Understanding the Jugular Notch: A Key Anatomical Landmark You Should Know The jugular notch, also known as the jugular indent, is a subtle but significant anatomical feature found at the base of the skull. Though often overlooked in casual observation, this structure plays a critical role in medicine, human anatomy, and even evolutionary biology. Whether you're a medical professional, student, or simply curious about human anatomy, understanding the jugular notch is essential for recognizing key landmarks in the skull and appreciating its clinical relevance. ### What Is the Jugular Notch? The jugular notch is a depression located medially on the posterior border of the occipital bone, just superior to the jugular foramen. It serves as a palpable landmark that helps identify the underlying venous structures, particularly the internal jugular vein (IJV), which is vital for blood drainage from the brain and head.
