- The role of the muscular system.
- Muscular System
- Muscles and movement - this allows to move body parts, stabilize joints when movement is happening and protects you vital organs.
- Muscles fall in to 4 different categories
- Flexors - the muscle that bends a limb at a joint by contacting.
- Extensors - the muscle works with and against the flexors and that straightens a limb at a joint contracting.
- Adductors - the muscles that move a limb towards the body.
- Abductors - the paired muscles for abductors, which move a limb away from the body.
- Muscles fall in to 4 different categories
- Contractions.
- Isotonic contractions - these can be concentric or eccentric.
- Concentric - when thee muscle shortens eg. the bicep in the arms.
- Eccentric - when the muscle gradually lengthens and returns to its normal length and shape.
- Isometric contractions - no actual movement of either limb or the joint because the muscles are working to keep the joint stable.
- Isotonic contractions - these can be concentric or eccentric.
- Muscles and movement - this allows to move body parts, stabilize joints when movement is happening and protects you vital organs.
