Types of Movements
There are three types of movements. They are
- Amoeboid movement
- Ciliary movement
- Muscular movement
1. Amoeboid movement:
The movement that is brought about by structures known as pseudopodia is known as amoeboid movement.
Example:
Amoeba, cellular slime moulds, human cells such as Kupffer cells of liver, monocytes, neutrophils, macrophages, and cancerous cells.
2. Ciliary movement:
The hair-like extensions of the epithelium are known as cilia.
The movement that is brought about by these types of appendages is known as the ciliary movement.
Ciliary movement in Paramecium:
Example:
Paramecium, in the respiratory tract of humans, lymphatic system of humans, fallopian tubes of female mammals.
3. Muscular movement:
It is the most complex movement brought about by the musculoskeletal system. This movement is seen only in higher vertebrates.
To know more about this movement, the structures that form the musculoskeletal system are to be studied in detail. This will be discussed in the following theories.
Movements in the human body
In humans, some of their parts can be moved in different directions, and some of them can be moved only in one direction. The human body is made up of a framework of bonescalled a skeleton. It is the structure that helps in the movement of the body. Some of the movements in the body parts of humans are as follows:
- Movement of the muscles of the heart
- Movement of the eyelids
- Movements of the teeth and jaw
- Movements of the arms and legs
- Movements of the head
- Movements of the neck
In some of the organs, movements occur due to the combined action of bones and muscles. In these type of situations, movements are possible at points where two or more bones meet.
