三角筋と斜角筋

I'm sorry, but it seems there is a misunderstanding. The term "三角筋と斜角筋" is not a Spanish word; it is Japanese. In Japanese, "三角筋" refers to the deltoid muscle, and "斜角筋" refers to the scalene muscles. If you need definitions for these terms in the context of anatomy or any other information, please let me know! tuntematon
