What is a Digit?

• A. A finger or toe
• B. A bone of the foot
• C. A muscle in the sole
• D. A joint in the ankle

Answer: (A)

A digit is the finger or toe—the end part of a limb. The term refers to the whole finger or toe as a unit, not to a single bone, muscle, or joint within it. That’s why it’s the best answer: it captures the entire structure you can see and count as a finger or toe, whereas the other options name specific parts inside that structure (a bone like a phalanx, a muscle in the sole, or a joint such as in the ankle). In humans there are five digits on each hand and five on each foot, and each digit is made up of multiple bones called phalanges connected by joints.
