- The trochlear nerve innervates only one muscle, the superior oblique muscle of the eye. (T/F?)
- The superior oblique muscle abducts, depresses and externaly rotates the eye. (T/F?)
- An injury to the trochlear nerve causes horizontal diplopia. (T/F?)
- An injury to the trochlear nucleus will result in symptoms in the eye on the same side. (T/F?)
- An injury to the trochlear nerve, after it exits the mesencephalon, will result in symptoms in the eye on the same side. (T/F?)
- An eye affected with the trochlear nerve palsy is positioned upwards relative to the unaffected eye. (T/F?)
89. The tarts
The cranial nerves passing through the superior orbital fissure in order from top to bottom:
- Lacrimal nerve. (T/F?)
- Frontal nerve. /T/F?)
- Trochlear nerve. (T/F?)
- Superior branch of the oculomotor nerve. (T/F?)
- Nasocilliary nerve. (T/F?)
- Abducens nerve. (T/F?)
- Inferior branch of the oculomotor nerve. (T/F?)
88. Entry and exit points of cranial nerves, arteries and veins (II)
- Anterior ethmoidal artery: Foramen cecum. (T/F?)
- Ophtalmic artery: Superior orbital fissure. (T/F?)

74. Entry and exit points of cranial nerves, arteries and veins (I)
- Supraorbital artery: Supraorbital foramen. (T/F?)
- Ophtalmic nerve: optic canal. (T/F?)
- Mandibular nerve: foramen ovale. (T/F?)
- Middle meningeal artery: foramen spinosum. (T/F?)
- Accessory nerve: foramen ovale. (T/F?)

59. Axial section through the midbrain (Gray-710)
58. Structures that leave or enter the skull through the superior orbital fissure
- Oculomotor nerve. (T/F?)
- Trochlear nerve. (T/F?)
- Frontal nerve. (T/F?)
- Superior and inferior ophthalmic veins. (T/F?)
- Ophthalmic artery. (T/F?)
- Abducens nerve. (T/F?)
53. Exits of cranial nerves from the skull
- Cribriform plate: Olfactory nerve. (T/F?)
- Optic foramen: Optic nerve. (T/F?)
- Superior orbital fissure: Ophtalmic nerve. (T/F?)
- Foramen ovale: Maxillary nerve. (T/F?)

19. Cranial nerve nuclei – location
- Trochlear nucleus: Mesencephalon?
- Dorsal cochlear nucleus: Pons?
- Ventral cochlear nucleus: Medulla?
- Oculomotor nucleus: Mesencephalon?
- Facial nucleus: Pons?
- Edinger-Westphal nucleus: Pons?
5. Trigeminal nerve
- Is the largest cranial nerve. (T/F?)
- Is both motor and sensory nerve. (T/F?)
- Has three major branches: the ophthalmic nerve, the maxillary nerve, and the mandibular nerve. (T/F?)
- One of its branches, mandibular nerve comes close to the internal carotid artery in the cavernous sinus. (T/F?)
- Its motor nucleus supplies the muscles of mastication. (T/F)
- Maxillary and mandibular nerve have sensory and motor functions. (T/F?)
