Morphology
The parts 'lateral' (relating to the side) and 'rectus' (a straight muscle) allow a learner to infer this refers to a muscle located on the side, so some meaning is transparently compositional. However, the precise anatomical referent (that it is an eyeball muscle) and its specific function (moving the eye outward) are technical details not fully predictable from the constituents alone, making the overall term only partially transparent to a B1 learner.
Etymology
Lateral rectus comes from old Latin words: lateral meaning 'side' and rectus meaning 'straight'. This muscle runs straight along the outer side of the eye and pulls the eye outward, so the name explains that it moves the eye to the side.
