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.

Function of abducens nerve?
The abducens nerve (cranial nerve VI) controls the lateral rectus muscle of the eye, which is responsible for abducting (moving the eye away from the nose) the eye. Dysfunction of the abducens nerve can result in horizontal double vision (diplopia) and difficulty moving the affected eye laterally.
The abducens nerve supplies the?
The abducens nerve supplies the lateral rectus muscle of the eye, which is responsible for abduction (outward movement) of the eye. This nerve is important for proper eye movement and coordination.
What nerves are involved in diplopia?
The cranial nerves involved in diplopia are the third (oculomotor), fourth (trochlear), and sixth (abducens) cranial nerves, which control eye movement and coordination. Issues with these nerves can result in misalignment of the eyes, leading to double vision.
What is the 12 pairs of peripheral nerves that branch out from the brain?
The 12 pairs of peripheral nerves that branch out from the brain are the olfactory nerve, optic nerve, oculomotor nerve, trochlear nerve, trigeminal nerve, abducens nerve, facial nerve, vestibulocochlear nerve, glossopharyngeal nerve, vagus nerve, accessory nerve, and hypoglossal nerve.
What are the causes and clinical manifestations of Millard-Gubler syndrome?
Millard-Gubler syndrome is caused by a lesion or stroke affecting the ventral pons where the corticospinal tract and abducens nerve fibers are located. Clinical manifestations include contralateral hemiplegia with ipsilateral facial nerve paralysis (palsy of the sixth and seventh cranial nerves), along with other signs of a pontine lesion such as crossed sensory deficits and horizontal gaze palsy.
Function of abducens nerve?
The abducens nerve (cranial nerve VI) controls the lateral rectus muscle of the eye, which is responsible for abducting (moving the eye away from the nose) the eye. Dysfunction of the abducens nerve can result in horizontal double vision (diplopia) and difficulty moving the affected eye laterally.
The abducens nerve supplies the?
The abducens nerve supplies the lateral rectus muscle of the eye, which is responsible for abduction (outward movement) of the eye. This nerve is important for proper eye movement and coordination.
What nerve causes lateral movement of the eye?
abducens nerve
What nerve stimulates the lateral rectus muscle of the eye?
Abducens
What cranial nerve is responsible for moving the eye laterally?
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).
What abducts the eye?
The lateral rectus muscle, innervated by the 6th cranial nerve (the Abducens)
What cranial nerve is chiefly responsible for eye movements?
oculomotor, trochlear, abducens
What nerves are involved in diplopia?
The cranial nerves involved in diplopia are the third (oculomotor), fourth (trochlear), and sixth (abducens) cranial nerves, which control eye movement and coordination. Issues with these nerves can result in misalignment of the eyes, leading to double vision.
Which cranial nerve is responsible for lateral movement of the eye?
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.
What is the 12 pairs of peripheral nerves that branch out from the brain?
The 12 pairs of peripheral nerves that branch out from the brain are the olfactory nerve, optic nerve, oculomotor nerve, trochlear nerve, trigeminal nerve, abducens nerve, facial nerve, vestibulocochlear nerve, glossopharyngeal nerve, vagus nerve, accessory nerve, and hypoglossal nerve.
Which cranial nerve is used in reading the paper?
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).
Which of the external eye muscles is controlled by cranial nerve VI?
The lateral rectus muscle is controlled by cranial nerve VI, also known as the abducens nerve. This muscle is responsible for moving the eye outward, away from the nose.
