Morphology
Knowing 'superior' (upper) and 'rectus' (a straight muscle) lets a learner infer that this is an upper/uppermost straight muscle, so the basic referent (an upper muscle) is compositional. However, the precise anatomical location (the eyeball) and the specific action (turning the eye upward and toward the midline) are specialized medical information not fully predictable from the parts, so the transparency is partial.
Etymology
Superior rectus comes from old Latin words superior meaning 'upper' and rectus meaning 'straight'. It is a straight muscle above the eye that pulls the eyeball up and a little toward the nose, so the superior rectus helps you look up and toward the nose.
