More rarely, the oculomotor nerve and trochlear nerve ( weakness of the muscles of facial expression on one or both sides of the face.
12.
In patients with HGPPS, the absence of Robo3 / Rig1 prevents axons in the corticospinal tract and the trochlear nerve from growing past the midline.
13.
The unique features of the trochlear nerve, including its dorsal exit from the brainstem and its contralateral innervation, are seen in the primitive brains of sharks.
14.
Alfred Bielschowsky's head tilt test is a test for palsy of the superior oblique muscle caused by damage to cranial nerve IV ( trochlear nerve ).
15.
Superior oblique myokymia is an uncommon neurological condition caused by vascular compression of the trochlear nerve resulting in repeated, brief, involuntary episodes of movement of the eye.
16.
It has less commonly been associated with spasm of nystagmus and associated ocular motility deficits including skew deviation, oculomotor nerve palsy, trochlear nerve palsy and internuclear ophthalmoplegia.
17.
To compensate for this, patients with trochlear nerve palsies tilt their heads to the opposite side, in order to fuse the two images into a single visual field.
18.
Cranial nerve III ( the occulomotor nerve ) emerges ventrally from the midbrain, while the CN IV ( the trochlear nerve ) emerges out from the dorsal aspect of midbrain.
19.
Damages to these structures produce the ipsilateral presentation of paralysis or palsy due to the lack of cranial nerve decussation ( aside from the trochlear nerve ) before innervating their target muscles.
20.
The inferior colliculi together with the caudal to its counterpart-the superior colliculus-above the trochlear nerve, and at the base of the projection of the medial geniculate nucleus and the lateral geniculate nucleus.
