In this article, I will explain the “sternum” in detail.
The sternum is a long bone in the center of the human chest, forms the rib cage together with the ribs, and has the role of protecting important organs such as the heart and lungs. This article will also touch on the structure and function of the sternum, as well as common diseases that can occur around the sternum and how to treat them. By deepening understanding, you will be able to correctly grasp the cause of chest problems and pain, and lead to appropriate responses and treatments.
Please use this article to deepen your understanding of the body.

What is the sternum
The sternum is a long, flat bone located in the center of the human chest. Together with the ribs, it forms the rib cage and plays a role in protecting important internal organs such as the lungs and heart. In addition, the sternum forms part of the central axis, which is important for maintaining body posture, and is often depicted in a very prominent position in human anatomy diagrams.
How to read sternum
The sternum is read as “today.” The Chinese character “chest” means chest, and “bone” means bone. Therefore, in literal translation, it means “thoracic bone,” and you can tell from its name that it is a bone located in the chest.
Characteristics of the sternum
The sternum consists of three major parts. It is the “body (body)” at the top, the “knuckles (knuckles)” in the middle, and the “joint with the ribs (ribs)” at the bottom. Each of these parts has characteristics in shape and function, and plays an important role in understanding the structure of the chest.
The location and position of the sternum
In the human anatomy diagram, the sternum is located in front of the chest, above the midline. The 1st rib is connected to the 7th rib by rib cartilage, and this structure enhances the stability of the rib cage and at the same time enhances protective function for internal organs.
How to memorize sternum
An easy way to remember the sternum is to compare its shape to a “tie.” The extended part at the top is equivalent to the large part of a tie tied at the neck, the “body” is the long part of a tie, and the “sword proboscis” is equivalent to the tip of a tie that is thin and sharp.
English/Latin for sternum
The sternum is represented as “Sternum” in English. It is also called “Sternum” in Latin. These words are widely used as medical terms, and this name is also used in international literature and conferences.
Trivia about sternum
The texture of the sword, which is at the bottom of the sternum, may change with age. In older people in particular, it is known that the sword proboscis changes from flexible to hard. Using this characteristic, it may be useful for estimating the age of dead bodies, etc.
Tissues associated with the sternum: characteristics of the ribs
The ribs are one of the bones that make up the human chest, and usually one adult has 12 pairs of ribs symmetrically on the left and right. Of these, the top 7 pairs directly connect to the sternum, and these are called “true ribs.” The 8th to 10th ribs connect indirectly through cartilage rather than directly to the sternum and are called “false ribs.” Furthermore, the last two bodies have no anterior cartilage junction, and are called “floating ribs.”
Tissue associated with sternum: location and position of ribs
The ribs form the sides and back of the rib cage, with the upper part just below the base of the neck and the lower part above the lower back. Each rib of a true rib directly connects to the sternum, and this strong connection stabilizes the rib cage and protects vital organs such as the heart and lungs. The ribs have a curved shape, which allows the rib cage to expand and contract, and supports breathing.
Tissue associated with the sternum: rib trivia
Ribs have very high elasticity, but with age, this elasticity decreases, making them more prone to fractures. Rarely do people have more ribs than they have fingers. This phenomenon is called an accessory rib and is usually left unattended, but in some cases it can cause pain or other medical problems. The ribs are supported by small muscles. These muscles play an important role in thoracic breathing.
In the past, there was a superstition that “women have one more rib than men,” but there is no scientific basis at all. Both men and women usually have 12 pairs of ribs.
The ribs do more than just protect the chest; they also perform an important function during the breathing process. They are supported by the sternum and work together to enable breathing, which is essential for our vital activity. We may not be aware of it on a daily basis, but we should have a deep appreciation for this complex and elaborate system.
Sternum quiz with correct answers
Q: What bone is the sternum connected to?
A: The sternum is connected to the ribs through rib cartilage. This connection greatly contributes to the stability and protective function of the rib cage.
summary
This time, I explained the location and position of the “sternum”, how to memorize it, and the English and Latin notation.
How was it?
I would be happy if reading this article deepened my understanding of anatomy.
Learning is a long, never-ending journey, but I sincerely wish you all the best. Let's continue to study together and work hard for the national exam!
Please look forward to the next blog.
