Study Notes
Amoeboid Movement
- Macrophages and leucocytes move using amoeboid movement, which involves the change in shape of the cell.
- Amoeboid movement is characterized by the formation of temporary cytoplasmic projections called pseudopodia, which allows the cell to move along a surface.
- Pseudopodia are formed due to the flow of cytoplasm within the cell, driven by the interaction of cytoskeletal components like actin and myosin.
Ciliary Movement
- Ciliary movement occurs in the trachea, bronchi, and other parts of the respiratory system, as well as in the fallopian tubes, and the ventricles of the brain.
- The coordinated movement of cilia in the trachea helps to move mucus and trapped particles upwards, away from the lungs, preventing infection.
- The beating of cilia creates a current, which sweeps the mucus and trapped particles towards the throat where it can be swallowed or coughed out.
Required for Movement
- Locomotion and other movements by human beings and most multicellular organisms require a well-developed muscular system.
- The muscular system works in conjunction with the skeletal system to allow for movement.
- The nervous system controls the muscles, enabling coordinated and purposeful movement
