Morphology

rectus + medialis

The phrase is morphologically compositional: Latin-derived 'rectus' (a straight muscle) combined with 'medialis' (medial/toward the midline) yields a literal meaning of a straight muscle located toward the midline. However, the specific functional description 'turns the eyeball toward the nose' requires anatomical knowledge of extraocular muscles, so the connection is partially but not fully predictable for a B1 learner.

Etymology

Rectus medialis names the eye muscle that turns the eyeball 'toward the nose'. It comes from two Latin words, rectus meaning 'straight' and medialis meaning 'middle', so the name gives the image of a straight muscle near the middle of the eye that pulls the eye inward.
