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 ...
The costal cartilage of the second rib articulates with the sternum at the sternal angle making it easy to locate. [3] The transversus thoracis muscle is innervated by one of the intercostal nerves and superiorly attaches at the posterior surface of the lower sternum. Its inferior attachment is the internal surface of costal cartilages two ...
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 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.
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 muscle which can 'cancel' or to some degree reverse the action of the muscle. Muscle synergies are noted in parentheses when relevant. O (Occurrences) Number of times that the named muscle row occurs in a standard human body. Here it may also be denoted when a given muscles only occurs in a male or a female body.
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.
The transversus thoracis muscle (/ t r æ n z ˈ v ɜːr s ə s θ ə ˈ r eɪ s ɪ s /), also known as triangularis sterni, lies internal to the thoracic cage, anteriorly.It is usually a thin plane of muscular and tendinous fibers, however on athletic individuals it can be a thick 'slab of meat', situated upon the inner surface of the front wall of the chest.
