Types of Movements
When we talk about locomotion and movement, there are three types of movements.
It is brought about by pseudopodia which are appendages which move with movement of protoplasm within a cell.
This movement is brought about by appendages called as cilia which are the hair-like extensions of the epithelium. Both these kinds of movements are seen with cells of the lymphatic system.
It is a more complex movement which is brought about by the musculoskeletal system. This type of movement is seen in the higher vertebrates.
To understand more about the movements brought about by the musculoskeletal system, we need to understand the joints, skeleton and types of muscles.
