Inferior rectus and inferior oblique
I know you're right. I was just so uncomfortable picking an answer with "inferior rectus" because damage to the inferior rectus does nothing to explain the clinical findings of impaired upward gaze. Unless the muscle is physically stuck and can't relax or something
Agreed. Why would a dysfunctional inferior rectus contribute to impaired upward gaze??? I eliminated that answer choice and got it wrong :(
in the last sentence it asks you to assume an "entrapment", so it is actually the inferior rectus which is the cause of the upward gaze palsy. The entrapped muscle is functionally trapped in it's shortened position, thereby not allowing the orbit to gaze upward.
hi, but inferior oblique moves up and in and not out
