Which root means chest?

Which root means chest?

• A. Stoma
• B. Sub
• C. Thorac
• D. Trans

Answer: (C)

Recognizing body-region roots helps pinpoint location in anatomy terms. The root thorac- comes from the thorax, the chest. It is used to form words about the chest, such as thoracic (relating to the chest), thoracentesis (draining fluid from the chest), and thoracotomy (opening into the chest). The other roots don’t refer to the chest: stoma means mouth or an opening; sub means under or beneath; trans means across or through. So thorac- is the root that means chest.
