MICROANATOMY

Detailed explanation-1: -The cytoskeleton is a structure that helps cells maintain their shape and internal organization, and it also provides mechanical support that enables cells to carry out essential functions like division and movement.

Detailed explanation-2: -Long fiber-like proteins are found in connective tissue in the extracellular matrix forming the basement membrane that epithelial tissue connects to, but also found inside the cell to strengthen it such as in blood vessels.

Detailed explanation-3: -Protein Fibers Microtubules are hollow rods functioning primarily to help support and shape the cell and as “routes” along which organelles can move. Microtubules are typically found in all eukaryotic cells. They vary in length and measure about 25 nm (nanometers) in diameter.
