Document Summary
200 kinds of cells in the human body egg) Squamous - thin, flat, scaly shape, bulge where nucleus is (sunny side up. Cuboidal- square, equal in height and width. Columnar - taller than wide (stomach and intestines) Spheroidal- round/oval (egg cells and white blood cells) Fusiform- elongated, thick middle and tapered ends (muscle cells) Cytoplasm - liquid between nucleus and surface membrane (jelly) Contains: cytoskeleton, proteins, filaments and tubules, organelles, inclusions. Plasma (cell) membrane - can differ from one region to another. Cytosol/ intracellular fluid (ifc)- cytoskeleton, organelles, and inclusions embedded. Extracellular fluid (ecf)/ tissue (interstital) fluid- body fluids not contained in the cells. 3d images w high magnification and resolution. It cannot support itself: what is the difference between cytoplasm and cytosol, cytoplasm- gelatinous mixture of chemicals and vaguely define particles i. Between nucleus and surface membrane: cytosol- clear gel, where cytoskeleton, organelles, and inclusions are embedded, define intracellular fluid (ifc) and extracellular fluid (efc) a.
