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 ...
A fully grown adult features 26 bones in the spine, whereas a child can have 33. Cervical vertebrae (7 bones) Thoracic vertebrae (12 bones) Lumbar vertebrae (5 bones) Sacrum (5 bones at birth, fused into one after adolescence) Coccyx (set of 4 bones at birth)
Skeletons of a human and an elephant. Comparative foot morphology involves comparing the form of distal limb structures of a variety of terrestrial vertebrates.Understanding the role that the foot plays for each type of organism must take account of the differences in body type, foot shape, arrangement of structures, loading conditions and other variables.
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.
Human anatomy is the scientific study of the morphology of the adult human. It is subdivided into gross anatomy and microscopic anatomy . Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by unaided vision.
Costochondritis is a common condition that is responsible for approximately 13–36% of acute chest pain-related concerns from adults depending on the setting, with 14–39% for adolescents. [8] It is most often seen in individuals who are older than 40 years of age and occurs more often in women than in men.
Meckel's cartilage is a piece of cartilage from which the mandibles (lower jaws) of vertebrates evolved. Originally it was the lower of two cartilages which supported the first branchial arch in early fish. Then it grew longer and stronger, and acquired muscles capable of closing the developing jaw. [1]
