Regarding this illustration by Quain, Fisher quoted Quain on the absence of the left internal carotid as follows: ". . .the carotid artery furnishes the usual branches of the external carotid and divides into temporal and internal maxillary arteries. In the place of an internal carotid, of which there is no trace, two tortuous branches derived from the internal maxillary join within the skull to form a single vessel which lies to the inner side of the fifth nerve. The artery so constructed being, however, smaller than the usual size of the internal carotid, the deficiency is compensated by the artery of the opposite side, which is of large size."
From Fisher, A.G.T. A case of complete absence of both internal carotid arteries, with a preliminary note on the developmental history of the stapedial artery. J. Anat. Physiol. 48:37-46, 1914.
