Name the cells/tissues in human body which
(a) exhibit amoeboid movement
(b) exhibit ciliary movement
Explanation
(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.
