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
