 When we think of the word movement, we often tend to think of something we do with our arms or, let's say, walking. But this is only one kind of movement that the human body is capable of. Muscular movement. What are the other kinds of movement? That's what we will explore in this video. So, first off, let's look at amoeboid movement. So, just as the name suggests, it is the kind of movement that takes place in amoeba. So, what an amoeba does is it extends its cell membrane and then the cytoplasm follows and that is how the cell moves forward. So, this is called amoeboid movement and which human cells exhibit that movement? WBCs like neutrophils and macrophages. Next up is ciliary movement, ciliary movement. In this type of movement, as you can see, these hair-like structures, they move. Their movement is like sweeping by a broom. So, just like a broom sweeps away dirt, these cilia too sweep away something or the other. For example, they are found in our upper respiratory tract. So, the cells lining the upper respiratory tract, they have cilia and let's say there is a dust particle somewhere in the upper respiratory tract, let's say in your nose or your throat and what the cilia do is that they sweep them away towards the outside so that the dust particles don't go and settle in the lungs because that will cause different problems. So, the other place where cilia are found is the oviduct or the fallopian tube. The egg that is released every month in the oviduct, it moves along the oviduct and wastes for the sperm. The movement of the egg is caused by the sweeping action of the cilia. The next type of movement is flagellar movement and this type of movement is found in sperm. So this is the flagellar movement and the flagellum is very similar to a cilia in the sense that it's a very thin hair-like structure but the difference is in a cell there is only one or a few flagella whereas there are numerous cilia. So in a sperm there is only one flagellum which moves with a whip-like motion and propels the sperm forward and then of course we have muscular movement which is very widespread in our body and we are very familiar with it because we use this kind of movement to move our hands, our feet, our arms, our legs, our tongue, you name it all the kinds of voluntary movement and even involuntary movement is a type of muscular movement. So by involuntary movement I mean the beating of the heart or the contractions of the stomach when you have food inside it. All this is caused by muscular movement. So in summary we have four types of movement in the human body. The amoeboid movement which is exhibited by neutrophils and macrophages, types of WBCs. Then there is the cilia movement which is present in the cells lining the upper respiratory tract and the oviduct. Then there is the flagellar movement which is exhibited by the sperm and then there is muscular movement, hands, feet, heart, muscles, all of this is muscular movement.
