MICROANATOMY

Detailed explanation-1: -Flagella (singular, flagellum) are long, hair-like structures that extend from the cell surface and are used to move an entire cell, such as a sperm.

Detailed explanation-2: -Cytoskeletal filaments provide the basis for cell movement. For instance, cilia and (eukaryotic) flagella move as a result of microtubules sliding along each other.

Detailed explanation-3: -Microfilaments, also called actin filaments, as they consist of two intertwined strands of a globular protein known as actin. They are the polymers of the protein actin and are smallest filaments of the cytoskeleton. They have a vital role in cell movements, cell division, and muscle contraction.
