The internal maxillary artery ( a.) (r. maxillaris interims) is largerthan the temporal. From the multiplicity ARTERIES. (Special Anat.) of its branches and their complicated dis-tribution, it is difficult to render them in-telligible by mere description. It sepa-rates from the temporal in the substanceof the parotid gland, and on a level withthe neck of the condyle of the lower jawIn its course forwards to the deep-seatedparts of the face which it supplies, it is Fig. o.

Tracing it from itsorigin from the external carotid, or ratherfrom the point at which it separates fromthe temporal, it may be divided into threeportions, founded upon the direction pur-sued by it. 1. It advances downwards and inwards tosweep round the inner surface of the neckof the condyle of the lower jaw, and be-tween it and the internal lateral ligament;—then inwards between the two pterygoidmuscles, and the inferior dental and thelingual nerves, and here changing its direc-tion again, it advances forwards towardsthe tuber of the superior maxillary bone,where it terminates in the second, or ver-tical portion. The course of this first partof the artery is nearly horizontal. 2. Having reached the pterygoid pro-cess, the internal maxillary artery ascendsin nearly a perpendicular direction, be-tween the attac
