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
