What to Focus On
- Amoeboid movement is shown by macrophages and leucocytes.
- Ciliary movement helps in dust removal from the trachea.
- Muscular movement produces body movements and locomotion.
- Muscles contribute about 40-50% of adult body weight.
- Muscles are excitable, contractile, extensible, and elastic.
- Skeletal muscle is striated and voluntary.
- Sarcolemma is the plasma membrane of a muscle fibre.
- Sarcoplasmic reticulum stores calcium ions.
- Actin forms the I band and myosin forms the A band.
Common Mistakes to Avoid
All movement is locomotion.
Cardiac muscle is voluntary because it is striated.
Troponin runs along actin, so tropomyosin must be the one that covers the active sites.
Memory Tips

Three main types of movement in human body cells
