CN V (trigeminal)

Which cranial nerve provides motor innervation to the tongue?

CN XII

Which cranial nerve provides motor innervation to the muscles of facial expression?

CN VII (facial)

Which cranial nerve provides motor innervation to the dorsal oblique muscle?

CN IV (trochlear)

Assuming all other neurological findings are unremarkable, a lesion at which ONE of the neuroanatomical locations listed below would best explain the following findings: Tetraparesis with absent tendon reflexes (0) and decreased withdrawal reflexes (1+) in all four limbs?

Peripheral nerves

Which of the following occurs with central vestibular disease, but does not occur with peripheral vestibular disease?

Vertical nystagmus

Assuming all other neurological findings are unremarkable, a lesion at which ONE of the neuroanatomical locations listed below would best explain the following findings: Tetraparesis with hyperreflexia in all four limbs?

C1 - C5

Assuming all other neurological findings are unremarkable, a lesion at which ONE of the neuroanatomical locations listed below would best explain the following findings: Severe right temporal muscle atrophy developing over 10 days. Right eye – normal menace response, decreased palpebral reflex.  There is decreased facial sensation over the region of the right nostril and muzzle.

CN V (right)

Which nerve, combination of nerves or neuroanatomical region(s) below is evaluated by: The pupillary light response (PLR)?

CN II + III

Which nerve, combination of nerves or neuroanatomical region(s) below is evaluated by: The menace response?

CN II + VII

Which nerve, combination of nerves or neuroanatomical region(s) below is evaluated by: Conscious proprioception from the forelimb?

Cerebrum, brainstem, C1-T2

Which nerve, combination of nerves or neuroanatomical region(s) below is evaluated by: The occulovestibular reflex?

CN III, IV, VI (abducens) + VIII (vestibulocochlear)

Circling caused by unilateral vestibular lesions is usually ipselateral (i.e. towards the side of the lesion).  Is this True or False?

True

Deep pain sensation should always be tested in animals with exaggerated spinal (UMN) reflexes.  Is this True or False?

False

Assuming all other neurological findings are unremarkable, a lesion at which ONE of the neuroanatomical locations listed below would best explain the following findings: Recent onset of seizures, pacing in circles to the right, reduced menace response in the left eye and decreased conscious proprioception in the left fore and hind limbs?

Right cerebral cortex and occipital lobe

Assuming all other neurological findings are unremarkable, a lesion at which ONE of the neuroanatomical locations listed below would best explain the following findings: Right hemiparesis, with decreased spinal reflexes in the radial, musculocutaneous and axillary nerves, and exaggerated reflexes in right femoral and sciatic nerves

Right C6-T2
