Document Summary

Muscles bundle of muscle fibres multinucleated muscle cell myofibril . Cells have the ability to import and export cargo. Cells can migrate into wounds not only bacteria that can move around, but cells within our own body can migrate. Movement of cells is for healthy physiology/function of cell. Also prevalent in disease, metastasizing cells crawling into the body, punching through epithelial cells. Cell constructs a cytoskeleton that shapes it just like our skeleton shapes us. They make small building blocks that are able to self-assemble. The cytoskeleton plays a key role in cell physiology and metabolism. Play role in structure of cells because stiffer. Longer protofilament structures (13 of them form hollow tube) Formation of nuclear lamina - gives nucleus mechanical structure. Resistant to compression; - large, rigid, hollow tubes. like. 2 plexi-glass, will not buckle under a lot of compression, resistant to compression. But flexible; - if you pull from both ends, won"t break;
