| 1. | Homologous trochlear nerves are found in all jawed vertebrates.
|
| 2. | The trochlear nerve comes out of the posterior surface of the midbrain, below the inferior colliculus.
|
| 3. | The trochlear nerve then goes around the midbrain, and is visible coming out of the sides.
|
| 4. | Damage to the trochlear nerve ( IV ) can also cause diplopia with the eye adducted and elevated.
|
| 5. | This is due to impairment in the superior oblique muscle, which is innervated by the trochlear nerve.
|
| 6. | Directly rostral to the superior cerebellar peduncle, there is the superior medullary velum and then the two trochlear nerves.
|
| 7. | The nuclei of the oculomotor nerve ( III ) and trochlear nerve ( IV ) are located in the midbrain.
|
| 8. | The oculomotor nerve comes out between the peduncles, and the trochlear nerve is visible wrapping around the outside of the peduncles.
|
| 9. | The trochlear nerve emerges from the dorsal aspect of the brainstem at the level of the caudal mesencephalon, just below the inferior colliculus.
|
| 10. | CN III ), which may affect the parasympathetic input to the superior oblique ( innervated by trochlear nerve a . k . a.
