Antebrachium is a medical term referring to the forearm. Its spelling follows the Latin roots of the word: ant- meaning "before" and brachium meaning "arm." IPA phonetic transcription for antebrachium is /æn.ti.ˈbrə.ki.əm/. The stress of this word falls on the third syllable, -brach-, which is pronounced with a schwa sound. The pronunciation of this word may seem intimidating, but it's essential for medical professionals to understand and use correct terminology to ensure precise communication with colleagues and patients.
The term "antebrachium" refers to the anatomical region of the upper limb or forelimb, specifically referring to the area between the elbow and the wrist. It is commonly known as the forearm. This region is found between the distal humerus bone of the upper arm and the proximal carpal bones of the wrist.
The antebrachium includes two bones, the radius and the ulna, which are positioned parallel to each other and run the length of the forearm. These bones are crucial for the movement and support of the hand and wrist joints. The radius is located on the side of the arm where the thumb is located, while the ulna is positioned on the opposite side.
Functionally, the antebrachium plays a significant role in providing both stability and mobility to the upper limb. It enables the articulation of the elbow joint, allowing flexion and extension movements. Additionally, it allows rotation of the forearm, contributing to activities such as pronation (turning the palm downward) and supination (turning the palm upward). These movements are crucial for various daily activities, such as writing, typing, grasping objects, and performing fine motor skills.
Overall, the antebrachium encompasses the upper portion of the forearm and is formed by the radius and ulna bones. It serves as a crucial link between the elbow and the wrist, enabling vital movements and supporting the functionality of the hand and wrist joints.

The word "antebrachium" is derived from Latin. It combines the prefix "ante-" meaning "before" or "in front of", and "brachium" meaning "arm". So, "antebrachium" literally translates to "before the arm" or "in front of the arm". It typically refers to the part of the arm between the elbow and the wrist.
