Which statement accurately describes axonotmesis?

Which statement accurately describes axonotmesis?

• A. Complete disruption of the nerve
• B. Injury causing loss of function and Wallerian degeneration
• C. No regeneration potential
• D. Partial nerve injury without loss of function

Answer: (B)

Axonotmesis refers to a type of nerve injury in which the axon is damaged while the surrounding connective tissue structures, such as the nerve sheath, remain intact. This condition leads to a loss of function due to the disruption of the nerve signal transmission along the axon. In this scenario, Wallerian degeneration occurs, which is a process where the distal segment of the axon (the portion furthest from the nerve cell body) undergoes degeneration after the injury. This type of injury allows for the potential of regeneration, as the intact connective tissues provide a supportive pathway for the regrowth of the axon. Consequently, the statement about injury causing loss of function and Wallerian degeneration accurately captures the essence of axonotmesis and reflects the biological processes that occur after such an injury.
