Back to the Basics: Anatomy, physiology, and diseases

I was having a really difficult time trying to figure out a way to present this. The nucleus is complicated. It has a separate membrane, called the nuclear envelope, and has nuclear pores which move ribosomes into and out of the nucleolus, etc., etc... along with other structures that may or may not be important to you. From my experience, what its function is is more important than the finite details of its structure. The nucleus is the castle of the cell. This is the place where all the decisions are made. Deoxyribonucleic acid (DNA) or the genes of the cell are in that castle. This DNA tells the cell what it will be, the function of its parts, and when and how often it will divide. "You will be a skin cell and you will divide in 2 weeks to make more skin cells. The ruler has spoken!"  Some cells, such as muscle cells have to produce a lot of ATP (cell energy), where other cells do not. This is also determined by the nucleus. The head honchos determine what work needs to be...
