Body. The body, or gladiolus, is the longest sternal part. It is flat and considered to have only a front and back surface. It is flat on the front, directed upward and forward, and marked by three transverse ridges which cross the bone opposite the third, fourth, and fifth articular depressions.

manubrium
The sternum develops as three distinct parts: the manubrium, the body of the sternum (sometimes called the gladiolus), and the xiphoid process.

Where is the sternum?
The sternum is a flat bone located in the centre of the anterior thoracic wall. It consists of three segments; Manubrium (uppermost part, see image at R) Body (middle part) and.
What is the gladiolus bone?
an elongated, flattened bone, forming the middle portion of the anterior wall of the thorax. Its upper end supports the clavicles, and its margins articulate with the cartilages of the first seven pairs of ribs.
Where is the sternum located in the body?
The sternum is sometimes known as the breastbone. This flat bone sits at the front of the chest and connects to the ribs with cartilage. The sternum is part of the rib cage, a series of bones that protects the heart and lungs from injuries.
Which of these is not a part of the sternum?
The correct answer is (A). costal groove. The sternum has three parts, which are the manubrium, the body, and the xiphoid process. The costal groove is a feature on ribs and not the sternum.
What is sternal anatomy?
Your sternum is a bone that’s located in the middle of your chest. It’s also sometimes referred to as the breastbone. Your sternum protects the organs of your torso from injury and also serves as a connection point for other bones and muscles.

Another definition of axial skeleton is the bones including the vertebrae, sacrum, coccyx, ribs, and sternum.
Where is the sternum located on the body?
Sternum. It is connected to the first two ribs and is not completely rigid. The body, also called the blade or gladiolus, is right in the middle of the sternum. It connects to the third through seventh ribs directly and the eighth through tenth ribs indirectly. The xiphoid process is the bottom tip of the sternum.
Where does the manubrium attach to the sternum?
Ribs one and two articulate with the manubrium, but rib two articulates with only a partial facet of the manubrium at the sternal angle. The manubrium attaches to the body of the sternum, or gladiolus, at a transverse ridge, forming the sternal angle (also known as the angle of Louis).
Is the sternum part of the clavicle?
The sternum is attached to the first seven ribs and also to the clavicle, or collarbone. The sternum is made up of three parts called the manubrim, the body, and the xiphoid process.
How are the costal cartilages attached to the sternum?
The costal cartilages of the second through tenth ribs connect to the body of the sternum to form the bulk of the rib cage. Just like in the manubrium, slight concave indentations in the lateral sides of the body of the sternum provide stronger attachment points for the costal cartilages to prevent rib separation.
