Brainstem Part II Flashcards
Medial Medullary Syndrome is caused by a lesion to what?
Anterior spinal artery
Paralysis of one side of the body
Hemiplegia
Lateral Medullary Syndrome is caused by a lesion to what?
Posterior inferior cerebellar artery PICA
What is another name for Lateral Medullary Syndrome?
Wallenberg Syndrome
Which syndrome of the medulla affects the following structures: spinal trigeminal nucleus, lateral spinothalamic tract, vestibular nuclei, nucleus ambiguous, descending autonomic fibers, ICP?
Lateral Medullary Syndrome
Aka PICA Syndrome
aka Wallenberg Syndrome
This structure is a group of large motor neurons situated deep in the medullary reticular formation. It contains the cell bodies of nerves that innervate the muscles of the soft palate, pharynx, and larynx which are strongly associated with speech and swallowing.
Nucleus ambiguous
Which term means trouble articulating speech?
Dysarthria
Which vascular syndrome of the medulla results in ipsilateral loss of pain and temperature from the face, contralateral loss of pain and temperature from the body, vertigo, dizziness, nausea, vomiting, nystagmus, dysphasia, dysarthria, Ipsilateral Horner’s syndrome, Ipsilateral ataxic gait?
Lateral medullary syndrome
Bridge connecting cerebral cortex and cerebellum
Pons
Corticopontine fibers from the motor cortex synapse where?
Pontine nuclei
Pontocerebellar fibers run from the pons to the cerebellum through which structure?
Middle cerebellar peduncle
With Horner’s syndrome, will the pupils get larger or smaller?
Smaller
The ___ ___ is a nucleus in the pons of the brainstem involved with physiological responses to stress and panic
Locus coeruleus
A two neuron path which unites the cerebral cortex with the cranial nerve nuclei in the brainstem involved in motor functions
Corticobulbar tract
