The most likely cause of a suprasternal pulse in an adult is an aortic arch aneurysm, while the most likely cause in a child is coarctation of the aorta.
What does suprasternal notch articulate to?
Jugular notch (aka, suprasternal notch) is on the superior border of the manubrium.

Costal notches articulate with the costal cartilages of the ribs (“costal” refers to the ribs).

How do you find a suprasternal notch?
Think of it like a doorway. Behind that notch, you’ll find the superior mediastinum, which is basically the space between your lungs. It’s where all sorts of essential structures hang out. Let’s explore what’s hiding behind this anatomical gateway:
The Key Players Behind the Suprasternal Notch
The Thymus: This little gland, sitting right behind the notch, plays a big role in your immune system, especially when you’re a kid. It’s responsible for making those special cells called T-lymphocytes that help fight off infections. Think of it as your body’s own personal army.
The Great Vessels: These are the big blood vessels that carry blood to and from your heart. Right behind the notch, you’ll find the brachiocephalic trunk, the left common carotid artery, and the left subclavian artery. These arteries are responsible for delivering oxygen-rich blood to your head, neck, and arms. And don’t forget the superior vena cava, which carries deoxygenated blood back to the heart.
The Vagus Nerve: This important nerve is responsible for controlling a wide range of bodily functions, including heart rate, digestion, and breathing. It also carries sensory information from your internal organs.
The Trachea: This is your windpipe, the passageway that carries air to your lungs. You can feel the trachea right below the suprasternal notch if you swallow.
The Esophagus: This muscular tube carries food from your mouth to your stomach. You can’t actually feel the esophagus, but it’s nestled behind the trachea.
A Visual of the Suprasternal Notch and its Surroundings
Imagine the suprasternal notch as the entrance to a busy street. The thymus is like a small building on the corner, while the great vessels are like a network of large pipes carrying water throughout the neighborhood. The vagus nerve is like a series of cables connecting different parts of the city, and the trachea and esophagus are like two tunnels transporting air and food.
Why is the Suprasternal Notch Important?
Besides being a cool anatomical landmark, the suprasternal notch is important for several reasons:
Medical Procedures: Doctors use the suprasternal notch to locate other anatomical structures during medical procedures, especially those involving the chest. Think of it like a map for medical professionals.
Chest Compression: During CPR, the suprasternal notch is the point where you apply pressure to the chest to help circulate blood. This is crucial in emergency situations to keep the heart beating.
Positioning: It’s a useful reference point when positioning patients for medical exams or surgery. This helps ensure the patient is positioned correctly and comfortably.
FAQs about the Suprasternal Notch
1. Can I Feel My Thymus Behind the Suprasternal Notch?
Unfortunately, no. The thymus is a small, soft gland that’s tucked away behind the breastbone. You can’t feel it.
2. What Happens If There’s Something Wrong with the Structures Behind the Suprasternal Notch?
Depending on the specific structure involved, problems behind the suprasternal notch can cause a range of symptoms, like difficulty breathing, chest pain, swelling in the neck, or a change in your voice. If you experience any of these symptoms, it’s important to see a doctor for an accurate diagnosis.
3. What Can I Do to Take Care of the Structures Behind the Suprasternal Notch?
There’s no special care you need to take to protect the structures behind the suprasternal notch. Living a healthy lifestyle, including eating a balanced diet, getting regular exercise, and avoiding smoking, helps keep your entire body healthy, including the area behind the suprasternal notch.
4. Can I See My Suprasternal Notch in the Mirror?
Yes, if you look in the mirror and tilt your head back slightly, you can usually see the notch at the top of your breastbone.
5. How Can I Find My Suprasternal Notch?
The suprasternal notch is easy to find. Feel for the bony prominence in the middle of your neck, just below your Adam’s apple. Now, gently slide your fingers down the bony structure (your sternum) until you feel a small dip. That’s your suprasternal notch.
Understanding the suprasternal notch is like having a little cheat sheet to the anatomy of your chest. It’s a gateway to a whole world of important structures that keep you alive and functioning. So, next time you feel your necklace resting on that little dip at the top of your breastbone, remember that it’s not just a bony landmark, but a gateway to the heart of your being.
