1. Which of the following is TRUE regarding brain disease?
Weakness is a common feature of brainstem disease but not of forebrain disease
Stupor can be seen with focal brainstem disease or with severe, widespread forebrain disease
Cranial nerve deficits may indicate brainstem disease
A normal gait with postural deficits may indicate a forebrain lesion
All of the above

2.Which group of clinical signs best describes cerebellar disease?
Hypermetria, menace deficits, intention tremor, titubation / truncal sway
Vestibular signs, weakness of the limbs, facial paralysis
Seizures, nystagmus, inappropriate urination, disorientation
Loss of learned behavior, menace deficit without PLR changes, circling to the right
All of the above may be caused by cerebellar disease

3. You are presented with a patient that has suffered an acute and severe thoracolumbar spinal cord injury and is demonstrating Schiff-Sherrington posture (laterally recumbent, head arched back, increased extensor tone in the thoracic limbs). When supporting the patient, what would you expect for the postural reactions in the thoracic limbs (TL) and pelvic limbs (PL)?
TL – Absent, PL – Absent
TL – Normal, PL – Normal
TL – Normal, PL – Absent
TL – Absent, PL – Normal
None of the above

4. What result would you expect for postural reactions in a dog with Myasthenia Gravis?
Normal in all limbs
Absent in all limbs
Absent in pelvic limbs
Absent in thoracic limbs
Exaggerated in all limbs

5. What would be the most common reason that a dog with an oblique, non-displaced, mid-shaft, femoral fracture would show apparent proprioceptive deficit in the affected limb?
Concurrent injury to nerves of the affected limbs
Concurrent muscle injury
Reluctance to bear weight/move the affected limb
Vascular insult to the spinal cord
Traumatic brain injury

6. Which of the following is NOT a type of ataxia based on anatomic location?
Cerebellar ataxia
Lower motor neuron ataxia
Vestibular ataxia
Spinal / proprioceptive ataxia
All of the above are types of ataxia based on anatomic location

7. Which of the following is a TRUE expectation of reflex testing?
Useful in evaluation of brain lesions.
Increased reflexes are common with all spinal cord lesions.
Normal spinal reflex examination is often present with Myasthenia Gravis.
Electrodiagnostic testing is not a useful extension of the reflex examination.
Normal reflexes indicate nerve or muscle disease.

8. What is the most reliable spinal reflex to assess sciatic nerve function?
Flexor (withdrawal) reflex
Gastrocnemius reflex
Extensor toe (Babinski’s) reflex
Biceps reflex
Extensor carpi radialis reflex

9. The cutaneous trunci (CT) reflex can helpful in assessing spinal cord function. Which statement is TRUE?
An absent CT reflex can often be associated with intracranial disease.
Patients with spinal cord disease will have an exaggerated CT reflex.
The CT reflex is often absent when the skin is pinched caudal to a spinal cord injury.
A spinal cord injury at the C5-6 disk space will abolish the CT reflex.
Movement of the CT reflex cranially after a back surgery is a good prognostic indicator for recovery.

10. What is the most reliable spinal reflex obtained in the thoracic limb?
Flexor (withdrawal) reflex
Triceps reflex
Extensor toe (Babinski’s) reflex
Biceps reflex
Extensor carpi radialis

11. The biceps reflex is occasionally used to help assess the function of the brachial plexus. Which of the following nerves is responsible for the resulting elbow flexion?
Lateral thoracic nerve
Ulnar nerve
Tibial nerve
Musculocutaneous nerve
Phrenic nerve
