Forming Tissue in Animals

Forming Tissue in Animals Like has mentioned previously, network formed from a number of cell results process differentiation, Then experience process specialization. Process differentiation, that is process multiplication cell through function reproduction cell, whereas process specialization is process carry on from differentiation as process change form And function. Cells Which form And its function The same furthermore will group become One unity form network . By general body animal nor organism other arranged on four type network base, between other: 1) Network epithelium located on surface body, works as closing surface outside body And barrier organ body Which shaped channel orcavity. 2) Network tie, is network Which own function For tie orsupport parts body. 3) Network muscle, works For move all over part member body. 4) Network nerve, works For accept And respond exists excitatory as well as convey excitatory (impulse) to center nerve as well as to part body Which other. 1. Epithelium Tissue Network epithelium (ep surface), that is network Which cover And limit surface part body Which form organ, cavity, And channel, Good Which located in in nor in outside body. Network epithelium or epithelium own function Which different in accordance located at in body. Epithelium flat works For protect And bandage network Which located in underneath, for example epithelium flat Which there is in surface skin. Temporary That, epithelium cylindrical And cube works as membrane permeable Which become Then cross substance. Example epithelium cylindrical on channel intestines fine For absorb sari food, or epithelium on nephron Which Lots passed by urine primary. Epithelium gland works as producer sap Which can utilized by body. In side That, There is also epithelium Which works For accept excitatory,called epithelium recipient. Epithelium This Lots there is in around senses, like epithelium sensory in around neurons And retina eye. Network epithelium can form membrane And can also form gland. Network epithelium separated from network tie in underneath by membrane thin Which called membrane base (lamina basalt) . Membrane base This arranged on fibers collagen Which attached on something matrix. Membrane base works For support network epithelium. Based on location on part body, network epithelium divided become epidermis , endothelium, And mesothelium . Epidermis is network epithelium Which located on parts _ body outermost, works as protector most outside. Endothelium is epithelial tissue Which bandage organs in body. Network mesothelium is network epithelium Which coating parts body Which shaped cavity. From arrangement cells Which arrange it network epithelium with easy can recognized. Characteristic network epithelium, that is the cells arranged very meeting so that almost No there is room in between the cells . Type network epithelium usually shared based on form cell And amount the arrangement in layer. By general, based on cells Which put it together, network epithelium differentiated become three, that is epithelium flat or flat (squamous), epithelium cube (cuboid), And epithelium stem (cylindrical) . with boundaries Which No regular. Based on the arrangement, Which including epithelium group This is endothelium Which coating vessels blood, vessels lymph, And mesothelium lining the serous cavities (pleura, pericardium, etc peritoneum) . Example epithelium layer flat Which other there is on alveoli lungs, ear part middle And in. 2) Cells epithelium can differentiated also based on amount layer cell Which arrange it that is epithelium simple (one layer) And epithelium layered (complex). a. Epithelium One layer (Simple) Characteristic base from epithelium This, that is only arranged on One layer cell just. Epithelium layer shared become three, that is epithelium flat (flat) layer, epithelium cube layer, And epithelium cylindrical layer. 1) Epithelium flat layer Epithelium flat layer consists on cells Which very flat,thin, own the edge No regular, And each other close together form something sheet Which perfect. If seen from surface, epithelium This looks like floortile floor, but Epithelium cube layer Epithelium This called thereby Because on incision upright straight to surface, every cells looks like box or cube. From the surface the cells are visible shaped polygonal. Epithelium cube simple there is on Lots glands , on gland secretion, nor on channel output. 1) Epithelium cylindrical layer Epithelium cylindrical layer There is Which the cells own cilia, There is also Which without cilia. Epithelium cylindrical layer Which without cilia, If seen from surface, looks almost similar with epithelium cube layer. On piece upright straight will looks consists on cells Which tall with core in a row at the same height and located closer to basal (base) surface rather than to the apical surface (end). Epithelium type This usually relate withretion or absorption. Lots there is coating part big channel digestion like stomach And intestines fine or on channel expenditure Which produce Lots gland. Epithelium cylindrical layer Which ciliated seen surface free closed cilia. Epithelium type This coating womb (uterus), reed womb (tube uterine), on channel testicles, And bronchi small. b. Epithelium Layered Epithelium This arranged by a number of ply cell so that called epithelium layered. Function epithelium layered generally as protector. Function as protector more possible For epithelium layered Because arranged by a number of ply cell, so that more stand For withhold disturbance from outside compared to with epitheliumlayer Which only arranged from One layer cell. By Because That, epithelium layered there is on places Which Lots caught friction And scratches. However Because the layer Which thick, membrane epithelium layered No earmarked for absorption substance. Based on form layer surface free, epithelium layered shared become four type, that is epithelium layered flat (flat), epithelium layered cube, epithelium layered cylindrical, And epithelium transitional . Fourth type epithelium layered more he explained will discussed as following.
