Sixth nerve palsy, or abducens nerve palsy, is a disorder associated with dysfunction of cranial nerve VI (the abducens nerve), which is responsible for causing contraction of the lateral rectus muscle to abduct (i.e., turn out) the eye. [1]
There are several options of treatment when iatrogenic (i.e., caused by the surgeon) spinal accessory nerve damage is noted during surgery. For example, during a functional neck dissection that injures the spinal accessory nerve, injury prompts the surgeon to cautiously preserve branches of C2, C3, and C4 spinal nerves that provide supplemental innervation to the trapezius muscle.

Abducens nerve Strabismus (ipsilateral lateral rectus muscle paralysis - the affected eye looks down and towards the nose). Depending upon the size of the infarct, it can also involve the facial nerve .
The oculomotor nerve controls all the muscles that move the eye except for the lateral rectus and superior oblique muscles. It also serves to constrict the pupil and open the eyelid. The onset of a diabetic third nerve palsy is usually abrupt, beginning with frontal or pain around the eye and then double vision. All the oculomotor muscles ...
Middle alternating hemiplegia (also known as Foville Syndrome) typically constitutes weakness of the extremities accompanied by paralysis of the extraocular muscle, specifically lateral rectus, on the opposite side of the affected extremities, which indicates a lesion in the caudal and medial pons involving the abducens nerve root (controls movement of the eye) and corticospinal fibers ...
Existing treatments aim to suppress the immune system to prevent further damage to nerve cells. A new study has developed a treatment that can help regenerate myelin with the potential to stop and ...
Damage to the abducens nucleus does not produce an isolated sixth nerve palsy, but rather a horizontal gaze palsy that affects both eyes simultaneously. The abducens nucleus contains two types of cells: motor neurons that control the lateral rectus muscle on the same side, and interneurons that cross the midline and connect to the contralateral ...
IBS symptoms in women can also be triggered or worsened by menstruation, though the reason why isn't completely clear. Stress can also spark symptoms of IBS. "Some people say the GI tract is a ...
