Fig. 7. Alligator mississippiensis (LDWF 904625, Recent). Coronal T2 weighted fast spin echo MRI of showing branches of the trigeminal nerve. The images progress from caudal to rostral. A. The caudalmost slice shows the trigeminal ganglion and the large mandibular branch (V3) entering the jaw muscle complex. B. Proximal maxillary branch (V2) exiting skull at apex of pterygoid space while the proximal ophthalmic branch (V1) travels towards the orbit inside the skull. C. V1 in the roof of the cavernous sinus, V2 outside the skull and prior to entering the posterior orbital floor next to the recurrent loop of the internal carotid artery. This section of the carotid artery is proximal to the anterior and posterior encephalic arteries (Burda 1969). D. V2 traversing the floor of the orbit before entering the snout. All sections are in the same scale.
