Spindle (anatomy)

In anatomy, the spindle refers to a specialized cell structure during cell division, particularly mitosis. It is a dynamic, thread-like formation made of microtubules that stretches across the cell’s center. Its main function is to organize and evenly split chromosomes between two daughter cells. The spindle attaches to chromosomes via kinetochores and pulls sister chromatids apart, ensuring each new cell receives the correct genetic material. This process is crucial for growth, tissue repair, and maintenance in living organisms. The spindle’s precise operation is essential for healthy cell division and genetic stability.
