V{3}), through which the third branch of the trigeminalnerve leaves the cranium.
V{2}), through which the second branch of the trigeminal nerve passes out.
Further forward in front of the stapes is the small opening for the exit of the facial nerve, and seen in a lateral view close to the orbitosphenoid, that for the trigeminal (fig.
Just in front of this is a large round hole, the =trigeminal foramen= (fig.
V), through which the whole of the trigeminal nerve passes out.
Anteriorly it is pierced by a pair of small foramina through which the ophthalmic branches of the trigeminal nerve pass out.
Between the trigeminaland optic foramina are the very small foramina for the sixth nerves (fig.
Lying below and slightly external to this is a large foramen, through which part of the second branch of the trigeminal enters on its way to the infra-orbital foramen and so to the side of the face.
These perforate the palatine and transmit branches of the trigeminal nerve and certain blood-vessels.
Anteriorly each cord ends in the Gasserian ganglion of the trigeminal nerve and posteriorly it is united with the coccygeal nerve by a varying number of branches.
This comparison implies that the motor part of the trigeminal nerve originally supplied the prosomatic appendages.
In the adult Petromyzon the trigeminal nerve innervates specially a massive suctorial apparatus, by means of which it holds on to other fishes, or to stones in the bottom of the stream.
Killian comes to much the same conclusion as Dohrn, for he finds seventeen to eighteen separate mesoderm segments in the head, of which twelve belong to the trigeminal and facial region.
The metastoma, which has become in Ammocoetes the lower lip supplied by the velar or mandibular branch of the trigeminal nerve (7); 2.
The next question to consider is the evidence obtained by morphologists and anatomists as to the number of segments supplied by the trigeminal nerve-group; this question will be considered in the next chapter.
The analysis of these tentacular segments belonging to the trigeminal nerve presents greater difficulties than that of any of the other cranial segments, owing to the deficiency of our knowledge of what occurs at transformation.
It is usually subcutaneous, and is frequently situated on the head or neck in the distribution of the trigeminal or superficial cervical nerves.
One can hope for success only if the tic is of reflex origin, where extraction of a tooth, or local treatment of an ulcer, or resection of part of the trigeminal nerve may be indicated.
No tic could have been attended with such a result, whereas compression of branches of the trigeminal at their points of exit might determine reflex tonic contraction of the orbicularis, and so, for that matter, might a central lesion.
The case of intracranial neoplasm mentioned by Oppenheim, in which irritation of the upper branch of the trigeminalwas accompanied by homolateral facial contraction, is wholly comparable to the so-called "tic douloureux.
Resection of a branch of the trigeminal is valueless; facial elongation only causes a corresponding paralysis, and should this latter accident be transient, as in a case of Bernhardt's, so is the relief from the tic.
It might then be a good plan to divide the branches of the superficial cervical plexus, just as the trigeminalis divided for tic douloureux of the face.
Taking all the circumstances into consideration, we think the hypothesis tenable that the trigeminal is implicated in the pathogeny of the spasm, although the condition is not strictly comparable to the classic tic douloureux.
The father is neurasthenic, and the grandfather has trigeminal neuralgia.
There is severe pain referred to the distribution of the maxillary division of the trigeminal nerve.
The facial and acoustic nerves and the maxillary and mandibular divisions of the trigeminal are frequently implicated.
The most important surgical affection of this nerve is "trigeminal neuralgia," which has already been described (Volume I.
Pain is a variable symptom; when present, it usually radiates along the branches of the first and second divisions of the trigeminal nerve.
The patient complains of a constant gnawing pain in the tongue, and of severe pain shooting along the branches of the trigeminal nerve, and especially towards the ear.
This condition may be induced reflexly from irrigation of the trigeminal nerve, notably of branches that supply the nasal cavities and the teeth.
This is associated with severe pain, which is not confined to the diseased tooth, but may spread to adjacent teeth, and sometimes to all the branches of the trigeminal nerve on the same side of the face.
The plexiform neuroma forms a loose soft tumour situated in the course of one or more branches of the trigeminal nerve, especially the supra-orbital branch.
The origin is fleshy from the posterior wall of the orbit, dorsal to the foramen of the trigeminal nerve, lateral to the origin of M.
The origin is fleshy from the posterior wall of the orbit medial to the foramen of the trigeminal nerve and also medial to the origin of M.
The trigeminal nerve leaves a slight impression on the ventral surface of the muscle near its origin (figs.
The anterior margin of the origin is at the point where the mandibular ramus of the trigeminal nerve enters the mandible.
But such a measure as the compression of the carotid in trigeminal neuralgia is of very doubtful propriety; I suspect the consequent anaemiation of the brain more than does away with any benefit that might be mechanically produced.
The most common variety of trigeminal neuralgia is migraine, or sick-headache, as it is often called.
The lesions of taste and smell disappeared exactly pari passua with the trigeminal pains.
Common sensation was reported by Notta as affected in only three cases out of a hundred and twenty-eight; but my own experience has afforded a much larger proportion of instances in trigeminal neuralgia.
In the present state of our information I am inclined to explain all the congestive complications of trigeminal neuralgia on the basis of vaso-motor paralysis.
With all this, however, we see a sufficiently large number of incurable sciaticas, on the one hand, and of severe trigeminal neuralgia cured on the other.
For instance, sciatica, though by no means so frequently a mild and trifling complaint as Eulenburg would make it to be, is certainly, on the whole, more curable than the trigeminal neuralgias taken as a group.
To bring subjects out of Levantman shock, you let them have a squirt of simple saline in the trigeminal nerve.
The potter found the apex of the trigeminal nerve with his needle's point and gave him 60 cc.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "trigeminal" in a variety of sentences. We hope that you will now be able to make sentences using this word.
