3. Carotid Arteries of Ruminants, 



A. In the Sheep, which will serve as a type for this description, the carotid ait 

 arise by a common trunk from the right axillary artery, as in Solipcds. Arming in tin- 

 cephalic region, towards the upper part of the neck, they furnish a tlninril and a 

 laryngeal branch, then give off a very slender occipital artery, nnd an- continued from this 

 point by the external carotid. 



The internal carotid, properly called, is absent, and we will see immediately how it id 

 compensated for. 



Oeaipital art< ry. Having given some ramuscules to the anterior recti muscles of the 

 head, and a small mcningeal branch which enters the cranium by the po.-teiior IM< 

 foramen, this vessel passes into the condyloid foramen, which also affords a pas> 

 the hypoglossal nerve, places itself beneath the dura mater, and is inflected backward to 

 (-IM-II into the anterior extremity of the collateral artery of the spine, at the superior 

 foramen of the atlas. The branch resulting from this junction emerges by that foimucn, 

 to l.c distributed in the muscles of the neck, where its divisions resemble th.-e of the 

 occipito-mtiscular and iitloido-muscular branches in the Horse. 



In traversing tne condyloid foramen, the occipital artery sends into the pai 

 temporal canal, by a peculiar bony conduit (sec pago 56), a very small filament which 

 is distributed to the dura mater, in anastomosing with a branch of the posterior auricular. 



It communic;it; s, after its entrance into the cranial cavity, with the ,v-v, <m <<./// 



Kxb rnal enmliil itflinj. Terminated, as in the Horse, by the *",/;//<// t, i,i/ <.// and 

 inti fiinl nmsilltiri/ arteries, this vessel sends off on its course : 



1. A pliaryngeal artery, whose origin is nearly confounded with that of the occipital 

 artery. 



2. The lingual artery, furnishing a collateial branch which exactly repre^'iils th" 

 submental of Man, and is divided into two branches, which resemble the ntblingual ami 

 ranine arteries. 



3. A large division for the maxillary gland. 



4. The posterior auricular artery, from which proceeds: 1, The ftiilu-iit<ifli>:il t\vi^. 

 which penetrates the aqueduct of Fallopius; 2, Concho-mugcular branches; 3, A larirc 

 branch, resembling the mastoid artery of the Horse. This enters the temnoro- parietal 

 canal by a small foramen between the occipital and petrous jx>rtion of tlie temporal 

 bone, and forms two branches: an external, emerging from this cannl by the wide 

 orifice in the temporal fossa, and expending itself in the temporal muscle, after anas- 

 tomosing with the two deep temporal arteries ; and an internal, a considerable 

 meningcal artery, destined principally to the falx cerebri and the tentorium cerebelli. 



5. A small maxilla-muscular artery, ramifying entirely in the internal ptoryguid and 

 the Mibcutum ous muscles. 



Superficial temporal artery. This .vessel divides, almost at its origin, into three 

 branches : 



1. A posterior, supplying the anterior arteries of the ear. 



2. An anterior, forming the transversal faciei, and terminating by the coronary or 

 labial arteries, after giving some ramuscules to the massetcr and the muscles of the 

 forehead. 



3. A median artery, representing the middle temporal of Man. This vessel detaches 

 some divisions to the temporal muscle, ej v ,. s oil' the lai-hrynml tirtn-ij, as wt 11 as a 

 palpebral branch rising from the mine jmint, and terminates near the l.asc of the crnninm 

 by two particular arteries which a e developed around the base of tlie horn, and form a 

 real arterial circle from which inferior and superior divisions are given off. The hitter 

 are the mo,t con.-iderable, and glide on the Ixmy core of the frontal appendage, where 

 they are distributed almost exclusively to the gem-rating membrane of the horny tissue, 

 only throwing KOIPC filaments into the sinuses.
