Axonotmesis includes discontinuity in: | PGIMER MCQs for MD MS Preparations


Axonotmesis includes discontinuity in: 

a. Perineurium 
b. Epineurium 
c. Endoneurium 
d. Axon 
e. Myelin sheath


Ans : (D) Axon ; (E) Myelin sheath


• Axonotmesis is characterized by axonal and myelin sheath damage that results in loss of continuity with the cell body and its end organ. There is preservation of the endoneurium, perineurium, and epineuriurn. This type of nerve damage may cause paralysis of the motor, sensory, and autonomic functions. If the force creating the nervedamage is removed in a timely fashion, the axon may regenerate, leading to recovery.
