CIRCUIT COSTAE Meaning and
Definition
-
Circuit costae is a Latin term used in anatomy referring to the ribs, specifically denoting the twelve pairs of bones that extend from the thoracic vertebrae in the vertebral column and curve around the chest cavity. These curved bones form an important part of the ribcage, playing a crucial role in protecting the heart, lungs, and other vital organs within the thoracic cavity.
Each pair of circuit costae is connected to the thoracic vertebrae at the back of the body and meets in the front at the sternum, through either direct attachment or indirect attachment via cartilage. The upper seven pairs of circuit costae are known as "true ribs" as they are directly connected to the sternum through costal cartilages, while the remaining five pairs are called "false ribs" due to their indirect attachments.
The circuit costae provide structural support to the thoracic cage, contributing to the overall stability of the thorax. Furthermore, they allow for movement and flexibility during respiration, facilitating the expansion and contraction of the chest cavity to assist in breathing. The circuit costae also serve as points of attachment for various muscles involved in respiration, such as the intercostal muscles and the diaphragm.
In summary, circuit costae are the twelve pairs of curved bones known as ribs that enclose and protect the chest cavity, facilitate respiration, and provide structural support to the thorax.
