The following tests are done to assess cranial nerves and nerves involved in the response or reflex; afferent (A) and efferent (E) nerves are listed. menace response (Figure 1): A: CN II (retina); E: CN VI, CN VII; in addition, the thalamus, cerebrum, and cerebellum are involved in the response and its pathway.
1. Confirm the existence of a neurologic condition. 2. Localize the lesion (ie, make a neuroanatomical diagnosis). Repeat neurologic examinations are helpful to detect subtle changes or progression of signs. This article will discuss how to perform the neurologic examination.
Cranial Nerve Evaluation. Cranial nerves are peripheral nerves that originate primarily from the brainstem and provide sensory and motor functions to the head and neck (BOX 4). Each cranial nerve has specific functions, and most can be evaluated through the following standard tests:
Examining the Cranial Nerves in the Neurologic Examination of Animals Cranial Nerve I (Olfactory Nerve) Olfaction is tested only if the chief concern is loss of smell, most commonly in working dogs such as police or military detector dogs or hunting dogs.
The neurological examination allows: to determine if the nervous system is affected by a disease process. to localize the lesion within the nervous system (neuroanatomic diagnosis) to assess the severity of dysfunction.
The neurological examination is the most fundamental tool that neurologists use to identify and isolate problems in the central and peripheral nervous system (CNS & PNS).
A neurologic examination evaluates 1) the head and cranial nerves, 2) the gait, or walk, 3) the neck and front legs, and 4) the torso, hind legs, anus, and tail. Your pet’s reflexes will also be tested to determine, if possible, the location of the injury in the brain, spinal cord, or nerves in the peripheral nervous system.
