1 This term, costotransvme foramen, is also used by English anatomists to denote the foramina in the 

 transverse processes of the cervical vertebrae for the transmission of the vertebral artery. TR. 



- These are upper and lower costal facets respectively in relation to the articular surface of the head of the 

 rib : but, strictly speaking, what is here called " upper costal facet " is the lower costal facet of the sixth dorsal 

 vertebra; while what is here called "lower costal facet" is the upper costal facet of the seventh dorsal 

 vertebra. TR. 



FIG. 409. COSTOCENTRAL AND COSTOTRANSVERSE ARTICULATIONS : ANTERIOR COSTOCENTRAL OR 

 STELLATE LIGAMENT; INTERARTICULAR COSTOCENTRAL LIGAMENT; ANTERIOR SUPERIOR 

 COSTOTRANSVERSE LIGAMENT; AND COSTOTRANSVERSE FORAMINA. POSTERIOR OR INTERNAL 

 INTERCOSTAL APONEUROSES. (THE THIRD TO THE SEVENTH DORSAL VERTEBRAE WITH THE 

 VERTEBRAL EXTREMITIES OF THE THIRD TO THE SEVENTH RIGHT RIBS ; SEEN FROM THE 

 RIGHT AND FROM BEFORE.) 



The third, fourth, and fifth costocentral articulations are unopened ; the sixth and the seventh have 

 been opened from before. In the sixth articulation, by the partial removal of the bodies of the 

 fifth and sixth dorsal vertebras, the upper and lower surfaces of the intervertebral disc have been 

 exposed, and the attachment of the disc to the rid^e between the two articular facets on the head 

 of the rib has been demonstrated.
