It is doubtful whether the buccal nerve partially terminates in the orbicularis oris, the triangularis oris, and the zygomaticus major. All the filaments which enter these mus- cles, and which appear at first sight to terminate in their substance, pass through them to supply the mucous membrane ; their branches anastomose with the mental nerve be- neath the triangularis oris ; several filaments are lost in the buccinator.

The Internal Pterygoid Nerve. The internal collateral branch {t, fig. 299), or nerve for the internal pterygoid muscle, which is very slender, comes off from the inner side of the inferior maxillary nerve in contact with a grayish body, named the otic ganglion, runs downward and inward along the inner surface of the internal pterygoid muscle, and ramifies in it. The Auriculo-temporal Nerve. The posterior collateral branch, or the auriculo-temporal nerve (the auricular or superfir cial temporal nerve of authors), is very large, flattened, and plexiform at its origin (be- hind c, fig. 298 ; r, fig. 299); it sometimes arises by a great number of distinct roots ; it passes backward and a little downward behind the neck of the condyle of the lower jaw, and divides into two branches, a superior or ascending, and an inferior or dcscendiitg branch. The superior or ascending branch, the superficial temporal nerve, turns round the back of the neck of the condyle, and ascends vertically between the articulation and the ex- ternal auditory meatus; having become sub-cutaneous, it divides into several filaments (r, fig 285), which may be traced up to the highest part of the temporal fassa. During its course this nerve gives off a very remarkable anastomotic branch, which arises behind the neck of the condyle, and is reflected upon it so as to run forward be- neath the facial nerve, with which it is ble
