What are the 3 basic functions of the sternum?
The sternum, or breastbone, is a long, flat, bony plate that forms the most anterior section of the rib cage. The primary function of the sternum is the protection of the heart, lungs, and blood vessels from physical damage. The sternum is made of the manubrium, the gladiolus, and the xiphoid process.
Does the sternum protect the heart?
The sternum, or breastbone, is a long flat bone in the center of the chest. It protects the heart and also serves as the connection point for the costal cartilage.
What does the sternum articulate with and what is its function?
Introduction to Sternum Bone Anatomy The segments fuse to form a long, flat bone. The sternum articulates with the clavicles and costal cartilages of the ribs. It also covers and protects the heart.
Does the sternum provide support?
The bones act as levers and also form joints that allow muscles to pull on them and produce movement. Support and protection – the bones of the skeleton provide support for the body and also protect the organs found within it. Examples of bones that contain marrow are the pelvis, sternum, vertebrae and clavicle.
What is the structure and function of sternum?
The Anatomy of the Sternum The sternum is a long, flat bone that protects the underlying muscles, organs, and important arteries within the chest. This includes the lungs, heart, and stomach, along with all of their intricate blood vessels, muscles, and cartilage.
What is the function of manubrium of sternum?
The manubrium is the most superior region of the sternum and articulates with the clavicles or collarbones and the first pair of ribs. The manubrium is the thickest portion of the sternum as it carries the greatest physical load.
Can you be born without a sternum?
CONGENITAL absence of the sternum, or a complete sternal cleft, is a rare chest wall malformation resulting from failed midline fusion during embryonic development. This abnormality can cause significant morbidity and, like other congenital anomalies, can have associated defects.
What organs are behind the sternum?
The thymus is a small organ located just behind the breast bone (sternum) in the front part of the chest….The thymus has 3 main layers:
- The medulla is the inside part of the thymus.
- The cortex is the layer that surrounds the medulla.
- The capsule is the thin covering over the outside of the thymus.
What is the sternum to the heart?
The sternum or breastbone is a long flat bone located in the central part of the chest. It connects to the ribs via cartilage and forms the front of the rib cage, thus helping to protect the heart, lungs, and major blood vessels from injury….

What are the 3 major functions of bone give examples of where we would see each?
What are the three main functions of the skeletal system?
- Mechanical. Support. Bones provide a framework for the attachment of muscles and other tissues.
- Protective. Bones such as the skull and rib cage protect vital organs from injury. Bones also protect the marrow.
- Metabolic. Mineral storage.
What is body of the sternum?
The body of the sternum (mesosternum) is the longest part of the sternum. It is flat with depressed ridges along the sides where the costal cartilages of the 3rd to 7th pairs of ribs articulate inferior to the sternal angle.[1] The sternal angle is where the body of the sternum joins the manubrium sterni.
Can you crack your sternum?
A sternum fracture, or break in the breastbone, is usually caused by direct trauma to the bone. The swelling of the joints associated with sternum fractures can cause popping in this area as well.
What type of functions does the sternum have?
The Anatomy of the Sternum Anatomy. The sternum as a whole has been compared to an upside-down sword due to the rectangular part at the top resembling a handle. Function. The sternum connects the first six ribs in the middle of the chest while serving as a strong protector of the stomach, heart, and lungs which lie below. Associated Conditions. Treatment.
What is the purpose for the sternum?
The main purpose of sternum is to protect the vital organs(heart,lungs and connecting blood vessels) from physical damage,As it connects to the ribs via cartilage forming the front of rib cage.
What are the 3 parts to the sternum?
Sternum. The ribcage protects the lungs, blood vessels, and heart, along with parts of the spleen, stomach, and kidneys from traumatic injury. 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.
What does the sternum articulate with?
The body of the sternum articulates above with the manubrium by means of a fibrocartilaginous joint (a symphis) called the manubriosternal joint, which allows slight movement between these two parts of the sternum when the ribs rise and fall during breathing.
