forearm

The forearm is the part of the arm between the elbow and the wrist. Inside it are two bones, the radius and the ulna, along with muscles, tendons, blood vessels, and nerves. Together, they help the hand and wrist move in many ways. Because of that, this area is involved in both fine actions, like writing or buttoning a shirt, and stronger actions, like lifting, pulling, or pushing.

In everyday language, the word usually appears in simple physical descriptions. A person may have a watch on this part of the arm, a scratch across it, or a tattoo on it. Someone might lean on a table with both forearms, cover their face with one, or feel soreness there after exercise. The word is common when talking about sports, work, health, and ordinary movement.

This part of the body is easy to overlook because it works so often and so quietly. Yet it helps connect what you want to do with what your hand can actually do. From carrying groceries to turning a key, it supports a huge number of daily actions without asking for much attention.
