Cranial Nerves &Vess
CT/MR of Cranial Nerves and Vessels
| Question | Answer |
|---|---|
| Which cranial nerve carries information about smells from the nasal cavity? | Cranial Nerve 1- olfactory |
| Which cranial nerve carries visual signal from the retina of the eye? | Cranial Nerve 2-optic |
| Which cranial nerve controls the muscles of the eye except the lateral rectus and superior oblique? | Cranial Nerve 3- Oculomotor |
| Which cranial nerve controls the superior oblique eye muscles? | Cranial Nerve 4- Trochlear |
| Which cranial nerve carries sensory inputs from the face, eyes, teeth and controls chewing muscles? | Cranial Nerve 5- Trigeminal |
| Which cranial nerve controls the muscles that moves the eye laterally? | Cranial Nerve 6- Abducens |
| Which cranial nerve controls the muscles of facial expression and sensory information from taste of the anterior two-thirds of the tongue? | Cranial Nerve 7- Facial |
| Which cranial nerve carries sensory input from the ears about hearing and equilibrium? | Cranial Nerve 8- Vestibular cochlear |
| What is an alternative name for the Vestibular Cochlear nerve? | Acoustic |
| What are the three branches of the trigeminal nerve? | ophthalmic, maxillary, and mandibular |
| Which cranial nerve carries motor and sensory information about taste from the posterior tongue and controls swallowing? | Cranial Nerve 9- Glossopharyngeal nerve |
| Which cranial nerve is known as the wandering nerve? | Cranial Nerve 10- Vagus |
| Which cranial nerve extends into the thorax and abdomen to control many vital functions like heart rate, gastric motility, respiration, BP? | Cranial Nerve 10- Vagus |
| Which cranial nerve controls movement of the neck and shoulders? | Cranial Nerve 11- accessory (spinal accessory) |
| Which cranial nerve controls movement of the tongue? | Cranial Nerve 12- hypoglossal |
| What are the 5 branches of the facial nerve? | temporal, zygomatic, buccal, marginal, cervical |
| Which cranial nerve carries parasympathetic innervation of organs? | Vagus nerve- #10 |
| What major arteries supplies blood to the brain? | RT & LT internal carotid arteries & RT & LT vertebral artery |
| What artery does the basilar artery receive blood from? | vertebral arteries |
| What areas of the brain does the internal carotid artery and its branches supply blood to? | frontal, temporal & parietal |
| What major arteries supply blood to the posterior circulation of the brain | RT & LT vertebral arteries : they give rise to the basilar artery and the basilar artery gives rise to the posterior cerebral arteries |
| What are the arterial branches of the internal carotid arteries | anterior cerebral arteries; middle cerebral arteries; anterior and posterior communicating arteries |
| What arteries supply blood to the frontal lobes? | Rt & LT anterior cerebral arteries |
| What artery is considered a direct extension of the internal carotid artery and is most common for CVA? | middle cerebral artery |
| What arteries supply blood to the temporal and parietal areas of the brain? | RT & LT middle cerebral arteries |
| What arteries supply blood to the occipital lobes? | Rt & LT posterior cerebral arteries |
| What arteries are considered part of the Circle of Willis | internal carotid arteries. middle cerebral arteries, anterior cerebral arteries, posterior cerebral arteries, anterior & posterior communicating arteries |
| What is the name of the system that drains blood from the brain? | Dural Venous Sinuses |
| Which dural venous sinus drain the upper cerebral hemisphere? | superior sagittal sinus |
| Which dural venous sinus drains blood from the deep and medial aspects of the brain? | inferior sagittal sinus, Vein of Galen, straight sinus |
| Which is the name of the area where the dural sinuses converge? | confluence of sinuses |
| What is an alternative name for the Vein of Galen? | Great cerebral Vein |
| Which transverse sinus is generally larger? | The RT transverse sinus is generally larger because it is considered to be a direct extension of the superior sagittal sinus. |
| What is the best imaging modality for imaging of the dural sinuses? | MR; MRV (MR venography) |
| Is contrast needed for a CTA examination? | Yes |
| Do MRA examinations use contrast? | Due to inherent contrast between vessels and background tissues contrast is not needed, but can increase vessel conspicuity if used. |
