Which root means 'fingers' or 'toes' in anatomy?

1. Dacry-

2. Dextr-

3. Dactyl-

4. Derm-

The correct answer is: Dactyl-

The root "dactyl" comes from the Greek word "daktylos," which translates to "finger" or "toe." In anatomical terminology, "dactyl" is commonly used to refer to digits, which includes both the fingers of the hands and the toes of the feet. This is evident in medical terms such as "dactylitis," which denotes inflammation of the fingers or toes, and "polydactyly," which refers to a condition involving extra fingers or toes. Understanding the meaning of the root allows healthcare professionals to accurately interpret and use related medical terms. The other roots provided do not pertain to fingers or toes. "Dacry-" relates to tears or the lacrimal apparatus; "dextr-" refers to the right side; and "derm-" pertains to the skin. Therefore, "dactyl" is the correct choice in the context of anatomy related to fingers and toes.
