  Abducent Nerve   (Site not responding. Last check: 2007-10-20)
The nerve passes upward and anterolaterally in the subarachnoid space piercing the arachnoid and dura lateral to the dorsum sellae of the sphenoid bone.
nerve is most vulnerable in its pathway from the pons to the cavernous sinus especially at the apex of the petrous temporal bone, which is commonly involved in fractures of the base of the skull.
Lesions of the sixth nerve at the cavernous sinus.

 IX. Neurology. 1F. The Abducent Nerve. Gray, Henry. 1918. Anatomy of the Human Body.
The abducent nerve is joined by several filaments from the carotid and cavernous plexuses, and by one from the ophthalmic nerve.
As these nerves pass forward to the superior orbital fissure, the oculomotor and ophthalmic divide into branches, and the abducent nerve approaches the others; so that their relative positions are considerably changed.
Below the optic nerve are the inferior division of the oculomotor, and the abducent, the latter lying on the medial surface of the Rectus lateralis.

Abducent nerve: A small motor nerve that has one task: to supply a muscle called the lateral rectus muscle that moves the eye outward.
All 12 cranial nerves, the abducent nerve included, emerge from or enter the skull (the cranium), as opposed to the spinal nerves which emerge from the vertebral column.
The abducent (or abducens) operates the lateral rectus muscle that draws the eye toward the side of the head.

 IX. Neurology. 5g. The Facial Nerve. Gray, Henry. 1918. Anatomy of the Human Body.
At the anterior end of the nucleus of the abducent nerve they make a second bend, and run downward and forward through the pons to their point of emergence between the olive and the inferior peduncle.
The central branches leave the trunk of the facial nerve in the internal acoustic meatus, and form the sensory root; the peripheral branches are continued into the chorda tympani and greater superficial petrosal nerves.
Entering the brain at the lower border of the pons between the motor root and the acoustic nerve, the fibers of the sensory root pass into the substance of the medulla oblongata and end in the upper part of the terminal nucleus of the glossopharyngeal nerve and in the fasciculus solitarius.

This triangle is situated between the ophthalmic and maxillary divisions of the trigeminal nerve and the bone of the middle fossa between the foramen rotundum and superior orbital fissure (Figs.
This triangle is bounded by the greater superficial petrosal nerve medially, the posterior aspect of the mandibular division of the trigeminal nerve anteriorly, and by a line between the foramen spinosum and the arcuate eminence of the petrous bone posteriorly.
The landmarks for this area in the middle fossa are the posterior border of the mandibular division of the trigeminal nerve anteriorly, the arcuate eminence posteriorly, the greater superficial petrosal nerve laterally, and the petrous ridge with the superior petrosal sinus medially.

The oculomotor, trochlear, ophthalmic, and abducent nerves bear certain relations to each other in the cavernous sinus, at the superior orbital fissure, and in the cavity of the orbit, as follows: In the cavernous sinus (Fig.
(Picture From the Classic Gray's Anatomy) In the orbit the trochlear, frontal, and lacrimal nerves lie immediately beneath the periosteum, the trochlear nerve resting on the Obliquus superior, the frontal on the Levator palpebræ superioris, and the lacrimal on the Rectus lateralis.
The superior division of the oculomotor nerve lies immediately beneath the Rectus superior, while the nasociliary nerve crosses the optic nerve to reach the medial wall of the orbit.

The anatomy of the abducent nerve is well known; its duplication (ranging from 5 to 28.6%), however, has rarely been reported in the literature.
In two (25%) of these eight specimens the nerve originated at the pontomedullary sulcus as two independent trunks: in one case the superior trunk was thicker than the inferior and in the other it was thinner.
Although the presence of a duplicated abducent nerve is a rare finding, preoperative magnetic resonance imaging should be performed to rule out this possibility, thus tailoring the operation to avoid postoperative deficits.

The abducens nerve emerges from the ipsilateral abducens nucleus between the caudal pons beneath the floor of the fourth ventricle and the medulla (the pontomedullary junction).
The lateral rectus muscle of the eye that the abducens nerve innervates is opposed by the action of the medial rectus muscle.
Damage to the abducens nerve causes medial strabismus as the individual is no longer able to control lateral eye movement via the lateral rectus motor neurons.
