Rib {rib) [ME., rib, rib]. I. In anatomy, a rib is a 

 long, flat, curved bone, with an ectal and an ental broad 

 smooth surface, cephalic rounded border, and a caudal 

 sharp one. Within the greater part of the length of the 

 lower border there exists a groove for the intercostal 

 blood-vessels. The dorsal end is the head, and 

 this presents two articular facets (separated by 

 the intervertebral ridge) which articulate with corre- 

 sponding facets of a contiguous pair of vertebrae . Slightly 

 ventral, just beyond a slight constriction, the neck, 

 is the tubercle, upon which is a facet for articulation 

 with the transverse process of the lower of the two

vertebrae united by the head of the rib. Externally to 

 the tubercle is a rough mark called the angle, at which 

 point the rib is directed abruptly ventrad. The 

 ventral portion is more compressed and is continuous 

 with the costal cartilage. The ribs successively in- 

 crease in length from the first to the eighth and then 

 decrease to the last. They number twelve pairs, form- 

 ing a series of narrow arches on each side of the trunk 

 extending from the thoracic vertebrae to the sternum. 

 The seven superior or sternal ribs are attached to both 

 the spine and the sternum. The remaining five are 

 called asternal ribs. Three of these are attached 

 dorsally to the spine, and ventrally by costal carti- 

 lages to the cartilages of adjacent ribs. The two 

 last are free at their anterior extremities, and are 

 called free ribs. 2. A primary or principal vein of a
