Fossa radialis is a latin term that pertains to a depression in the bone structure of the arm. The word is spelled using the International Phonetic Alphabet (IPA) as /ˈfɒsə rəˈdaɪəlɪs/. In this phonetic transcription, the "o" in "fossa" is pronounced as "ah," while the "a" in "radialis" is pronounced as "ay." This pronunciation aids in correctly articulating the word, which proves essential while communicating with medical professionals or while studying the human anatomy.
The term "fossa radialis" refers to a specific anatomical structure in the human body. It is a Latin term that translates to "radial fossa" in English, with "fossa" meaning a depression or hollow, and "radialis" referring to the radius bone in the forearm.
In anatomy, the fossa radialis is a small, shallow depression located on the anterior (front) aspect of the radius bone within the forearm. It is positioned just below the prominence of the radial tuberosity. The fossa radialis is often described as being oval or concave in shape, with a smooth surface.
This anatomical feature serves as an attachment site for the biceps brachii muscle, which is one of the primary muscles responsible for flexing the forearm at the elbow joint. The tendon of the biceps brachii muscle inserts into the radial tuberosity, which lies just above the fossa radialis. Therefore, the fossa radialis acts as a supportive region for this attachment site, providing stability and facilitating the movement of the biceps brachii muscle during contraction.
Understanding the precise location and function of the fossa radialis is important for medical professionals, particularly during clinical examinations or when performing procedures such as injections or surgeries involving the forearm and elbow joint.
Radial fossa, a shallow depression above the capitellum of the humerus in front, in which the margin of the head of the radius rests when the elbow is in extreme flexion.

The word "fossa radialis" is a Latin term. In Latin, "fossa" means "ditch" or "trench", and "radialis" refers to "related to the radius".
In anatomy, the term specifically refers to a depression or groove on the radial side (the side of the thumb) of the wrist. The radial fossa provides attachment for certain tendons and other structures.
