To review the anatomy of the vestibular system and the pathophysiology of the vestibular disease. How to distinguish between peripheral and central vestibular disease. To review differential diagnoses and diagnostic testing for both peripheral and central vestibular disease.
Dogs and cats with peripheral vestibular disease typically display head tilt, spontaneous (resting) nystagmus, strabismus, and ataxia. Falling and rolling may also be observed. Other cranial nerves that can be affected because of their proximity to CN VIII in the petrous temporal bone are CN VII and the sympathetic innervation to the eye (i.e ...
The NeuroMap is based on mapping the main neural functions on a diagram of the nervous system. If a lesion is in a particular area, you can read from the NeuroMap which neural functions could be disrupted and conversely, which neural functions will be normal.
Figure 3. Vibrissae response: Touch the upper lip; the patient may move the lip only or turn the head away. Figure 4. auricular reflex: The inner pinna is innervated by CN VII; the response should be twitching of the ear, blinking, or shaking of the head.
The vestibular nerve is one of the terminal branches of the vestibulocochlear nerve (along with the cochlear nerve). It is the nerve of equilibration which also provides information on body position, and the ventral root of the vestibulocochlear nerve.
Vestibule, Labyrinth / physiology* The vestibular system is responsible for keeping an animal oriented with respect to gravity. It is a sensory system that maintains the position of the eyes, body, and limbs in reference to the position of the head. Proper interpretation of neurologic deficits and precise neuroanatomic localization a …
10 Αυγ 2020 · Vestibular disease (VD) is characterized by a dysfunction of the parts of the nervous system responsible for the maintenance of equilibrium and balance. 1 The diagnosis of VD is based on cardinal neurological examination abnormalities such as ataxia, head tilt, and pathological nystagmus and strabismus.
