The abducens (also called abducent) nerve (CN VI) is the last of the three visual motor nerves. It is a brainstem structure that is located in the dorsal aspect of the pons, deep to the facial colliculus in the 4th ventricle (rhomboid fossa). As the fibers of CN VI emerge from the pons, they travel ventrally, to leave the brain parenchyma The abducens nerve crosses posterior to the paraclival (vertical petrous) internal carotid artery (ICA) approximately halfway between foramen lacerum and the sellar floor, and is the critical nonvascular landmark. The lower clivus then extends from the floor of the sphenoid to the foramen magnum and includes the jugular foramen/medial jugular.

Esotropia (eye moves inward) of the affected eye due to the unopposed action of the medial rectus muscle. Abducens nerve palsy is a common clinical finding in neurology practice. In many instances, the origin is obvious and management straightforward; however, the list of possible etiologies and mimics is vast and diverse and diagnostic decisions can be challenging and even controversial. This is especially true when the abducens nerve is affected in isolation, since in the current era of cost.

Abducens (abducent) nerve is a cranial nerve which originated from the ventral surface of the medulla oblongata. It innervates the lateral rectal muscle of eye ball. It is a motor nerve and controls the movement of the eye ball. Hence, if abducens nerve is injured in man, movement of eyeball will be affected Abducens Nerve. The abducens nerve originates from neuronal cell bodies located in the ventral pons. These cells give rise to axons that course ventrally and exit the brain at the junction of the pons and the pyramid of the medulla. The nerve of each side then travels anteriorly where it pierces the dura lateral to the dorsum sellae. The nerve.
