Question

To test peripheral nerve regeneration, a doctor cut and sewed his own _____ nerve.

A. ulnar
B. external cutaneous
C. radial
D. median
E. None of the above

Answer 1

The doctor most likely cut and sewed his own ulnar nerve to test peripheral nerve regeneration.

Step-by-step explanation:

A doctor cut and sewed his own _____ nerve. This is a reference to an actual event where a doctor tested peripheral nerve regeneration on himself. However, without additional context or the name of the doctor, this becomes a hypothetical scenario for which we cannot provide a specific nerve name as all choices are peripheral nerves. Therefore, the correct answer is E. None of the above, since we cannot definitively fill in the blank with the information given.
