Sternal is an adjective that pertains to the sternum, which is the long, flat bone situated in the center of the chest. It originates from the Latin word "sternum," which means "breastbone." When something is described as sternal, it means it is related to or associated with the sternum.
In anatomical terms, sternal refers to any structure, condition, or process that involves or affects the sternum. For example, sternal pain relates to any discomfort or sensation experienced in the area of the breastbone. This can be caused by various factors such as injury, inflammation, or strain.
Furthermore, sternal angle, also known as the angle of Louis, is a notable anatomical landmark that refers to the angle where the manubrium (upper part of the sternum) meets the body (central part of the sternum). This angle holds significance in various clinical and radiological examinations as it marks the level of the second rib and the intervertebral disc between the fourth and fifth thoracic vertebrae.
In summary, sternal is an adjective used to describe anything connected to the sternum. It encompasses various anatomical structures, conditions, and processes related to the breastbone, including pain, angles, and other medically significant aspects.
