What is the primary meaning of the combining form dermat/o?

The combining form "dermat/o" specifically refers to the skin. This stems from the Greek word "derma," which translates to "skin." In medical terminology, many terms are constructed using combining forms that often originate from Greek or Latin roots.

For example, when combined with other suffixes or prefixes, dermat/o forms various medical terms related to skin conditions or treatments, such as dermatology (the study of skin) or dermatitis (inflammation of the skin). Understanding this combining form is essential in the field of medical billing and coding, as it helps in accurately interpreting and coding diagnoses and procedures related to skin disorders.

Other choices like rigid, joint, or muscle pertain to different anatomical structures or conditions unrelated to the skin, making them incorrect in this context.
