If results are equivocal due to poor technique or an uncooperative patient, other tests can be performed to confirm findings. This is used to evaluate the optic nerve, forebrain, cerebellum, and facial nerve. Veterinary professionals lack the luxury of patients describing their medical problem and, therefore, must rely on studious examination to reach a conclusion.1 In patients presenting with neurologic signs, systematic examination of the nervous system can identify an area of concern, a process called neuroanatomic localization.2 The neurologic examination, joined with patient history and physical examination, is therefore an invaluable diagnostic and monitoring tool in veterinary medicine. The patient is lifted straight up; then lowered to the ground. Motor to larynx and pharynxSensory supply to pharynxParasympathetic supply to viscera Strabismus, or deviation of 1 or both eyes, can occur naturally in certain breeds (e.g., pug).

Respiratory rate and effort, cardiac output, blood pressure, endocrine regulation, and basal organ functions depend upon the integrity of the brain and spinal cord. can be neurologic or orthopedic in origin. Figure 12.1 Prioritization and approach to severe neurological signs in the ICU patient. However, in clinical practice, knowledge of the nervous system and familiarity in performing the neurologic examination allows for creation of a more comprehensive care plan and rapid detection of concerning findings, as well as proving advantageous in emergency situations. At the next treatment time, the patient is observed to be nonresponsive with bilateral mydriasis and absent pupillary light reflex.
