Animal Behavior College (ABC) Externship Practice Test

The combining form or(o) refers to which part of the body?

Ear Mouth Organ Bone

Correct Answer:

Bone

Explanation:

Combining forms are the building blocks used in medical terminology to name body parts. In this quiz, the form or(o) is used to represent a bone. That makes bone the best answer because the question is testing your ability to apply the course’s specific mapping of combining forms to body parts. While other sources may map or/o to the mouth in different contexts, this particular test teaches or/o as bone, so the correct choice aligns with that convention. The other body parts don’t fit the mapping for or(o) here, reinforcing how the test expects you to apply the given terminology.
