The term "articulation sternoclavicularis" refers to the joint between the sternum and the clavicle. The word is spelled using the International Phonetic Alphabet (IPA) to better represent the pronunciation. "Articulation" is pronounced /ɑrtɪkjəˈleɪʃən/, while "sternoclavicularis" is pronounced /stɜːrnoʊkləˈvɪkjʊlərɪs/. The use of IPA is important for accurately understanding and pronouncing complex medical terms. This terminology ensures clarity and consistency among healthcare professionals and aids in effective communication.
The articulation sternoclavicularis refers to the joint between the sternum (specifically the manubrium) and the clavicle, commonly referred to as the sternoclavicular joint. It is a synovial joint classified as a saddle joint due to its unique shape, allowing for a wide range of movement and articulation.
This joint is located at the front of the thorax and is critical for the stability and mobility of the upper limb, connecting the axial skeleton to the upper appendicular skeleton. It provides both flexibility and strength to the shoulder girdle, enabling movements such as protraction, retraction, elevation, depression, and rotation of the arm.
The articulation sternoclavicularis consists of two articulating surfaces: the sternal extremity of the clavicle and the clavicular notch on the manubrium of the sternum. These surfaces are covered with articular cartilage, which helps reduce friction and absorbs shock during movement. The joint is supported by strong ligaments, including the anterior and posterior sternoclavicular ligaments, which prevent excessive movement and provide stability to the joint.
In summary, the articulation sternoclavicularis is the synovial joint connecting the sternum and clavicle. It allows for a wide range of movements, providing stability and mobility to the shoulder girdle.

The word "articulation sternoclavicularis" is a medical term used to refer to the joint between the sternum (breastbone) and the clavicle (collarbone). Let's break down its etymology:
1. Articulation: This word comes from the Latin "articulatio", which means a joint. The word "articulatio" is derived from the verb "articulare", meaning "to divide into joints". In this context, it refers to the connection or joint between bones.
2. Sternoclavicularis: This term consists of two main components:
- Sterno: This part refers to the sternum, the flat bone located in the middle of the chest. The word "sternum" itself comes from the Greek "sternon", meaning "chest".
