Describe the complete neurologic exam for a dog that comes in with a vestibular lesion.
|
Mental Staus: normal?
Posture: Head Tilt, Leaning, Wide based stance Gait: Vestibular ataxia (falling to one side + above) Abnormal movements: none? Muscle tone: none? Palpation: normal Postural reactions, Reflexes, Sensation: normal |
|
|
|
List all of the cranial nerves with sensory function.
|
olfactory, optic, vestibulocochlear, (1, 2, 8)
both sensory and motor: trigeminal, facial, glossopharyngeal, vagus (5, 7, 9, 10) |
|
|
|
List all of the cranial nerves with motor function.
|
oculomotor, trochlear, abducens, accessory, hypoglossal (3, 4, 6, 11, 12)
both motor and sensory: trigeminal, facial, glossopharyngeal, vagus (5, 7, 9, 10) |
|
|
|
Olfactory Nerve (I)
|
sensory to olfactory stimuli
|
|
|
|
Optic Nerve (II)
|
sensory to visual stimuli
|
|
|
|
Optic Nerve (II)
|
sensory to visual stimuli
|
Assess by PLR and Menace Response
|
|
|
Oculomotor (III)
|
motor to pupillary constrictor muscle and extraocular eye muscles
function allows dorsal, ventral, and medial movement of globe ...what disease condition may present with similar clinical signs? |
Horner's syndrome
(Dysfunction may result in: inability to move eye dorsal, medial, and ventral resting ventrolateral strabismus inability to contrict pupils slight ptosis |
|
|
Trochlear (IV)
|
motor to extraocular eye muscles
LR26 SO4 (Superior Oblique muscles) |
Dysfunction results in:
inability to move eye ventral and lateral. resting dorsolateral strabismus |
|
|
Trigeminal Nerve (V)
|
Sensory to the face and motor to the muscles of mastication
|
Assess by palpebral reflex (sensory) and palpate muscle of mastication for motor function.
|
|
|
Abducens Nerve (VI)
|
Motor to the extraocular eye muscles to allow for lateral movement of eye (Lateral rectus and retractor bulbi muscles)
|
Dysfunction results in:
inability to move eye laterally inability to retract globe resting medial strabismus |
|
|
Facial Nerve (VII)
|
Sensory (taste) to rostral 2/3 of tongue
Motor to muscles of facial expression, certain salivary glands, and lacrimal glands |
Assess by palpebral and menace (blinking) response, schirmer tear test
|
|
|
Vestibulocochlear Nerve (VIII)
|
Sensory to auditory stimuli and vestibular system
|
Assess by head tilt, vestibular ataxia, leaning
strabismus (positional, physiologic, spontaneous) hearing |
|
|
Glossopharyngeal Nerve (IX)
|
Sensory and motor to larynx, pharynx, certain salivary glands, + caudal 1/3 of tongue (taste)
|
|
|
|
Vagus Nerve (X)
|
Sensory and motor to larynx and pharynx (together with CN IX)
|
Asess with gag reflex, dysphagia, regurgitation
|
|
|
Accessory Nerve (XI)
|
Motor to trapezius, sternocephalicus, and brachiocephalicus m.
|
|
|
|
Hypoglossal Nerve (XII)
|
Motor to muscles of tongue
|
Asess tongue symmetry (deviation would be to ipsilateral side) and movement
|
