In short, the scapular portion is displaced, the sternal is nearly in situ; though, from the depression of the former, the prominence of the latter appears to arise from displacement.
The wound is generally small, and occasioned by the projection of the sternal portion; or the integument may be divided by the external force.

In the young Cirripede, after the metamorphosis, there is no trace of this medial dorsal suture, or of the wider sternal surface.
Moreover, in all Cirripedes there is another striking peculiarity connected with these parts, namely, the exclusive attachment of the whole thorax or included body to the internal ventral or sternal surface of the carapace and head.
Thus the sternum, or rather the complex of sternal elements, is defined and discovered in particular cases not by its connections only but also by its functions.
If these are sternal ribs, the bones to which they are attached must be the hyo- and hyposternals or "annexes," the bones from which in birds the ribs take their origin.
The unpaired sternal bone (urohyal) cannot be homologous with the entosternal, for it has no connections with the annexes.
So, too, in dealing with the homologies of the sternal elements (supra, p.
Geoffroy's next step is to point out that the only possible homologues of sternal ribs are the branchiostegal rays, which arise from the large bones of the hyoid arch.
In the other air-breathing Vertebrates the nine sternal elements can according to Geoffroy be discovered without great difficulty.
Its tergal plate is usually retained, but its sternal plate is generally suppressed.
In the case of the somites bearing the walking legs the tergal and sternal elements are preserved without fusion with the corresponding plates of the preceding or succeeding somites, so that great flexibility of the body is retained.

Von Meyer has described the first pair of ribs as frequently larger than the others, and there appear in Rhamphorhynchus to be examples preserved of the sternal ribs, which connect the dorsal ribs with the sternum.
The bone cannot be entirely attributed to the effect of flight, since there is no such expanded sternal shield in Bats.
Crocodiles have the bone more elongated, so that it has somewhat the aspect of a very strong first sternal rib when seen on the ventral face of the animal.
The small number of sternal ribs is even more characteristic of birds than mammals or reptiles.
In Crocodiles it is a cartilage to which the sternal ribs unite; and upon its front portion a flat knife-like bone called the interclavicle is placed.
