Ch 17 - Locomotion and Movement11th Biology
Movement vs. Locomotion
What is the fundamental biological distinction between 'movement' and 'locomotion', and how do they logically relate to each other?
What is the fundamental biological distinction between 'movement' and 'locomotion', and how do they logically relate to each other?
- Movement: Any change in posture or position of body parts (e.g., streaming of protoplasm, moving jaws, beating of cilia).
- Locomotion: A strictly voluntary movement that results in a change of place or location (e.g., walking, swimming, flying).
- Relationship: All locomotions are movements, but not all movements are locomotions.

Amoeboid Movement
Which specific human cells exhibit amoeboid movement, and what cytoskeletal elements are involved in executing it?
Which specific human cells exhibit amoeboid movement, and what cytoskeletal elements are involved in executing it?
- Exhibiting Cells: Specialised immune cells like macrophages and leucocytes in the blood.
- Mechanism: Effected by the formation of pseudopodia via the streaming of protoplasm (similar to Amoeba).
- Cytoskeletal Elements: Microfilaments strictly facilitate this type of cellular movement.

Ciliary Movement
Where does ciliary movement primarily occur in the human body, and what are its two major physiological functions?
Where does ciliary movement primarily occur in the human body, and what are its two major physiological functions?
- Location: Occurs in most internal tubular organs lined by ciliated epithelium.
- Function 1 (Trachea): The coordinated beating helps remove dust particles and foreign substances from inhaled air.
- Function 2 (Reproductive Tract): Facilitates the passage of ova through the female reproductive tract.
