Antibrachiums are a part of the human body, also known as the forearm, which extends from the elbow to the wrist. There are several synonyms for this word that can be used interchangeably such as the lower arm, cubit, radius, and ulna. These terms are all anatomical references to the same part of the body, and commonly used in medical terminology. Additionally, the forearm may also be referred to as the intermediate part of the upper limb or the antebrachial region. Regardless of the terminology used, the antibrachium is a significant part of our anatomy that is essential for many day-to-day activities such as typing, writing, and grasping objects.
