fourthyearmed Senior Member 5+ Year Member. Yes, 3rd year is long, hard, a lot of work, and has tests but I still enjoyed it so much more than the HELL that was 1st and 2nd years. 3rd year involves interaction not just with patients but with other people in the medical field besides your classmates.
The mitotic spindle is the macromolecular machine that segregates chromosomes to two daughter cells during mitosis. The major structural elements of the spindle are microtubule polymers, whose intrinsic polarity and dynamic properties are critical for bipolar spindle organization and function.he mitotic spindle is the macromolecular machine that segregates chromosomes to two daughter cells during mitosis.

During mitosis the mitotic spindle, a football-shaped structure of microtubules, guides the separation of two sets of daughter chromosomes. Spindle microtubules grow from two centrosomes, clouds of cytoplasmic material that in animal cells contain centrioles.
