    Study Notes

    Landry's Paralysis

    • Involves the anterior horn cells

    Myasthenia Gravis

    • Linked to a condition of impaired neuromuscular transmission

    Axonotmesis

    • Characterized by disruption of the axon, but the epineurium and perineurium remain intact

    Dystrophia Myotonia

    • Associated with a disorder of muscle stiffness and myotonia

    Neuropraxia

    • Associated with a condition of nerve damage that is reversible

    Electrodiagnosis

    • Studies the electrical activity of muscles and nerves

    Wallerian Degeneration

    • Characterized by the degeneration of the axon distal to the site of injury

    Myoneural Junction

    • Associated with a disorder of the neuromuscular junction

    Progressive Muscular Atrophy

    • Involves the anterior horn cells and is associated with Progressive Muscular Atrophy

    Syringomyelia

    • Associated with a disorder of the spinal cord

    Neurotmesis

    • Characterized by complete transaction of the nerve

    Seddon's Classification of PNI

    • Involves a classification of nerve injury into three types: Neuropraxia, Axonotmesis, and Neurotmesis
