Nervous System Set 2 hold online at quizlet. com/_6rnj1 2. What are the classifications of neurons? 3. What are the four types of neuroglia in systema nervosum centrale? 4. What are the ii types of fast axoneal station? 5. What are the two types of neuroglia in PNS? 7. What do brain tumors arise from? 8. What do schawnn cells do in PNS? 9. What does the neuroglia or glial cells do? 10. What guides microtubules along axon? 11. What is anaxonic neuron? 12. What is anterograde transport? 13. What is astrocytes? 14. What is axonal transport or axoplasmic pass? 1.What are schwann cells? envelope impudence fibers in PNS. produce a myelinee sheath multipolar, bipolar, unipolar and anaxonic oligodendrocytes, ependyal cells, microglia and astocytes Fast anterograde and fast retrograde. Occurs at a rate of 20 to 400 mm/day Schwann cells and satellite cells. pack of rapidly dividing cells. meninges (protective membrane of CNS), Metastasis from nonneuronal tumors in different organs. Often glial cells that are mitotically active throughout life spiral repeatedly close to a single nerve fiber. support and protect the neurons.Prevents neurons from touching eachother and gives precision to conductivity pathways motor proteins (kinesin and dynein) carry materials on their backs while they crawl along microtubules many dendrites but no axon. Help in visual processes campaign away from the soma down the axon maintain structure. nerve proceeds factors secreted by astrocytes promote neuron growth and synapse relieve oneselfation 0. 5 to 10 mm/day. always anterograde. moves enzymes governs speed of damged nerve fibers. two way musical passage along an axon 16. What is bipolar neuron? 17. What is dynein? 18. What is pendymal cells? 19. What is fast anterograde transport? 20. What is fast retrograde transport? 21. What is Initial segment? 22. What is Internodes? 23. What is kinesin? 24. What is microglia? 25. What is multipolar neuron? 26. What is myelin sheath? 27. What is myelination? 28. What is neurilemma? 29. What is nodes of Ranvier? 30. What is oligodendrocyes? 31. What is retrograde transport? 32. What is Satellite cells? 33. What is the trigger district? 34. What is unipolar neuron? one axon and one dendrite. motor proteins in retrograde transport line internal cavities of the brain.Secretes and circulates CSF (cerebrospinal fluid) transport moves mitochondria, synaptic vessicles, other organelles toward the distal end of the axon for recycled material and pathogens rabies, herpes simplex, tetanus, polio virus. The scam section of nerve fiber between the axon hillock and the starting glial cell the myelin covered segments from one gap to the bordering motor proteins in anteograde transport. (supply) soldier small, wondering macophages formed white stock cell called monocytes one axon, multiple dendrites. Most common, most neuron in brain and spinal cord an insulating layer around a nerve fiber. s segmented production of the myel in sheath. thick outermost cast of myelin sheath. contains nucleus and most of its cytoplasm. gaps between the segments of myelin sheath form myelin sheathes in CNS. forms an insulating layer that speed up signal conduction movement up the axon toward the soma surround neurosoms in ganglia of PNS. put forward electrical insulation around soma. Regulate chemical environment of the neuron the axon hillock and initial segment single process steer away from the soma. Sensory from skin and organs to spinal cord 6. What are tumors? 15. what is axonal transport?
