PCE Studying Questions with Complete Solutions Neurapraxia - ANSWER Injury to nerve that causes a transient loss of function (conduction block ischemia); nerve dysfunction may be rapidly reversed or persist a few weeks, e.g., compression. Axonotmesis - ANSWER Injury to nerve interrupting the axon and causing loss of function and Wallerian degeneration distal to the lesion; with no disruption of the endoneurium, regeneration is possible, e.g., crush injury. Neurotmesis - ANSWER Cutting ...
