Locomotion and Movement: - NEET PDF Download

Movement is when the living organism moves a body part or parts to bring without a change in the position of the organisms. Locomotion is when the movement of a part of the body leads to change in the position and location of the organism. Both of these are brought about by the joint efforts of the skeletal and muscular systems. Movement is seen in both vertebrates and invertebrates.


Types of Movements

When we talk about locomotion and movement, there are three types of movements:


Amoeboid movement is brought about by pseudopodia which are appendages which moves with movement of protoplasm within a cell.


Ciliary movement is brought about by appendages called as cilia which hair-like extensions of the epithelium. Both these kinds of movements are seen with cells of the lymphatic system.


Muscular movement 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 types of muscles, and joints.

FAQs on Locomotion and Movement: - NEET

1. What is locomotion?
Ans. Locomotion refers to the ability of an organism to move from one place to another. It involves the coordination of various body parts and systems, such as muscles, bones, and nerves, to generate movement.
2. How does locomotion differ from movement?
Ans. Locomotion specifically refers to the act of moving from one place to another, while movement is a broader term that encompasses any change in position or posture. Locomotion usually involves purposeful and directed movement, while movement can be involuntary or accidental.
3. What are the different types of locomotion observed in animals?
Ans. Animals exhibit various types of locomotion, including walking, running, swimming, flying, crawling, hopping, and slithering. These types of locomotion are adapted to suit the specific needs and environments of different animal species.
4. How do animals achieve locomotion?
Ans. Animals achieve locomotion through the coordinated action of their muscles, skeletal system, and nervous system. Muscles contract and relax to generate force, while the skeletal system provides a framework for support and leverage. The nervous system controls and coordinates the movement by sending signals to the muscles.
5. Can locomotion be impaired or affected by certain conditions or diseases?
Ans. Yes, locomotion can be impaired or affected by various conditions or diseases. Examples include paralysis, muscle weakness, joint problems, neurological disorders, and injuries. These conditions can hinder the normal functioning of the muscles, bones, or nervous system, leading to difficulties in movement or limitations in locomotion.
