A rib; anything rib-like in shape; anything rib-like, as a ridge on shell, coral, insect-wing.

The ribs are 24 in number; 12 on each side. They irregular, long, bony curves: slightly flattened, and situate obliquely at the sides of the chest. The intervalas between them are called Intercostal spaces, (F.) Espaces intercostaux, and they are numbered first, second, third, &c., reckoning from above to below. They have been distinguished into Costae verae, Pleurapophyses of Owen, True ribs, (F.) Vraies cotes, Cotes sternales, Cotes vertebro-sternales (Ch.), and into Costae spuriae, Mendosae seu Nothae Costae, False ribs, Cotes asternales (Ch.), Fausses Cotes. The true or sternal ribs, as they have also been called, are the first 7; which are articulated at one extremity to the spine, and at the other, by means of their cartilages, haemapophyses of Owen, to the sternum. The false or short ribs are the remaining 5: the uppermost three being united, by means of their cartilages, to the cartilage of the last true rib. The others are free at their external extremity, and, hence, have been called Floating ribs, Costae fluctuantes, (F.) Cotes flottantes. The vertebral extremity of each rib is slightly expanded. It is called the head of the rib- Capitulum Costae: the space between this and the tubercle is the collum or neck. Anterior to the tubercle is the angle- Angulus seu Cubitus Costae. The angle is the part where the bone bends to form the lateral part of the thorax.
