ANAPHY TERMS

• Astrocryte regulates ion
• Microglial cell defends the neurons against materials.
• Ependymal cell lined cavities
• Oligodendrocyte wraps and insulates axon
• Sattelite cell surrounds the neurons
• Schwaan cell surrounds and insulates axon
• Nervous system group of tissue composed of high specialized cells
• Nervous tissue densely pack of cell
• Glial Cell

  • surrounds and protects gets nutrition
  • for insulation (regulation of temperature)
  • helps for the signal transmission
  • jacket of neuron
• Neurons

  • response to stimuli
  • active conducting elements
• PERIKARYON

  • consist of a cell body
  • contain single nucleus
  • process transmitting impulse to and from the cells body
• Neuroglia supporting elements
• Dendrites Group of short, unsheated processes arrange like branches of tree that transmit
• Axon Single, elongated sheated process conducting impulses away from the cell body
• Somatic efferent innervating somatic structures (skeletal muscles and skin) can control
• Visceral Efferent involuntary structures ( smooth muscles, cardiac muscles and glands) cannot control
• synapse connection between neurons
• cell membrane inside (negative), outside (positive)
• Action Potential sudden changes in the eletric charge in the membrane
• Myelin Sheath - insulating material covering axons in central and peripheral nervous system, the thicker, the faster the passage of nerve impulse will be.
