Types of Movement in the Human Body MCQ - Practice Questions with Answers

• Cells of the human body exhibit three main types of movements as:
  • amoeboid 
  • ciliary 
  • muscular

Amoeboid Movement:

• Some specialised cells in our body like macrophages and leukocytes in blood exhibit amoeboid movement. 
• It is affected by pseudopodia formed by the streaming of protoplasm (as in Amoeba).
• Cytoskeletal elements like microfilaments are also involved in the amoeboid movement.
• Circulating WBCs have four characteristics movements:
  • Diapedesis or Migration: They can migrate out.
  • Amoeboid Movement: They move through the endothelium and into the peripheral tissues
  • Positive chemotaxis: They are attracted by specific chemical
  • Phagocytosis: They have the ability to engulf the pathogen, cell debris and other material

Ciliary Movement:

• It occurs in most of our internal tubular organs which are lined by ciliated epithelium. 
• The coordinated movements of cilia in the trachea help us in removing dust particles and some of the foreign substances inhaled along with the atmospheric air. 
• Passage of ova through the female reproductive tract is also facilitated by the ciliary movement.

Muscular Movement:

• Movement of our limbs, jaws, tongue, etc, require muscular movement.
• The contractile property of muscles is effectively used for locomotion and other movements by human beings and the majority of multicellular organisms. 
• Locomotion requires a perfect coordinated activity of muscular, skeletal and neural systems.

Flagellar movements:

• This type of movement occurs in protozoans like Trypanosoma, Euglena etc. along with sponges.
• In sponges, flagella of choanocyte cells maintain a regular current of water through the canal system.
• In the case of human beings, the sperm swim in water or in the female genital tract with the help of its flagellar movements only
