    Microtubules are essential components of the eukaryotic cytoskeleton, playing crucial roles in various cellular processes. In the human body, their functions include: Structural support: Cell shape: Microtubules help maintain cell shape and rigidity, providing a framework for the cell. Organelle positioning: They are involved in positioning organelles within the cell, ensuring proper cellular organization. Cell division: Mitotic spindle formation: During cell division, microtubules assemble into the mitotic spindle, which separates chromosomes between daughter cells. Chromosome segregation: Microtubules attach to chromosomes and pull them apart to opposite poles of the cell. Intracellular transport: Vesicle transport: Microtubules serve as tracks for motor proteins like kinesin and dynein, which transport vesicles and organelles throughout the cell. Intracellular trafficking: They facilitate the movement of materials such as proteins and mRNA within the cell. Cilia and flagella: Movement: Microtubules form the core of cilia and flagella, which are hair-like structures that enable cell movement. Sensory functions: Cilia and flagella are also involved in sensory functions, such as detecting changes in the environment. Other functions: Cell signaling: Microtubules are involved in cell signaling pathways, regulating various cellular processes. Neuronal function: In neurons, microtubules play a role in axonal transport and synaptic transmission.See more
