Sulcus

A groove or furrow on the surface of a bone, often accommodating tendons, vessels, or nerves. The intertubercular sulcus (bicipital groove) of the humerus guides the long head of the biceps tendon.

Understanding the term "Sulcus" is essential for studying human anatomy because it provides precise language for describing body structures, their positions, and their relationships. Standardized anatomical terminology ensures clear communication among healthcare professionals, researchers, and students worldwide.
