Nerve Tissue

Nerve Tissue Tissue nerve form system nerve. System nerve works ensure sensitivity animal to influence the environment. With thereby, system nerve capable respond influence Which happen from the environment. In side That, system nerve capable control movement muscle, secretion gland, And role big on Act in demand instinct. Tissue nerve This consists on cells nerve Which called neurons . a. Nerve cell structure (Neurons) cell Which consists on mitochondria, body golgi, lysosomes, And body niessl . Body niessl This Actually is reticulum endoplasm Whichrole important For synthesis proteins. 2) Dendrites Dendrites are extensions of the cytoplasm of the nerve cell body. Usually experience branching in amount Which Enough Lots. Dendrites together with perikarion form area main For accept stimulation, Then bring it to body cell nerve. So, function main Dendrites is carries stimuli to the nerve cell body. At the ends of each Dendritic branches have very fine bumps which are useful for paste himself to nerve other. 3) Neurite (axon) Picture 1. Nerve cell structure Cell nerve or neurons is units functional on system nerve. Neurons Which found in the body in various forms depending on the location existence And its function. Cytoplasm cell neurons contain organelles between other body golgi, mitochondria, And reticulum endoplasm. For continuity his life, neurons get supply food through neuroglia Which there is in surroundings. Neurons own body cell, dendrites, And neurite (axon). Following will outlinedeach part neurons the. 1) Body cell The cell body is the main part of a nerve cell that contains the nucleus, cytoplasm, membrane cell, And contain One or more branching cell shaped _ slim, very long, And branching. Branching body cell nerve This consists on Dendrites And axon. In in cytoplasm body cell nerve there is organelle Neurite or axon is extension cytoplasm body cell nerve. Neurite Also experience branching single Which very long like case edges Dendrites. On edges neurites there is bumps Which very fine For paste himself on cell nerve other. Neurite works For bring stimulation leave body cell nerve going to cell nerve another or tissue, like gland And muscle. Axon formed by three part, that is neurilemma (cell schwan), sheath myelin, And node ranvier . Neurilemmaor Schwan cells are the supports for axons in several animals vertebrates. Sheath myelin is sheath fat Which there is in around axon. Sheath myelin This consists on membrane cell Which widespread from cell schwan, but No all axon shrouded myelin, for example on place meeting between One sheath from One cell Schwan And sheath next. Nodes ranvier works For speed up the way impulse nerve. Besides myelin, axon Also own protector Which arranged on cells Schwan. Cells here it is Which load sheath myelin membrane cell Schwan outermost, called neurilemma. Neurilemmaonly there is on system nerve edge. a. Classification Neurons (Cell Nerve) Based on structure or shape, neurons shared become three, that is neurons unipolar, bipolar, And multipolar. Unipolar neurons are characterized by own One branch axon Which originate from body cell. On Neurons bipolar ter- can One Dendrites Which branching And One axon, whereas neurons multipolar own a number Dendrites And One axon. Third structure each neurons. Based on method neurons move- right excitatory And place existence neuronsshared become three type, that is neurons taste, neurons motorbike , And neurons association . 2) Neurons association intermediate/interneuron) (neurons Neurons association continue impulse nerve from neurons Which One to neurons other. Neurons association This form something eye chain, there is on system nerve center. Neurons This will experience stimulation by impulse Which originate from neurons sensory or from neurons association other. Neurons association almost there is in all over trajectory coordination nerve. Can You imagine How many amount neuronsassociation This on system nerve center? 3) Neurons motor (neurons mover) Neurons motorcycle works as carrier impulse to effector, that is muscle And gland. Generally neurons motorcycle accept impulse from neurons association. However, sometimes impulse moved in a way direct from neurons taste to neurons mover. Picture 2. Various form structure neurons. (a) unipolar, (b) pseudopolar, (c) bipolar, (d) multipolar. 1) Neurons Taste (Neurons Afferents/Neurons Sensory) Neurons This works For accept impulse from receptor, like part eye Which react to light And continue impulse That to neurons other. Generally neurons taste convey stimulation from organs recipient excitatory (receptor) For Then convey it to system nerve center (brain And marrow bone back) . Bodies cell neurons sensory This generally group, called ganglia And neurons This continues until to rope spinal. Axon neurons sensory bring impulse excitatory going to tissue nerve center. Picture 3. Direction excitatory nerve.
