Similar to how the first seven ribs articulate with the sternum, the cartilage within the celiac plexus attaches to the xiphoid process, reinforcing it, and indirectly connecting the costal cartilage to the sternum. The xiphoid process plays a role in the attachment of many muscles, including the abdominal diaphragm, a muscle necessary for ...
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. Shaped roughly like a necktie, it is one of the largest and longest flat bones of the body. Its three regions are the manubrium, the body, and the xiphoid process. [1]
The costoxiphoid ligaments (chondroxiphoid ligaments) are inconstant strand-like fibrous bands that connect the anterior and posterior surfaces of the seventh costal cartilage, and sometimes those of the sixth, to the front and back of the xiphoid process the sternum.
The muscle extends from the pubic symphysis, pubic crest and pubic tubercle inferiorly, to the xiphoid process and costal cartilages of the 5th–7th ribs superiorly. [ 1 ] [ 2 ] The rectus abdominis muscle is contained in the rectus sheath , which consists of the aponeuroses of the lateral abdominal muscles.
The rib cage or thoracic cage is an endoskeletal enclosure in the thorax of most vertebrates that comprises the ribs, vertebral column and sternum, which protect the vital organs of the thoracic cavity, such as the heart, lungs and great vessels and support the shoulder girdle to form the core part of the axial skeleton.
An X-ray of a human chest area, with some structures labeled. The contents of the thorax include the heart and lungs (and the thymus gland); the major and minor pectoral muscles, trapezius muscles, and neck muscle; and internal structures such as the diaphragm, the esophagus, the trachea, and a part of the sternum known as the xiphoid process.
The sternal angle marks the point at which the costal cartilage of either second rib articulates with the sternum. During physical examinations, the readily palpated sternal angle is thus used as a landmark to identify the 2nd rib, and by extension, by counting, also the remaining ribs. Meanwhile, the first rib cannot be used for this purpose ...
The costal margin is the medial margin formed by the cartilages of the seventh to tenth ribs. It attaches to the body and xiphoid process of the sternum. [2] The thoracic diaphragm attaches to the costal margin. [3] The costal angle is the angle between the left and right costal margins where they join the sternum. [2]
