Examples of costal in the following topics:

    • Due to its flat nature, the scapula presents two surfaces and three borders; the front-facing costal surface and the rear-facing dorsal surface, as well as the superior, lateral, and medial borders.
    • The serratus anterior originates from the costal surface, which also provides an attachment for the subscapularis muscle.
    • Costal surface of the left scapula.

  • Thoracic Cage: Sternum

    • Located below the manubrium, the gladiolus is the longest portion of the sternum and articulates with the ribs, either directly or indirectly, through the costal cartilage
    • The thin, pointed xiphoid process forms the most inferior region of the sternum to which the costal cartilage and cartilage of the celiac, or solar, plexus attaches.

  • Thoracic Cage: Ribs

    • The first five ribs are termed true ribs because they attach directly to the sternum through the costal cartilage.
    • The next five ribs are termed false ribs because they attach to the sternum indirectly through the costal cartilage.

  • Ascending Aorta

    • The ascending aorta is a portion of the aorta beginning at the upper part of the base of the left ventricle, on a level with the lower border of the third costal cartilage behind the left half of the sternum; it passes diagonally upward, forward, and to the right, in the direction of the heart's axis, as high as the upper border of the second right costal cartilage.

  • Overview of the Axial Skeleton

    • A typical human rib cage consists of 24 ribs, the sternum, costal cartilages, and the 12 thoracic vertebrae .

  • Cartilaginous Joints: Synchodroses

    • In this example, the rib articulates with the sternum via the costal cartilage.

  • Rhinoplasty

    • The autologous grafts usually are harvested from the nasal septum, but, if it has insufficient cartilage (as can occur in a revision rhinoplasty), then either a costal cartilage graft (from the rib cage) or an auricular cartilage graft (concha from the ear) is harvested from the patient's body.

  • Types of Connective Tissue

    • It is a major part of the embryonic skeleton, the costal cartilages of the ribs, and the cartilage of the nose, trachea, and larynx.

  • The Axial Skeleton

    • The first seven pairs of ribs attach to the sternum with costal cartilage and are known as true ribs.
