After furnishing a small twig to the dura mater, the ophthalmic division travels forwards in the lateral wall of the cavernous sinus, and enters the orbit through the medium of the sphenoidal (superio...
-Superior Maxillary Division
After traversing the outer wall of the cavernous sinus, the superior maxillary division emerges from the middle cranial fossa by means of the foramen rotundum, and enters the spheno-maxillary (pterygo...
-Inferior Maxillary Division
This consists of a sensory portion derived from the Gasserian (semilunar) ganglion together with the motor root of the trigeminal. The two portions pass separately through the foramen ovale, and join ...
-Ganglia Of The Trigeminal
In addition to the Gasserian (semilunar) there are four ganglia connected with the trigeminal nerve. These are :- (a) With the Ophthalmic division-the ciliary ganglion. (b) With the Superior Max...

Deep Origin There are two separate elements in the seventh nerve, a motor portion, the facial nerve proper, and a sensory part, the pars intermedia (nervus intermedius). They unite at the bottom of...
-Eighth Or Auditory Nerve
The auditory nerve consists of two elements, cochlear and vestibular, the fibres of which arise in the internal ear from the spiral and vestibular ganglia respectively. Central Connections (a) C...
-Ninth Or Glosso-Pharyngeal Nerve
Deep Origin From the dorsal nucleus, nucleus ambiguus and tractus solitarius in the floor of the fourth ventricle, at the back of the medulla. The greater number of the fibres, however, arise from ...
-Tenth Or Vagus Nerve
Deep Origin Similar to that of the glossopharyngeal nerve, but only a few afferent fibres pass to the tractus solitarius. Superficial Origin Twelve to fifteen rootlets emerge from the medulla...
-Eleventh Or Spinal Accessory Nerve
The spinal accessory is derived partly from the brain, and partly from the spinal cord. (A) Cerebral Portion. (1) Deep Origin The nucleus ambiguus in the medulla oblongata immediately below the ...
-Twelfth Or Hypoglossal Nerve
Deep Origin From the grey matter of the floor of the fourth ventricle, and the antero-lateral part of the grey matter around the central canal. The hypoglossal nucleus extends from immediately abov...
-Spinal Nerves
There are thirty-one pairs of spinal nerves. They are named according to the vertebrae in relation to which they emerge. The thirty-one pairs comprise eight cervical, twelve thoracic, five lumbar, fiv...
-Anterior Primary Divisions Of Spinal Nerves
The anterior primary divisions are generally much larger than the posterior divisions. Each is connected, near its origin, by one or two filaments, with a ganglion of the sympathetic. With the excepti...
-Brachial Plexus
The brachial plexus occupies the lower part of the posterior triangle of the neck and the upper part of the axilla. It is formed by the anterior primary divisions of the lower four cervical nerves tog...
-From Lateral And Medial Cords. Median Nerve
(C. 6, 7, 8, T. 1). The nerve arises from the lateral and medial cords by two heads, the medial of which passes superficially to the third part of the axillary artery to reach its lateral side. It des...
-Thoracic Nerves
With the exception of the first, the anterior primary divisions of the thoracic nerves do not form plexuses, but extend forwards singly under the name of intercostal nerves. The upper six are termed t...
-Lumbar Plexus
This plexus is produced by the anterior primary divisions of the first four lumbar nerves, the first being reinforced by a communicating twig from the last thoracic. The fourth lumbar, in addition to ...
-Sacral Plexus
The sacral plexus occupies the posterior wall of the pelvic cavity, lying on the anterior surface of the piriformis muscle and behind the pelvic fascia. It is formed by the union of the lumbo-sacral c...
-Internal Popliteal
This is the larger of the two popliteal nerves, and passes down the middle of the popliteal space as far as the lower border of the popliteal muscle, where it becomes the posterior tibial nerve. At fi...
-Posterior Tibial
The posterior tibial extends from the lower border of the popliteus to a point almost midway between the medial malleolus and the calcaneum. Here, beneath the medial annular ligament (lig. laciniatum)...

-Musculo-Cutaneous
The musculo-cutaneous descends between the peroneal muscles and the extensor longus digitorum to pierce the deep fascia, as two branches, in the lower third of the leg. The two branches, the medial an...
-Sympathetic System
