Question

read the passage. have you ever bumped your elbow and felt a tingling pain? many people call that \hitting your funny bone.\ however, the funny bone actually isnt a bone at all. humans have a nerve, called the ulnar nerve, that runs from the neck to the pinky finger. for most of its length, this nerve is cushioned by muscle or fat—except at the back of the elbow. bumping this area causes an electric - like shock of pain that feels different from a stubbed toe or a bump on the head. some believe that this strange or funny - feeling is where the funny bone gets its name! based on clues in the passage, what is the most likely reason that you feel an unusual pain after bumping the back of your elbow? this is the area where the ulnar nerve comes to an end. this is an area where the ulnar nerve is poorly protected. this is an area where the ulnar nerve is pinched by fat and muscle. this is the area where the ulnar nerve first enters the bone.

Explanation:

The passage states the ulnar nerve is cushioned by muscle/fat for most of its length, except at the back of the elbow. Bumping this unprotected area causes the unusual pain, so the nerve is poorly protected here.

Answer:

This is an area where the ulnar nerve is poorly protected.
