Cells of the human body exhibit three main types of movements, namely, amoeboid, ciliary and muscular.Some specialised cells in our body like macrophages and leucocytes in blood exhibit amoeboid movement. It is effected by pseudopodia formed by the streaming of protoplasm.
Ciliary movement occurs in most of our internal tubular organs which are lined by ciliated epithelium. The movement of cilia in the trachea help in removing dust particles and some of the foreign substances. Passage of ova through the female reproductive tract is also facilitated by the ciliary movement. Movement of our limbs, jaws, tongue etc. requires muscular movement. The contractile property of muscles are effectively used for locomotion and other movements by human beings.
