  2. Abducens nerve - Wikipedia

    en.wikipedia.org/wiki/Abducens_nerve

    The abducens nerve or abducent nerve, also known as the sixth cranial nerve, cranial nerve VI, or simply CN VI, is a cranial nerve in humans and various other animals that controls the movement of the lateral rectus muscle, one of the extraocular muscles responsible for outward gaze. It is a somatic efferent nerve.

  3. Paramedian pontine reticular formation - Wikipedia

    With the abducens nucleus it makes up the horizontal gaze centre. [1] It is situated in the pons adjacent to the abducens nucleus . [ 2 ] It projects to the ipsilateral abducens (cranial nerve VI) nucleus, and contralateral oculomotor (cranial nerve III) nucleus [ note 1 ] to mediate conjugate horizontal gaze and saccades .

  4. Pyramidal tracts - Wikipedia

    en.wikipedia.org/wiki/Pyramidal_tracts

    The upper motor neurons of the corticobulbar tract synapse with interneurons or directly with the lower motor neurons located in the motor cranial nerve nuclei, namely oculomotor, trochlear, motor nucleus of the trigeminal nerve, abducens, facial nerve and accessory and in the nucleus ambiguus to the hypoglossal, vagus and accessory nerves. [6]

  5. Medial longitudinal fasciculus - Wikipedia

    en.wikipedia.org/wiki/Medial_longitudinal_fasciculus

    The medial longitudinal fasciculus is the main central connection for the oculomotor nerve, trochlear nerve, and abducens nerve. It carries information about the direction that the eyes should move. Lesions of the medial longitudinal fasciculus can cause nystagmus and diplopia, which may be associated with multiple sclerosis, a neoplasm, or a ...

  6. Abducens nucleus - Wikipedia

    en.wikipedia.org/wiki/Abducens_nucleus

    The abducens nucleus is the originating nucleus from which the abducens nerve (VI) emerges—a cranial nerve nucleus. This nucleus is located beneath the fourth ventricle in the caudal portion of the pons near the midline, [ 1 ] medial to the sulcus limitans .

  7. Clivus (anatomy) - Wikipedia

    en.wikipedia.org/wiki/Clivus_(anatomy)

    "Clivus" is also used as an abbreviated term for the clivus ocularis, which is the sloping inner wall of the retina as it dips into the foveola in the macula of the eye. To disambiguate, the clivus is sometimes referred to as the Blumenbach clivus. This is named after Johann Friedrich Blumenbach. [citation needed]

  8. Dorello's canal - Wikipedia

    en.wikipedia.org/wiki/Dorello's_canal

    Dura mater forms a sleeve within Dorello's canal, forming an outer wall. [3] There may also be arachnoid mater. [3] This contains the abducens nerve (VI) and the inferior petrosal sinus. [2] [3] The petrosphenoidal ligament (Gruber's ligament, or petroclinoidal ligament) forms the roof of Dorello's canal. [2]

  9. Extraocular muscles - Wikipedia

    en.wikipedia.org/wiki/Extraocular_muscles

    Damage to the abducens nerve (VI) can also result in double vision. [15] This is due to impairment in the lateral rectus muscle, supplied by the abducens nerve. [14] Amblyopia also known as lazy eye is a condition of diminshed sight in one eye. Ophthalmoparesis is weakness or paralysis of one or more extraocular muscles.
