Document Summary

Things i should have known for midterm 1. Inclusions: chemical substances, could be present depending on cell type (ex. Endoplasmic reticulum: er: interconnected tubes and parallel membranes surrounded by fluid-filled cavities (cisterns, rough er: studded with ribosomes that assemble proteins, and then enclose them in vesicles that bring them to the golgi apparatus. In smooth muscle and skeletal muscle, it contains the calcium ions: most body cells don"t contain a lot of smooth er. Endomembrane system: system of organelles (all described above) that work together to produce, degrade, store and export biological molecules and degrade potential harmful substances, nuclear envelope is directly connected to ers. Cytoskeleton: microfilaments: semi-flexible strands of actin protein, form terminal webs to strengthen. Woven units of tetramer: attached to desmosomes, resist pulling forces on the cell, name varies for the type of cell (keratin filaments or neurofilaments)
