“…In these species, the TG receives its blood supply directly from a branch or branches of the internal carotid artery [Bergmann, 1942;Lasjaunias et al, 1977;Okuda. 1979;Ohtsuki, 1984;Krisht et al. 1994], which do not exist in the tree shrew.…”

“…In humans, the stapedial artery is underdeveloped and disappears be fore birth [Diamond. 19871 or at the end of the first tri mester [Lauritzen et al, 1988], It is quite interesting that the blood supply to the TG in the tree shrew and in the monkey is mainly via the ex tracranial and intracranial routes [Ohtsuki, 1984], while in the dog only via the extracranial route [Okuda. 1979].…”

“…They are the petrosal branch, the anastomotic ramus, the anastomotic artery, the middle meningeal artery, the accessory meningeal artery, and the internal carotid artery [Okuda. 1979], In the monkey, however, the gan glionic blood supply is via the internal carotid artery, the accessory meningeal artery and from the basilar artery [Ohtsuki, 1984], Since the three-dimensional intraganglionic vascular distribution of TG has not yet been well elucidated, it is of interest to apply the vascular cast/SEM technique to study the TG in the tree shrew, an animal which is still subject to the controversy on whether it should be classified as a primitive primate [Walker et al, 1964;Valen, 1965;Lekagul and McNeely, 1977;Pally, 1984] or an insectivore [Gregory. 1910;Hill.…”

Since there is only a limited number of studies of the blood supply to the trigeminal ganglion (TG) in mammalian species, the TG from 16 common tree shrews (Tupαiα glis) were investigated by light microscope, transmission electron microscope (TEM) and the corrosion cast technique in conjunction with scanning electron microscope (SEM). It was found that the TG contained clusters of neurons in the peripheral region whereas the bundles of nerve fibers were located more centrally. Each ganglionic neuron had a concentric nucleus and was en-sheathed by satellite cells. It was noted that blood vessels of a continuous type were predominantly found in the area where the neurons were densely located and were much less frequently observed in the area occupied by nerve fibers. With TEM, the TG was shown to be mainly associated with large neurons containing big nuclei and prominent nucleoli. The blood supply of the TG is derived from the most rostral branch of the pontine artery, from the stapedial artery or sometimes from the supraorbital artery, and from the accessory meningeal artery which is a branch of the maxillary artery passing through the foramen ovale. These arteries give off branches and become capillary networks in the ganglion before draining blood to the peripheral region. The veins at the medial border drained into the cavernous sinus directly or through the inferior hypophyseal vein, while those at the lateral side of the ganglion carried the blood into the pterygoid plexus via an accessory meningeal vein. The veins along the trigeminal nerve root joined the posterior part of the cavernous sinus. These studies establish a unique anatomical distribution of the TG blood supply in the tree shrew and the utility of the cast/SEM technique in discerning detailed features of the blood supply in the nervous system.

Abstract:The blood supply of the trigeminal ganglion in the Macaca irus and dog was summarized by surveying many vascular specimens utilizing the acryl plastic injection method. On the basis of the findings obtained,the present study was made and discussed whether the external or internal carotid system might play a principal route as the supply source for the ganglion in the respective species.The ganglion of the Macaca irus was situated on the anterior surface of the temporal petrosa being close to the brain site,but in the dog on the base of the greater ala of the sphenoid bone at a short distance from the brain site.The main source of the ganglionic branches in the Macaca irus can be said to be the internal carotid(such as the marginal and basal tentotrial, the anterior petrosal and the trigeminal nerve branches)with accessory routes from the basilar artery(pontine branch)and the external carotid(the accessory meningeal branch).Conversely,that in the dog can be said to be the external carotid(such as the middle meningeal artery,the anastomotic,the petrosal, the accessory meningeal branches and the anastomotic artery)with accessory routes from the internal carotid(direct branches.)
