The human skeleton

Human skeleton and muscles

Unit Summary

This unit investigates the structure and functions of the human skeleton, including support, protection, movement, and blood cell production. Explore biomechanics, the interaction of muscles and the skeleton, and antagonistic muscles while measuring muscle force.

Lesson Summary

You will learn to describe the role of the human skeleton in support, protection and making blood cells.

Key Notes

  • The human body contains a skeleton made up of bones.
  • A joint is where two or more bones meet.
  • The skeleton supports the body and provides protection for organs and tissues.
  • Bones are made of living tissue made up of cells.
  • Red and white blood cells are made in the bone marrow.

Vocabulary To Learn

  • bone: Bones are living tissues that are made up of cells.
  • skeleton: The skeleton is made up of bones. It provides support, protection and movement.
  • joint: A joint is where two or more bones meet.
  • tissue: A tissue is a group of similar cells working together for the same function.
  • red blood cell: Red blood cells carry oxygen around the body.

Common Mistakes To Avoid

  • Bones are not living; bones are not made up of cells.

3 Quick Questions (With Answers)

1. Explain the scientific idea in this lesson using two key points.

The human body contains a skeleton made up of bones. A joint is where two or more bones meet.

2. Define this scientific word and use it in context. 'bone'

Bones are living tissues that are made up of cells. Include the word in a full scientific explanation, not as a single label.

3. Correct this common scientific misunderstanding.

Mistake: Bones are not living; bones are not made up of cells. Correction: This lesson explores the idea that bone is a tissue made up of cells, and that it is living (because it can heal).
