Anatomy the rib cage is a bony structure found in the chest thoracic cavity. Generally there are twelve pairs of ribs. What kind of joints are costovertebral and costaotransverse joints.

By the costovertebral joint. The typical rib consists of a head neck and body. The head is wedge shaped and has two articular facets separated by a wedge of bone.

But for an anatomy study its not. There are 11 pairs of external intercostal muscles. There are two classifications of ribs atypical and typical.

This muscle assists in depression of the ribs. The ribs are the bony framework of the thoracic cavity. It is made up of 12 pairs of ribs.

For a gesture drawing thats good enough. Although fixed into place these ribs do allow for some outward movement and this helps stabilize the chest during inhalation and exhalation. They run inferoanteriorly from the rib above to the rib below and are continuous with the external oblique of the abdomen.

The rib cage is often simplified as an oval shape. Originate at the lower border of the rib inserting into the superior border of the rib below. It has clear front side and back planes.

Each pair is numbered based on their attachment to the sternum a bony process at the front of the rib cage which serves as an anchor point. Elevates the ribs increasing the thoracic volume. Facets for tubercles of like numbered ribs on its transverse processes.

Articular facets for the heads of ribs on posterolateral aspects of the body. The transversus thoracic muscles originate from the posterior surface of the xiphoid process and the lower part of the body of the sternum. The fibres pass superolaterally to insert into the costal cartilages of ribs three to six.

The rib cage is more like an egg because the top is narrower than the bottom. Related posts of muscle anatomy rib cage muscle anatomy interactive. At the chest many rib bones connect to the sternum via costal cartilage segments of hyaline cartilage that allow the rib cage to expand during respiration.

Each rib articulates posteriorly with two thoracic vertebrae. Flashcard anatomy of the ribs. An exception to this rule is that the first rib articulates with the first thoracic vertebra only.
