In this path, the lateral costal branch establishes anastomosis with the posterior and anterior intercostal arteries of the first to eighth intercostal spaces through two fine branches, generating an intermediate longitudinal vascular axis for these arteries, as well as emitting direct branches for the thoracic wall, forming part of the arterial circuit of this wall.
In contrast to mammals with a circular thorax (primates), in mammals with a major ventrodorsal axis (quadrupeds) the internal intercostal artery runs obliquely after crossing the first rib and emits a branch that runs ventrally in parallel to the sternal border and that supplements the anterior intercostal arteries.
