Shaped somewhat like a sword, the sternum is a fascinating bone with multiple anatomical features and muscle attachments. This Anatomy lecture will help you memorize all these interesting features and retain this information, with fun mnemonics.

But that is not all!

▬ 📃 Sternum Bone ▬▬▬▬▬▬▬▬▬▬
Just as a bonus, our educator Dr. Hina Khan also highlights three common sternum bone deformities that the examiner might ask you during your examination.

So, the sternum can also be termed as the breastbone, due to its placement. It covers the anterior side of your chest cavity. If you palpate right in the middle of your chest, you can feel the sternum, with ribs coming out of it. Your sternum and ribs work together to protect the organs in your thorax like your heart, lungs, and esophagus.

The sternum is divided into three main sections:

▬ 📜 Manubrium ▬▬▬▬▬▬▬▬▬▬
The upper T-shaped portion

▬ 📃 Body ▬▬▬▬▬▬▬▬▬▬
The middle portion, making up the sword

▬ 📜 Xiphoid Process ▬▬▬▬▬▬▬▬▬▬
The lower end of the sternum, making up the tip of the sword

▬ 📃 Sternum Muscle Attachments ▬▬▬▬▬▬▬▬▬▬
This lecture will also detail all the muscle attachments supported by the sternum bone.

These include your chest muscles, abdominal muscles, and most importantly the diaphragm. So, all of these muscles combined with the particular shape of the sternum allow the flexibility required for the process of inspiration and expiration.

It provides an attachment point for the ribs, making space for the lungs to expand and contract during respiration.

So at the end of this lecture, you will get a full understanding of the gross anatomy of the sternum bone, along with many important facts.
