1Which cranial nerve is the only sensory nerve not to synapse in the Thalamus prior to reaching the cortex?
- AOlfactory Nerve (CNI)
- BOptic Nerve (CNII)
- CVestibulocochlear Nerve
2Pupilary constriction is a [blank_start]parasympathetic[blank_end] action mediated by the [blank_start]inferior[blank_end] division of the [blank_start]oculomotor[blank_end] nerve
- Aparasympathetic
- Bsympathetic
- Cinferior
- Dsuperior
- Eoculomotor
- Foptic
- Gfacial
3Whilst all other cranial nerves are part of the peripheral nervous system, the [blank_start]optic[blank_end] nerve is actually a central nervous system structure, due its myelin being produced by [blank_start]oligodendrocytes[blank_end] as opposed to the [blank_start]schwann cells[blank_end] that produce myelin in the PNS.
- Aoptic
- Boligodendrocytes
- Cschwann cells
4Which cranial nerve arises from the cervical spinal cord?
The [blank_start]Spinal Accessory[blank_end] Nerve- ASpinal Accessory
5The Trigeminal Nerve (CNV) has three sensory nuclei. Match the definitions to the relevant nucleus.
The Mesencephalic Nucleus [blank_start]Proprioception from chewing muscles[blank_end]
The Pontine Trigeminal Nucleus [blank_start]Touch & vibration sensation[blank_end]
The Spinal Trigeminal nucleus [blank_start]Pain & temperature sensation[blank_end]- AProprioception from chewing muscles
- BTouch & vibration sensation
- CPain & temperature sensation
6The axons of the [blank_start]lateral[blank_end] corticospinal tract cross over at the decussation of the pyramids in the medulla, whereas the [blank_start]ventral[blank_end] corticospinal tract axons cross over at their relevant spinal levels.
- Alateral
- Bventral
7Insult to which of the white matter columns of the spinal cord would result in loss of sensory aspects such as fine touch and proprioception?
- ADorsal column
- BRight lateral column
- CLeft lateral column
- DVentral column
8Which of the following Vagus nerve nuclei allows Speech to occur?
- ADorsal Nucleus
- BSolitary Nucleus
- CNucleus Ambiguus
9The [blank_start]Solitary[blank_end] Nucleus is responsible for the taste sensation via CNs VII, IX & X
- ASolitary
10The Pyramidal motor tracts comprise two systems, the cortiospinal tract and the [blank_start]corticobulbar[blank_end] tract, the latter of which providing motor function to the cranial nerves.
- Acorticobulbar
11Which part of the Diencephalon has endocrine function?
- AHypothalamus
- BThalamus
- CPituitary Gland
12The [blank_start]Reticular Formation[blank_end] is a network of nervous tissue at the centre of the brainstem that regulates the Ascending Reticular Activating System, a system that if damaged would lead to irreversible coma.
- AReticular Formation
13The Superior Colliculus houses the [blank_start]Oculomotor[blank_end] nucleus and is thus mostly associated with the visual pathway
- AOculomotor
- BOptic
- CTrochlear
- DAbducens
14Despite the superior colliculus being responsible for the visual pathway, which of the following cranial nerve nuclei associated with sight is situated within the inferior colliculus?
The [blank_start]Trochlear[blank_end] Nucleus- ATrochlear
- BOptic
- COculomotor
- DAbducens
15Both the superior and inferior colliculi exist within the [blank_start]Midbrain[blank_end]
- AMidbrain
- BPons
- CMedulla
- DThalamus
16Which muscle of the soft palate is innervated by CNV3?
The [blank_start]Tensor Veli Palatini[blank_end] muscle- ATensor Veli Palatini
17The Trigeminal Nuclei:
[blank_start]Pontine Trigeminal Nucleus[blank_end]: Main Trigeminal nucleus, responsible for touch, vibration, etc
[blank_start]Mesencephalic Trigeminal Nucleus[blank_end]: Responsible for proprioception associated with muscles of mastication- AMesencephalic Trigeminal Nucleus
- BMetencephalic Trigeminal Nucleus
- CTelencephalic Trigeminal Nucleus
- DPontine Trigeminal Nucleus
- EMedullary Trigeminal Nucleus
18Name the ganglion at which CNIX becomes the auriculotemporal branch of CNV3 in order to innervated the Parotid Gland.
The [blank_start]Otic[blank_end] Ganglion- AOtic
19The Nucleus [blank_start]Ambiguus[blank_end] gives rise to the motor fibres to the pharynx, larynx and upper oesophagus via cranial nerves IX and X.
- AAmbiguus
20The GlossopharYngeal nerve (CNIX) provides motor innervation to one muscle, name it.
The [blank_start]Stylopharyngeus[blank_end] muscle- AStylopharyngeus
21The [blank_start]Solitary[blank_end] Nucleus is responsible for taste sensation via Cranial Nerves VII, IX and X
- ASolitary
22The [blank_start]Corticobulbar[blank_end] tract is the part of the pyramidal system which gives rise to the motor aspects of the non-oculomotor cranial nerves.
- ACorticobulbar
23The [blank_start]Fornix[blank_end] is a part of the limbic system which acts as the major efferent output system of the Hippocampus.
- AFornix
