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


  1. Specialized masses of nerve tissue where cell bodies of some unipolar neurons aggregate (located outside the brain and spinal cord.
    Ganglia
  2. Many processes arising from cell body (one axon and multiple dentrites). Found in brain and spinal cord.
    Multipolar Neuron
  3. Two processes (one on each end. One axon one dentrite) Found in eyes, nose, and ears.
    Bipolar Neuron
  4. Single process extends from cell body and then forks into two branches (single axon) One branch (peripheral) forms dentrites while the other (central) enters the brain/spinal cord. Found in ganglia outside the brian/sprinal cord.
    Unipolar Neuron
  5. Nerve cells specialized the react the physical and chemical changes in its surroundings.
    Neuron
  6. Center of nerve cell.
    Nucleus
  7. A bundle of axons in the PNS.
    Nerve
  8. Axons that lack a myelin sheath, but instead the axons lie partially or completely in a longitudinal groove of a Schwann cell. (gray matter).
    Unmyelinated
  9. Parts of Schwann cells that contain most of the cytoplasm and nuclei, found wrapped around outside the myelin sheath.
    Neurilemmal Sheath
  10. Neuroglias (found in PNS) that encase the large axons of peripheral neurons in lipid-rich sheaths.
    Schwann Cells
  11. The myelin layer coating, made of lipids and proteins, that wraps around the axon.
    Myelin Sheath
  12. An axon with a Myelin sheath. (white matter).
    Myelinated
  13. Conducts impulses from receptors in peripheral body parts into the brain or spinal cord. Most unipolar some bipolar. (afferent).
    Sensory neurons
  14. Relays information between neurons in brain and spinal cord. Multipolar. (association/internuncial).
    Interneurons
  15. Conducts impulses from the brain or spinal cord out to effectors - muscles or glands. Multipolar. (efferent).
    Motor Neurons
