The flashcards below were created by user AP101e2014 on FreezingBlue Flashcards. What would you like to do?


  1. Contains granular cytoplasm, mitochondria, lysosomes, a golgi apparatus, and microtubles.
    Cell Body
  2. Fines threads that form a network that extend into the axon and supports it.
    Neurofibrils
  3. Nissl bodies, membrane packets scattered throughout the cytoplasm consisting mainly of rough endoplasmic reticulum.
    Chromatophilic Substance
  4. Highly branched, provides receptive surfaces with which processes from other neurons communicate.
    Dentrites
  5. A cone-shaped thickening that the axon arises on from the cell body.
    Axon Hillock
  6. Branches off from axon.
    Collatertals
  7. Specialized ends of the fine extensions off of the axon.
    Axon Terminal
  8. Used by the axon terminal ends close to the receptive surface of another cell.
    Synaptic Knob
  9. Tiny thorn-like spines on the surface of some dentrites used as contact points for other neurons.
    Dendritic Spines
  10. When the axon conveys biochemicals produced in the neuron cell body which moves vesicles, mitochondria, ion, nutrients, and neurotransmitters to the ends of the axon.
    Axon Transport
  11. Neuroglias (found in PNS) that encase the large axons of peripheral neurons in lipid-rich sheaths.
    Schwann Cells
  12. The myelin layer coating, made of lipids and proteins, that wraps around the axon.
    Myelin Sheath
  13. Parts of Schwann cells that contain most of the cytoplasm and nuclei, found wrapped around outside the myelin sheath.
    Neurilemmal Sheath
  14. Narrow gaps in the myelin sheath between Schwann cells.
    Nodes of Ranvier
  15. Axons that lack a myelin sheath, but instead the axons lie partially or completely in a longitudinal groove of a Schwann cell.
    Unmyelinated
  16. Chromatophilic substances, membrane packets scattered throughout the cytoplasm.
    Nissl Bodies
