Cytoskeletti

Cytoskeleton, often referred to as the "skeleton" of the cell, is a complex network of protein filaments and tubules that provides structural support, facilitates movement, and aids in cell division. It is composed of three main types of filaments: microtubules, microfilaments, and intermediate filaments. Microtubules are hollow tubes made of tubulin proteins, which are crucial for cell division, intracellular transport, and maintaining cell shape. Microfilaments, also known as actin filaments, are composed of actin proteins and play a role in cell movement, contraction, and adhesion. Intermediate filaments are made of various proteins and provide mechanical strength and stability to the cell. The cytoskeleton is dynamic and constantly remodeled, allowing cells to adapt to their environment and perform various functions. It is essential for processes such as cell migration, division, and signaling, and its disruption can lead to diseases like cancer and neurodegenerative disorders. The cytoskeleton is a vital component of the cell, contributing to its structure, function, and overall health.
