In old age, the costal cartilages are prone to superficial ossification, particularly in women with age of 50 years and over. [3] In costochondritis and Tietze syndrome, inflammation of the costal cartilage occurs. [4] This is a common cause of chest pain. [5] Severe trauma may lead to fracture of the costal cartilage. [6]
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]
Costal may refer to: an adjective related to the rib (Latin: costa) in anatomy Costal cartilage, a type of cartilage forming bars which serve to prolong the ribs forward; Costal margin, the medial margin formed by the false ribs; Costal surface (disambiguation) Costal groove, a groove between the ridge of the internal surface of the rib
The sternocostal joints, also known as sternochondral joints or costosternal articulations, are synovial plane joints of the costal cartilages of the true ribs with the sternum. [1] The only exception is the first rib , which has a synchondrosis joint since the cartilage is directly united with the sternum. [ 1 ]
The first rib is attached to thoracic vertebra 1 (T1). At the front of the body, most of the ribs are joined by costal cartilage to the sternum. Ribs connect to vertebrae at the costovertebral joints. [4] The parts of a rib includes the head, neck, body (or shaft), tubercle, and angle. The head of the rib lies next to a vertebra. The ribs ...
Joints between costal cartilages of the sixth and ninth rib are plane synovial joints. Articulation between costal cartilage of the ninth rib and tenth rib is fibrous. [1] The lateral end of each costal cartilage is received into a depression in the sternal end of the rib, and the two are held together by the periosteum.
In other words, the word refers to the area of the ventral trunk that is located below the costal cartilages. [4] The word once referred only to the soft portion of the abdomen between the rib cage and the navel (the region once believed to be the seat of hypochondriasis ), but it is not used that way in modern anatomy's schemes for the regions ...
A facet on each side of the thoracic vertebral body articulates with the head of the rib. The transverse process of a lumbar vertebra is also sometimes called the costal [9] [10] or costiform process [11] because it corresponds to a rudimentary rib (costa) which, as opposed to the thorax, is not developed in the lumbar region.
