What suffixes between -algia -otomy and -rrhea requires the use of combining words?

You're asking about suffixes that require combining forms to be used in medical terminology. Here's a breakdown:

* -algia (pain): This suffix usually combines with a word root describing the affected body part. For example:

* Cephalalgia (headache): "cephal-" (head) + "-algia" (pain)

* Myalgia (muscle pain): "my-" (muscle) + "-algia" (pain)

* -otomy (cutting, incision): This suffix also requires a combining form to specify the location or structure being cut. Examples:

* Tracheotomy (incision into the trachea): "trache-" (trachea) + "-otomy" (incision)

* Craniotomy (incision into the skull): "crani-" (skull) + "-otomy" (incision)

* -rrhea (flow, discharge): While not always requiring a combining form, it often does to specify the type of flow or discharge. Examples:

* Diarrhea (excessive watery stool): "di-" (through) + "-rrhea" (flow)

* Rhinorrhea (runny nose): "rhino-" (nose) + "-rrhea" (flow)

Combining forms are essential in medical terminology because they allow for precise and concise communication about body parts, functions, and conditions.

Important Note: Not all suffixes need combining forms. Some, like "-itis" (inflammation), "-emia" (blood condition), and "-osis" (abnormal condition), often stand alone or combine with simpler prefixes like "hyper-" (excessive) or "hypo-" (deficient).
