Sounds like an extensor problem to me.

It's been almost a year since anatomy but ,isn't that just median n at the wrist?

The question asks for a specific muscle.. not the nerve involved or the group of muscles (flexor/extensor/abductor)

 

[slz1900]

Extensor pollicis longus (the movement is called retropulsion)

 

[Entadus]

Is the hand face-up or face-down on the table?
