Causes abduction of the eyeball. So named: abducens nerve
The abducens is another nerve sending controlling impulses to an eyeball muscle.
The abducens nerve (cranial nerve VI) is tested by examining lateral eye movement. Ask the patient to look laterally towards each side to assess for any weakness or limited movement of the eye. Additionally, performing the "H test" can help evaluate if there is any dysfunction of the abducens nerve.
The nerves involved in diplopia include three cranial nerves: the oculomotor nerve (third cranial nerve), the abducens nerve (sixth cranial nerve), and the trochlear nerve (fourth cranial nerve).
You are speaking of the 12 cranial nerves:I. Olfactory nerve which branches out of the telencephalonII. Optic which branches out of the diencephalonIII. Oculomotor nerve which branches out of the mesencephalonIV. Trochlear nerve nerve which branches out of the mesencephalonV. Trigeminal nerve which branches out of the ponsVI. Abducens nerve which branches out of the ponsVII. Facial nerve which branches out of the ponsVIII. Vestibulochochlear nerve which branches out of the ponsIX. Glossopharangeal nerve nerve which branches out of the medullaX. Vagus nerve nerve which branches out of the medullaXI. Accessory nerve nerve which branches out of the medulla & cervical spineXII. Hypoglossal nerve nerve which branches out of the medulla
It's due to pontine lesion that destroys abducens nerve, facial nerve and corticospinal tract of one side.paralysis of lateral rectus muscle on the same side = due to damaged abducens nerveparalysis of facial expression muscles, and loss of other functions on the same side = due to damaged facial nerveparalysis of contralateral limbs = due to damaged corticospinal tract

Abducens
There are three cranial nerves that innervates muscle to move the eye. The main cranial nerve that controls eye movement is occulomotor nerve (CN III). It is responsible for inferior rectus, superior rectus, medial rectus, and inferior oblique. Lateral rectus muscle is innervated by abducens nerve (CN VI). Superior oblique muscle is innervated by trochlear nerve (CN III).
The lateral rectus muscle, innervated by the 6th cranial nerve (the Abducens)

The nerves involved in diplopia include three cranial nerves: the oculomotor nerve (third cranial nerve), the abducens nerve (sixth cranial nerve), and the trochlear nerve (fourth cranial nerve).
Abducent nerve. Also called as abducens nerve. The sixth cranial nerve. Superior oblique muscle is supplied by trochlear nerve. All other muscles are supplied by oculomotor nerve.

Hypoglossal nerve nerve which branches out of the medulla
The main nerve required would be the optic nerve (II), although you would also use the ocular motor nerve (III) to move the eyes. Other cranial nerves involved are: Trochlear nerve (IV) and Abducens nerve (VI).
