When a medical term has three syllables which syllable gets the accent when pronounced?

In medical terminology, the syllable that receives the primary stress is typically the one before the final syllable. This is known as the penultimate syllable. For example, in the term "thorax," the emphasis is placed on the second syllable, "tho."

However, there are exceptions to this rule. Some terms have the primary stress on the final syllable, known as the ultimate syllable. For example, the term "peritonItis" has the emphasis on the third syllable, "Itis."

Additionally, some terms have secondary stresses on syllables other than the penultimate or ultimate syllable. These are usually indicated by a less pronounced emphasis. For example, in the term "esophAgUs," there is a secondary stress on the first syllable, "es."
