The jugular notch, also known as the suprasternal notch or presternal notch, is the prominent indentation located at the superior border of the manubrium (the upper part) of the sternum (breastbone).
Detailed Explanation
The jugular notch is a clinically significant anatomical landmark. Here's a more detailed breakdown:
- Location: It sits centrally at the base of the neck, between the medial ends of the two clavicles (collarbones).
- Palpation: It's easily palpable (can be felt through the skin) and serves as a key reference point for various medical examinations and procedures.
- Formation: It's formed by the curved upper border of the manubrium.
- Surrounding Structures: The clavicular notches are located on either side of the jugular notch, where the clavicles articulate with the sternum.
Clinical Significance
The jugular notch is used as a reference point for:
- Central Venous Catheterization: Insertion of central lines.
- Tracheostomy: A surgical procedure to create an opening in the trachea.
- Chest Radiography: Evaluating the position of structures in the chest.
- Physical Examination: Assessing the position of the trachea and identifying any masses or abnormalities in the neck.
Summary
In simple terms, the jugular notch is the dip you can feel at the top of your breastbone in the middle of your neck. It is a useful landmark for medical professionals and is important for several clinical procedures and physical examinations.
