Document Summary
5th march 2018: lecture 3 connective tissue. Resident (fixed) and wondering (transient) cell population (migrated from. (cid:498)blast(cid:499) (immature) and (cid:498)cyte(cid:499) (mature) blood as a result of specific stimuli) Active fibroblast (immature): bigger, abundant and branched cytoplasm processes, rich in rough endoplasmic reticulum, golgi apparatus and oval nucleus) Quiescent fibrocyte (inactive/ mature): smaller, spindle shaped, elongated nucleus. Synthesise collagen, elastic and reticular fibres and extracellular material. Specialised for fat storage, energy and insulation; involved in the synthesis of hormone and growth factors. Cytoplasm with flattened nucleus forms a very narrow rim around a large central lipid droplet: macrophage: Fixed (stays in one spot) and wondering (moves around) Can be found in the kidney: mast cells: Develop in bone marrow (blast immature) differentiate in connective tissue (cyte mature) (histamine and heparin blood thinner) and kills. Function: inflammatory and allergic response bacteria: extracellular matrix, fibres: Consists of water, complex carbs and glycoproteins: functions:
