Document Summary

Introduction to anatomy: study of internal and external body structures, gross anatomy, microanatomy. Study of structures large enough to be visible to the eye. Study of structures that require a microscope: studies internal structures of cells. Ions: elements that are electrically neutral, elements that are not electrically neutral, anion = negative, cation = positive. Materials: store energy, cell structures, protect organs, build cell. Membranes: store energy, structural materials, enzymes, proteins, nucleic acids, atp (ribose sugar) Molecules, acids and bases can be organic or inorganic. Types of lipids: glycerides (composed of glycerol and fatty acids, phospholipids, cholesterol, steroids (produced from cholesterol) Function of dna: cellular reproduction, instructions for building, template for protein synthesis. Membrane proteins can be peripheral, integral or transmembrane. Membrane carbohydrates: extended into the ecf, bound to proteins or lipids, used for cell recognition or anchoring cells together. Types of cytoskeleton: microfilaments (actin, intermediate filament. Ex. keratin filaments in epithelial tissue: microtubules (tubulin)
