Which cranial nerve is the only sensory nerve not to synapse in the Thalamus prior to reaching the cortex?
Olfactory Nerve (CNI)
Optic Nerve (CNII)
Vestibulocochlear Nerve
Pupilary constriction is a parasympathetic sympathetic( parasympathetic, sympathetic ) action mediated by the inferior superior( inferior, superior ) division of the oculomotor optic facial( oculomotor, optic, facial ) nerve
Whilst all other cranial nerves are part of the peripheral nervous system, the nerve is actually a central nervous system structure, due its myelin being produced by as opposed to the that produce myelin in the PNS.
Which cranial nerve arises from the cervical spinal cord? The Nerve
The Trigeminal Nerve (CNV) has three sensory nuclei. Match the definitions to the relevant nucleus. The Mesencephalic Nucleus ❌ The Pontine Trigeminal Nucleus ❌ The Spinal Trigeminal nucleus ❌
The axons of the corticospinal tract cross over at the decussation of the pyramids in the medulla, whereas the corticospinal tract axons cross over at their relevant spinal levels.
Insult to which of the white matter columns of the spinal cord would result in loss of sensory aspects such as fine touch and proprioception?
Dorsal column
Right lateral column
Left lateral column
Ventral column
Which of the following Vagus nerve nuclei allows Speech to occur?
Dorsal Nucleus
Solitary Nucleus
Nucleus Ambiguus
The Nucleus is responsible for the taste sensation via CNs VII, IX & X
The Pyramidal motor tracts comprise two systems, the cortiospinal tract and the tract, the latter of which providing motor function to the cranial nerves.
Which part of the Diencephalon has endocrine function?
Hypothalamus
Thalamus
Pituitary Gland
The 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.
The Superior Colliculus houses the Oculomotor Optic Trochlear Abducens( Oculomotor, Optic, Trochlear, Abducens ) nucleus and is thus mostly associated with the visual pathway
Despite 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 Trochlear Optic Oculomotor Abducens( Trochlear, Optic, Oculomotor, Abducens ) Nucleus
Both the superior and inferior colliculi exist within the Midbrain Pons Medulla Thalamus( Midbrain, Pons, Medulla, Thalamus )
Which muscle of the soft palate is innervated by CNV3? The muscle
The Trigeminal Nuclei: ❌: Main Trigeminal nucleus, responsible for touch, vibration, etc ❌: Responsible for proprioception associated with muscles of mastication
Name the ganglion at which CNIX becomes the auriculotemporal branch of CNV3 in order to innervated the Parotid Gland. The Ganglion
The Nucleus gives rise to the motor fibres to the pharynx, larynx and upper oesophagus via cranial nerves IX and X.
The GlossopharYngeal nerve (CNIX) provides motor innervation to one muscle, name it. The muscle
The Nucleus is responsible for taste sensation via Cranial Nerves VII, IX and X
The tract is the part of the pyramidal system which gives rise to the motor aspects of the non-oculomotor cranial nerves.
The is a part of the limbic system which acts as the major efferent output system of the Hippocampus.
