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 explain how muscles work together to move bones at joints.
Key Notes
- Bones meet at joints.
- Muscles can move bones.
- Muscles can only pull, by contracting, and cannot push.
- Some muscles work together in antagonistic pairs to move bones at a joint.
Vocabulary To Learn
- tendon: A tendon attaches muscle to a bone.
- ligament: A ligament holds two or more bones together at a joint.
- joint: A joint is where two or more bones meet.
- cartilage: Cartilage is a strong, smooth tissue that is found inside a joint.
- antagonistic muscles: Antagonistic muscles work in pairs to move a bone at a joint.
Common Mistakes To Avoid
- Thinking that muscles can push bones (when in fact they can only pull).
3 Quick Questions (With Answers)
1. Explain the scientific idea in this lesson using two key points.
Bones meet at joints. Muscles can move bones.
2. Define this scientific word and use it in context. 'tendon'
A tendon attaches muscle to a bone. Include the word in a full scientific explanation, not as a single label.
3. Correct this common scientific misunderstanding.
Mistake: Thinking that muscles can push bones (when in fact they can only pull). Correction: The lesson makes clear that muscles can only pull bones, and work in antagonistic pairs to pull bones in opposite directions.
