The sternal angle, or Angle of Louis, is an important and easily palpable anatomical landmark located at the junction of the manubrium and body of the sternum. While often confused, this bony ridge corresponds to the intervertebral disc between the fourth and fifth thoracic vertebrae (T4/T5), definitively answering the question of whether the sternal angle is T2 or T4.

As a cornerstone of physical examination and anatomical orientation, the sternal angle is a vital landmark. Understanding **what is 4cm above the sternal angle** involves recognizing its relationship to the manubrium, the top segment of the sternum, and its various clinical implications.

Approximately 95% of developing T-cells are eliminated within the thymus because they are self-reactive or lack proper receptor affinity. The thymus is indeed the key lymphatic organ that is located behind the sternum, playing a vital role in the early development of a robust immune system.

Over 200,000 Americans undergo chest X-rays each year, which can reveal details about the structures located below the breastbone, an area often referred to simply as the “thing below your chest”. The region houses several important anatomical features, including a small, bony extension of the sternum, the primary muscle for breathing, and the uppermost part of the abdomen. Understanding these different components is key to deciphering symptoms and promoting overall health.

An estimated one-third of individuals with a congenital chest wall abnormality like pectus excavatum have a family member with the condition. It's a common question whether a visible separation or “gap” between the pectoral muscles is just normal anatomical variation or a sign of an underlying issue. The simple answer is that for most people, a chest gap is a normal and harmless genetic trait.

The sternum, or breastbone, is a long, flat bone shaped somewhat like an upside-down sword, protecting the heart and lungs from injury. Understanding what should a normal sternum look like, from its three distinct segments to common variations, is key to recognizing potential health concerns.

Fact: The anatomical name for the entire chest region is the thorax. In detailing the answer to *What is the name of the upper chest area?*, the key is understanding that there isn't one single term but several, describing different layers of anatomy, from bone to muscle.

The vast majority of people can feel a visible dip at the base of their neck, right above the breastbone. This large, palpable depression is known by two main medical names, providing the direct answer to the question, **what is the notch in your throat called?**.

Anatomical landmarks are crucial for medical professionals, and a prominent depression at the base of the neck provides one such reference point. So, **what is another name for the jugular notch**? It is also commonly called the suprasternal notch, a palpable landmark on the superior aspect of the sternum.

A thorough understanding of chest anatomy is fundamental for medical professionals performing physical assessments. So, what are the landmarks of the chest anatomy? These identifiable surface features, from the sternal angle to the scapulae, are critical for locating underlying organs and diagnosing conditions.
