External carotid nerve: The nerve was approximately 3032 mm in length and 3-4 mm in width at its beginning which emerged from the rostroventral margin of the CCG as a single nerve, ran little rostral to the internal carotid artery and medial to the ascending pharyngeal artery to their origin from the common carotid artery.
The following vascular and visceral branches were detached from the external carotid nerve:
Occipital branch: One or two thin large branches emerged from the external carotid nerve and reached the occipital artery at the level of its origin from the common carotid artery.
Carotid sinus branch: Small branches derived from the terminal part of the external carotid nerve to the vicinity of the origin of the internal carotid and occipital arteries from the dorsal surface of the common carotid as a carotid sinus.
Ascending pharyngeal branch: The vascular branches to the origin of the ascending pharyngeal artery derived from the medial surface of the external carotid nerve or from the ascending pharyngeal artery.
Linguofacial branch: The nerve branch was one of the most distinct vascular nerve branches of external carotid nerve as a direct vetro rostral continuation of the external carotid nerve along the dorsomedial surface of the artery (Figs.
Glandular branch: Two short branches were direct downward continuation of the external carotid nerve to the dorsal end of the mandibular salivary gland, lying on the course of the medial surface of the common carotid artery near its transition to the external carotid artery (Fig.
External carotid nerve. In this study, the external carotid nerve was composed of a single branch emerging from the rostroventral margin of the CCG.
The external carotid nerve emerged from the lateral and ventral of the cranial part of the CGG in some roe deer or from the lateral and ventral of the caudal part of the CGG in most roe deer, or from the rostroventral and caudolateral aspects of the CCG in the Bactrian camel, or from the caudoventral and caudomedial aspect of the CCG in the pig (Kabak et al.), or from the caudal half of the CCG in the Angora goat, or from the caudoventral and caudolateral aspects of the CCG in the white yak, yak, or from the rostroventral margin of the CCG in the donkey, or from the mediorostral surface of the CCG in most roe deer, or from the medial surface of the rostral half of the CCG in some roe deer.
The point of division of the external carotid nerve exhibited significant differences among species.
The distribution of the external carotid nerve in the bovine was remarkably different from that of the reported ungulates species.
In the literature, the carotid sinus branch of the CCG was demonstrated as one branch of the external carotid nerve detaching from the caudoventral margin of the CCG in the Bactrian camel, yak, white yak, and roe deer.
