7. What are the different types of movements exhibited by the cells of the human body?
The different types of movements exhibited by the cells of the human body are as follows:
1. Amoeboid movement - The leukocytes present in the blood show amoeboid movement. During tissue damage, these blood cells move in an amoeboid manner (by forming temporary pseudopodia) from the circulatory system towards the site of injury to initiate an immune response.
2. Ciliary movement- The reproductive cells such as sperms and ova show ciliary movement. The passage of ova through the fallopian tube towards the uterus is facilitated by this movement.
3. Muscular movement- The muscle cells of the human body show muscular movement. These contract and relax to bring about the movement. E.g. Movements of limbs, tongue and jaws are examples of muscular movements.
