Morphology
The term is fully compositional: 'musculus' = muscle, 'triceps' = three-headed (tri- + ceps) and 'brachii' = of the arm, so the phrase literally denotes the three‑headed muscle of the arm responsible for extension. Although technical and Latinized, the parts follow standard anatomical naming conventions (common across many languages), so a learner who knows the constituent elements can transparently derive the MWE's meaning.
Etymology
Musculus triceps brachii comes from Latin words. musculus means 'little mouse' because people thought muscles looked like small mice under the skin, triceps means 'three-headed', and brachii means 'of the arm', so the name points to the 'three-headed muscle of the upper arm that straightens the elbow'.
