Explain
the benefits and functions of the nervous system
Nervous system is divided into two main sections:
2 - PNS Peripheral Nervous System.
The building unit of the nervous system is the neuron (nerve cell) Neurone, and the human nervous system consists of two basic types of cells, are glial cells Glial Cells and Neurons Neurons.
And neuron consists of body Cell Body and axis Axon, and the cell body contains the nucleus of the cell and highlights of its surface Ngsnat or ramifications of the outside have to do in the reception or transfer electrical signals, and receives body neuron electrical signals (nerve) of neurons other by dendrite Dendrites of the body of neuron another or from the axis of neuron another by fasteners Synapsis, and clamp is a space at the confluence Ghosn neuron or axis neuron with body cell neuron last to transfer electrical signals through chemicals called neurotransmitters Neurotransmitters and are numerous and including Alosetayl Colin Acetylcholine and adrenaline Adrenaline and noradrenaline Noradrenaline.
Axis neuron Axon is a stretch out from the cell body and transmits electrical signals from neuron. And axis envelope from abroad plates myelin (myelin) Myelin Sheaths and is a dielectric material axis and necessary for the transfer of electrical signals which, in the central nervous system glia few dendrite Oligodendrocytes are responsible for producing myelin, whereas in the peripheral nervous system Fajlaya Schwann Schwann Cells is responsible for the production of myelin (myelin).
In the nervous system collect the bodies of the neurons in the totals, and these totals in the central nervous system called the nucleus Nucleus or node Ganglion, while in the peripheral nervous system are called these totals, a contract (a single "node") Ganglion.
As well as gathering hubs neurons with each other to be nerves Nerves, nerves are divided in terms of location of the node into two types:
In the nervous system, nerves (axes objects neurons) before node intertwined with objects neurons that arise from nerves after node during clamps in the contract for the transfer of electrical signals. We can say or likened decade stations train to transfer load (electrical signals nerve) from train the last to be finally delivered to the desired member.
Glial cells Glial Cells are support cells for neurons in the nervous system and is not involved in the transmission of nerve signals (electrical). And the number of glial cells nearly ten times the number of neurons in the nervous system, but as glial cell size equal tenth the size of the neuron blocs same understanding of the space (mass) in the nervous system. Label glial cells derived from the Latin word "Gallia" (Glia), which means glutinous or glue or gum to popular belief previously that its core business is connectivity between neurons (such as cement in construction).
