Did you know?
- The first part of the word, 括約, means 'tightening up' or 'binding', a concept used in both anatomy and legal contracts in Japanese.
- The first character, 括, is the same one used in the word for parentheses, 括弧 (kakko), representing the way the muscle 'encloses' or 'brackets' an opening.
- The term 括約筋 is a complete conceptual translation of the New Latin 'sphincter', meaning Japanese speakers did not adopt the sound of the word but instead built a new word from scratch using Kanji.
