Look at the question or prompt on each card and try to remember the answer before flipping it over.
  • Check the answer and make a note of any cards you find challenging and need to go over more.

3️⃣ Consistently Review and Practice:

  • Use spaced repetition: spend more time on the cards you struggle with and go over them more often.
  • Regularly review all the flashcards to help you better understand and retain the information over time.

Note: We may include questions that have multiple correct answers. It's useful to remember specific examples to understand these concepts better.

What does the skeleton do to support the body?

It gives the body shape and holds you upright by supporting soft tissues.

How does the skeleton protect vital organs?

Hard bones like the cranium and ribs shield the brain, heart and lungs from impact.

How does the skeleton help movement?

Bones meet at joints so muscles can pull to move the body.

What does structural shape and posture mean?

The skeleton provides your body’s frame and helps you keep good posture when standing or sitting.

What is weight-bearing as a function of the skeleton?

Bones are strong enough to carry your body weight during standing, running and jumping.

What is leverage in the skeletal system?

Bones act as levers, letting small muscle forces create bigger or faster movements.

What are points for muscle attachment?

Sites on bones where tendons attach muscles, allowing muscles to pull and move joints.

Where are blood cells made in the skeleton?

In bone marrow, for example in the femur, ribs and sternum.

Which blood components are produced in bone marrow?

Red blood cells, white blood cells and platelets.

Which minerals are stored in bones, and why?

Calcium and phosphorus; they make bones strong and help muscle contraction.
