23. You are performing a neurological exam on a puppy with pelvic limb weakness. The patellar reflex in both hind limbs is normal. Which of the following is true? a) The lesion is affecting motor neurons in the lumbar intumescence. b) The lesion is affecting efferent fibers innervating the quadriceps muscles. () The lesion does not involve the lumbar intumescence. d) The lesion is affecting afferent fibers innervating the quadriceps muscles. 24. Tick paralysis decreases release of the neurotransmitter acetylcholine (ACh] at the neuromuscular junction. Which of the following toxins would have the same effect on the postsynaptic muscle? al A toxin that blocks the breakdown of ACh in the synaptic cleft (6) )A toxin that prevents ACh from binding to ACh receptors c) A toxin that acts as an ACh agonist at the postsynaptic receptors. d) A toxin that depolarizes muscle fibers. - 1 25. You are examining a horse with proprioceptive deficits on the left side of the body. There are no apparent deficits on the right side. When you test for sensory deficits at the level of the head, you detect deficits from all branches of the left trigeminal nerve. Where would you predict the lesion to be? ap brain b) spinal cord "cl Horsal root ganglion Sensory dj neuromuscular junction el muscle spindle 26. You wish to withdraw cerebral spinal fluid (CSF) from a puppy for analysis. In order to obtain a sample, where should the tip of your needle be? - courbellomedullary cistem a) lateral ventricle byepidural space in the vertebral canal c) epidural space in the cranial cavity subarachnoid space el mesencephalic aqueduct Sensory - 1 27. A lesion in the thalamus would be expected to affect the: al patellar reflex b) panniculus reflex cl thoracic limb withdrawal reflex d)"palpebral reflex @Dnone of the above reflexes
