GENERAL HISTOLOGY

Detailed explanation-1: -Cilia and flagella. Cilia and flagella are motile, hair-like projections of the cell surface. They create currents in the surrounding fluid or movements of the cell to which they are attached, or both.

Detailed explanation-2: -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. If a cell has any flagella, it usually has one or just a few.

Detailed explanation-3: -Cilia are short, numerous, hair-like projections from the plasma membrane. They move in a “wave” motion. The cilia move the cell by beating rhythmically. Flagella function to move the cell by one long projection that moves in a whip-like motion.

Detailed explanation-4: -The cilium is a microtubule-based cellular projection that can be motile, sensory or both. Motile cilia and flagella beat to propel the cell or move the surrounding milieu.
