They form when the pars sternalis
and a costochondral arch fuse and close around the internal thoracic artery as it becomes the superior epigastric artery.
These specimens are referred to Branta rather than to Anser (including Chen) because of these characters: coracoid - medial half of Facies articularis sternalis more excavated (concave); ulna - Tuberculum carpale wider, less excavated on ventral surface; radius - similar placement and development of intermuscular lines; tibiotarsus - general agreement in size and overall morphology.
We refer these specimens to the extinct tadornine genus Anabernicula rather than to Anas because of these characters: coracoid - Sulcus musculo supracoracoidei deep, Cotyla scapularis deep, Processus procoracoideus rugose in dorsal aspect with subparallel lineations, Facies articularis sternalis deep and distinct in dorsal aspect; tibiotarsus - Condylus medialis narrow; in distal aspect, intercondylar region relatively shallow.
From Australia Debra Meerkotter describes the importance of the sternalis
muscle, which is a normal anatomical variant seen in mammography.
1P), with intercoxal sclerites, and/or with the carapace; PME = posterior median eyes; PSP = plagula sternalis
postica - the plagula is a triangular or ribbon-shaped sclerite situated on the ventral side of the petiolus - it may be fused with the sternum (Simon 1892:5, figs.
This is the first description of the sternalis
muscle being found among the cadavers used during the last two decades in the dissection laboratories of the San Juan Bautista School of Medicine.

As mammographic techniques improve, more attention is being given to imaging the medial breast, and the sternalis
muscle will be revealed with increasing frequency.
