Peripheral Nervous System (PNS)

Karten in diesem Stapel (36)

  1. 1Peripheral Nervous System (PNS)Connects the central nervous system to the body’s organs and musclesPeripheral Nervous System (PNS)
  2. 2Central Nervous System (CNS)Central: brain and spinal cord->these are composed of interneuronsCentral Nervous System (CNS)
  3. 3PNS: Autonomic nervous system (ANS)dual functions: arousal & returning the body to its resting statePNS: Autonomic nervous system (ANS)
  4. 4PNS: Somatic nervous system (skeletal nervous system)PNS: Somatic nervous system (skeletal nervous system)
  5. 5ANS: Sympathetic Nervous SystemarousingANS: Sympathetic Nervous System
  6. 6ANS: Parasympathetic Nervous SystemcalmingANS: Parasympathetic Nervous System
  7. 7Glial Cellsthe pathological sensors of the brain; the glue; ~90% of brainGlial Cells
  8. 8Glial Cells: Astrocitesthe babysitters
  9. 9Glial Cells: Oligodendrocytesinsulators of the CNS
  10. 10Glial Cells: Schwann Cellsinsulators of the PNS
  11. 11Glial Cells: MicrogliaThe CNS’ “Immune System”
  12. 12Sensory NeuronsBring in incoming information
  13. 13InterneuronsConnect and process information
  14. 14Motor NeuronsAttach to muscle fibers
  15. 15The Neuron: Cell Body (Soma)nucleus with chromosomes
  16. 16The Neuron: Dendritesreceive information from other neurons
  17. 17The Neuron: Axontransmits information to other neurons, muscles, and glands
  18. 18The SynapseJunction between one neuron’s axon and another’s dendrites/cell body;Neurotransmitters cross the synapse;Plays a fundamental role in the communication between neurons
  19. 19MyelinInsulating layer of fatty material; Composed of glial cells Helps efficient transmission of signals to other cellsMyelin
  20. 20Myelin: nodes of RanvierGaps in myelin sheathMyelin: nodes of Ranvier
  21. 21The Action PotentialThe Action Potential
  22. 22The Resting PotentialHigher conc K+ inside neuron & higher conc Na+ outside neuronThe Resting Potential
  23. 23Na+/K+ Pumprestores resting state charge
  24. 24The Refractory Periodtime following an action potential; Another action potential can’t occur during the refractory periodThe Refractory Period
  25. 25Excitatory MessagesProduce Excitatory PostSynaptic Potentials (EPSPs)
  26. 26Inhibitory MessagesProduce Inhibitory Post-Synaptic Potentials (IPSPs)
  27. 27Neurotransmitterschemicals that transmit information across the synaptic gap (cleft)
  28. 28Anatomy of the SynapseAnatomy of the Synapse
  29. 29What happens to neurotransmitters in the synapse: ReuptakeNeurotransmitters are absorbed back into the presynaptic neuron
  30. 30What happens to neurotransmitters in the synapse: Enzyme Deactivation (Disassembly)Neurotransmitters are broken down by enzymes in the synapse
  31. 31What happens to neurotransmitters in the synapse: AutoreceptorsNeurotransmitters bind to autoreceptor sites on the presynaptic neuron
  32. 32Neurotransmitter: Acetylcholine (ACh)Functions MalfunctionsNeurotransmitter: Acetylcholine (ACh)
