Antebrachium (Forearm) – Meaning and Usage in Medical English

The antebrachium is the medical term for the forearm: the part of the arm between the elbow and the wrist, containing the radius and ulna.

👁 What Does “Antebrachium” Mean?

The antebrachium is the forearm — the part of the upper limb between the elbow and the wrist. It contains two bones: the radius (on the thumb side) and the ulna (on the little-finger side).

The word comes from Latin: ante (“in front of” or “before”) and brachium (“arm”). In anatomy, the brachium is the upper arm, so the antebrachium is the segment that comes after it. The adjective is antebrachial.
