(a) Macrophages and leucocytes in blood exhibit amoeboid movement. Cytoskeletal elements like microfilaments are also involved in amoeboid movement.

(b) Ciliary Movement These types of movements occurs mostly in the internal organs, which are lined by the ciliated epithelium. e.g., cilia in trachea helps in removing dust particle and foreign substances inhaled along with atmospheric air.

Passage of ova through the female reproductive tract is also facilitated by the ciliary movement. This is due to the presence of ciliated epithelium in the Fallopian tube.

Locomotion requires a prefect coordinated activity of muscular, skeletal and neural systems.

There parts belongs to the muscle fibre, which is lined by the plasma membrane called sarcolemma. Muscle fibre is a syncitium because sarcoplasm (the cytoplasm) of muscle fibre contains number of nuclei and sarcoplasmic reticulum is the endoplasmic reticulum of the muscle fibre and is the store house of calcium ions.

Each middle ear contains three tiny bones, named, i.e., malleus, incus and stapes which are collectively called as ear ossicles.
