Question 77

Question:

A 25-year-old man who has suffered blunt trauma to his head has a suspected injury to his superior rectus muscle. What eye movements might be compromised if this indeed were the case?

Correct Answer: D.  Adduction and elevation

Simple definition question but important! The superior rectus muscle is a simple bridge-like muscle above the eye that operates dorsomedially and so results in elevation and adduction of the eye. The superior oblique muscle is responsible for depressing and abducting the eye while the inferior oblique muscle is responsible for elevating and abducting the eye.
