Key learning points
- The human body contains muscles.
- Muscles are a type of tissue made up of specialised cells.
- Muscles can contract and relax.
- Muscles need sugar and oxygen to contract.
- Different types of muscle have roles in organ systems, including cardiac muscle, smooth muscle and skeletal muscle.
Common misconception
Thinking that muscles are only found attached to the skeleton to move our limbs, and nowhere else.
Discussion of three types of muscle, where they are found, and their roles.
Keywords
Muscle - A living tissue made up of muscle cells.
