Human breast bone-Chest Bones Diagram & Function | Body Maps

The bones of the chest — namely the rib cage and spine — protect vital organs from injury, and also provide structural support for the body. Flexible yet strong, the rib cage protects major vital organs such as the heart, lungs, and liver. Contrary to urban legend and some religious beliefs, women do not have more ribs than men. A typical rib cage has 24 ribs. Each rib extends from the spinal cord and wraps around the body in a semicircle.

  • The normal developmental program that prolactin generates in the mammary gland is usurped in the cancerous process and can be used out of its normal cellular context at a site of secondary metastasis.
  • The sternum or breastbone is a long flat bone located in the central part of the chest.
  • The sternum, or breastbone , is a flat bone at the front center of the chest.
  • The sternum, commonly known as the breastbone, is a long, narrow flat bone that serves as the keystone of the rib cage and stabilizes the thoracic skeleton.

The bones of the chest — namely the rib cage and spine — protect vital organs from injury, and also provide structural support for the body. Flexible yet strong, the rib cage protects major vital organs such as the heart, lungs, and liver.

Contrary to urban legend and some religious beliefs, women do not have more ribs than men. A typical rib cage has 24 ribs. Each rib extends from the spinal cord and wraps around the body in a semicircle.

The ribs encircle vital organs, such as the lungs, and connect to the costal cartilage in the front of the body. This hard cartilage extends from the end of each rib and connects to the sternum. However, the bottom three ribs do not connect to the costal cartilage. This allows humans to bend at the waist without the ribs interfering with the pelvis. 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. The clavicle, or collarbone , extends across the front of the shoulder from the sternum to the scapula, or shoulder blade. It is frequently fractured in automobile accidents and sports injuries. The scapula, or shoulder blade , is a flat triangular bone located in the back of the shoulder.

It connects with the collarbone in the front of the body. It is also is connected to the shoulder joint, which brings together the shoulder blade and the humerus , or the large bone of the upper arm.

The spine , or vertebral column, is a very important part of the human body. Running from the brain to the tailbone, the spine is a nerve center enclosed in a series of 24 connected bones called vertebrae.

Each bone is cushioned with a disc made of cartilage that acts as a joint and ligament to keep the vertebrae connected. As women age, they typically lose bone density to osteoporosis , a progressive bone disease.

This loss leaves them weak and susceptible to traumatic fractures. Supplements and medications are typically given to help bones retain their mass. Osteoporosis primarily affects women over the age of 50 because women typically tend to lose about 1 percent of their bone mass after the age Postmenopausal women are at a greater risk because the hormone estrogen, which declines after menopause, aids in bone density.

The manubrium is the widest and most superior region of the sternum. It forms joints with the clavicles and the first and second pairs of ribs through their costal cartilages. The clavicles meet the manubrium at the concave clavicular notches to form the sternoclavicular joint, the only point of skeletal attachment between the pectoral girdle of the shoulder and the axial skeleton of the thorax.

Slight indentations on the lateral sides of the manubrium provide attachment points for the costal cartilages of the ribs. At its inferior end, the manubrium meets the body of the sternum at the joint with the costal cartilage of the second ribs. Here it forms the sternal angle, a slight posterior bend in the sternum that can be felt through the skin and serves as an important anatomical landmark in the medical profession. Several important muscles attach via tendons to the manubrium, including the sternocleidomastoid, pectoralis major, sternohyoid, and sternothyroid muscles.

The body of the sternum is the longest region of the sternum and is roughly rectangular in shape. 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. In addition, the powerful pectoralis major muscles that adduct and flex the humerus at the shoulder attach to the anterior surface of the body of the sternum and manubrium. The smallest and most inferior region of the sternum, the xiphoid process, begins life as a region of flexible hyaline cartilage attached to the end of the body of the sternum.

The xiphoid process slowly ossifies throughout childhood and adulthood until around age 40 when all of its cartilage is replaced by bone. Regardless of its degree of ossification, the xiphoid process serves as an important attachment point for the tendons of the diaphragm, rectus abdominis, and transverse abdominis muscles. Rib pairs eight through ten are called 'false ribs' because instead of being directly connected to the sternum, they are connected to the seventh rib.

A broken sternum is a break in the breastbone, the long, flat bone that's located in the center of the chest and connected to the ribs via cartilage. When you hear your sternum "popping," you're hearing the sternocostal and costochondral joints "click" or "pop.

Sternum pain: Causes and when to see a doctor

As part of the bony thoracic wall, the sternum helps protect the internal thoracic viscera — such as the heart, lungs and oesophagus.

In this article, we shall look at the osteology of the sternum — its constituent parts, articulations, and clinical correlations. The sternum can be divided into three parts; the manubrium , body and xiphoid process. In children, these elements are joined by cartilage.

The cartilage ossifies to bone during adulthood. The manubrium is the most superior portion of the sternum. It is trapezoid in shape. The superior aspect of the manubrium is concave, producing a depression known as the jugular notch — this is visible underneath the skin.

Either side of the jugular notch, there is a large fossa lined with cartilage. These fossae articulate with the medial ends of the clavicles, forming the sternoclavicular joints. Inferiorly, the manubrium articulates with the body of the sternum, forming the sternal angle.

This can be felt as a transverse ridge of bone on the anterior aspect of the sternum. The sternal angle is commonly used as an aid to count ribs, as it marks the level of the 2nd costal cartilage. The body is flat and elongated — the largest part of the sternum. It articulates with the manubrium superiorly manubriosternal joint and the xiphoid process inferiorly xiphisternal joint. The lateral edges of the body are marked by numerous articular facets cartilage lined depressions in the bone.

These articular facets articulate with the costal cartilages of ribs There are smaller facets for articulation with parts of the second and seventh ribs — known as demifacets. The xiphoid process is the most inferior and smallest part of the sternum. It is variable is shape and size, with its tip located at the level of the T10 vertebrae.

The xiphoid process is largely cartilaginous in structure, and completely ossifies late in life — around the age of In some individuals, the xiphoid process articulates with part of the costal cartilage of the seventh rib.

Sternal fractures are associated with severe blunt trauma to the chest, such as in a vehicular accident. They are relatively uncommon. Typically, the sternum will break into several pieces — this type of fracture is classified as a comminuted fracture. The most common site of fracture is the manubriosternal joint — where the manubrium meets the body of the sternum. Despite the degree of damage to the sternum, the fragments are not usually displaced due to the attachment of the pectoralis muscles.

This is not due to the fracture itself, but usually as a result of heart and lung injuries, which are likely to occur simultaneously with the primary trauma.

Because of this, it is crucial to check patients with sternal fractures for visceral injury. X-ray, CT and ultrasound are common investigations. Once you've finished editing, click 'Submit for Review', and your changes will be reviewed by our team before publishing on the site.
