Morphology
Both constituents are compositional: 'urethral' specifies relation to the urethra and 'sphincter' denotes a muscle that closes an opening. A B1 learner who knows these parts can directly infer this refers to the sphincter muscle around the urethra that controls urine release, so the term is transparent.
Etymology
Urethral sphincter is a ring-shaped muscle called a sphincter that sits around the urethra and works like a small valve. When it tightens it 'stops the flow' and when it relaxes it lets urine pass, so the name helps you remember it controls 'passing urine'.
