Morphology

smaller + pectoral + muscle

The phrase is fully compositional: 'smaller' (comparative size) modifies 'pectoral' (pertaining to the chest) and 'muscle' (body tissue), so the overall meaning — a chest muscle that is smaller in size — follows directly from the constituents. This is a descriptive anatomical noun phrase using standard English composition and is cross-linguistically regular, so a B1 learner who knows the three words would readily infer the meaning.

Etymology

Smaller pectoral muscle is a simple name: pectoral comes from an old word for 'chest' and smaller shows it is the little muscle under the main chest muscle. So the name fits its job of pulling the shoulder blade down and helping lift the ribs.
