Answer:
Types of Movement in Living Organism:
There are three main types of movements shown by the cells of the human body, viz., amoeboid, ciliary and muscular. But flagellar movement is also found.
1. Amoeboid (= Pseudopodial) Movement:
This type of movement is found in leucocytes (phagocytes and macrophages of the human lymphatic system).
2. Ciliary Movement:
Cilia of the upper respiratory tract of humans keep the invading microbes and dust particles out. Whereas, the cilia of the Fallopian tubes (oviducts) and vasa efferentia of human females and males, transport ova and spermatozoa, respectively.
3. Muscular Movement:
This basic mechanism is used in the majority of vertebrates, including humans. The universal property of this mechanism is to exert a force by alternate contraction and relaxation. Movement of our limbs, jaws, tongue, etc. require muscular movement.
4. Flagellar Movement:
ADVERTISEMENTS:
Human sperms (typical example of flagellated cells) exhibit the flagellar movement. The flagellum is the propulsion equipment for the movement of sperm towards the ovum. This propulsion is brought about by the whip like movement of the tail and the middle piece of the sperm.
