CAIE IGCSE Biology EXTENDED 11.1.6 Internal & external intercostal
Practise recognising intercostal muscles in breathing-system diagrams and naming the muscles that move the ribs.
How this is tested
- label external intercostal muscles accurately on a diagram of the thorax
- state that intercostal muscles are responsible for moving the ribs during ventilation
