Morphology
musculus + sphincter + ani + externus
Each constituent directly contributes to the overall meaning: musculus = muscle, sphincter = a closing/regulating muscle, ani = of the anus (genitive), externus = external. The phrase is a compositional Latin anatomical name meaning the external sphincter muscle of the anus, so a learner who knows the parts can derive the full meaning.
Etymology
Musculus sphincter ani externus is a Latin name whose parts are musculus meaning 'muscle', sphincter meaning 'squeeze', ani meaning 'anus' and externus meaning 'outside'. So it is a ring of muscle around the anus that you can tighten when you want, which is why it 'controls the opening' and gives 'voluntary' control over bowel movements.
