The word "腮腺" is formed by combining the character "腮", meaning cheek, which incorporates the body radical "月" and phonetic component "思", with the character "腺", meaning gland, which similarly uses the body radical "月" and phonetic component "泉". Together, they create a compound term that literally translates to "cheek gland", directly referring to the parotid gland located in the cheek area.
