What muscle does cranial for nerve four innervate?
Superior oblique muscle
Which modifiable risk factor most increases the relative risk of stroke? A. Smoking
b. hypertension
c. hypercholesterolemia
d. diabetes mellitus
B
Hypertension defined as systolic pressure greater than 165 mmHg or diastolic pressure greater than 95 mmHg increases the relative risk of stroke by a factor six. The Framingham study has confirmed that smoking is independently associated with stroke. The relative risk for heavy smokers (more than 40 cigarettes a day) is twice that of light smokers fear than 10 cigarettes a day. Cessation of smoking reverses the risk to that of non-smokers within five years of waiting. Hypercholesterolemia Has not been epidemiological linked to increased stroke incidence, but it’s strong influence on atherosclerosis makes it an indirect risk factor. Diabetes increases the relative risk of stroke by 3 to 6 times the general population
What muscle is innervated by cranial nerve six?
Lateral rectus
What cranial nerve innervates most of the ocular muscles?
Cranial nerve three
The mandibular nerve comes off of which cranial nerve?
5
Name the branches of cranial nerve seven
posterior Auricular. Nerve, tempororal branches , zygomatic branches, buccal branches, marginal mandibular branch, cervical branch
Branches of cranial nerve five
Ophthalmic, maxillary,
Mandibular
Describe lateral medullary syndrome
Also known as Wallenberg syndrome, PICA syndrome, or vertebral artery syndrome.
SX:
- ipsilateral findings: Horner’s syndrome, decreased pain and temperature in the ipsilateral face, cerebellar signs with characteristic falling towards the side of the lesion.
- contralateral findings: decreased pain and temperature sensation on the contralateral side of the body
- dysphasia, dysarthria, paralysis, vertigo, hiccups, and diplopia.
- There is no facial weakness
Horny Mark Wahlberg for the Horner’s syndrome falls (laterally) toward his lesion due to ataxia but can’t feel it because of no pain and temperature in his face.
Describe medial medullary syndrome
Medial medullary syndrome is the CVA of the medial medulla secondary to inclusion of the penetrating branches of the vertebral arteries or anterior spinal artery.
Rare with 1 to 2 cases Per 10 cases of lateral medullary syndrome
Signs and symptoms include ipsilateral hypoglossal palsy, contra lateral hemiparesis, and contralateral lemniscal sensory loss
What is the impairment with conduction a aphasia?
Impaired repetition with normal rate of speech, preserve comprehension. He’s in the arcuate fasciculus
What is the impairment with a anomic aphasia
Fluent speech, good comprehension, but difficulty with word finding along with aLexia and agraphia
What is the impairment with transcortical sensory Aphasia?
Fluent speech, without comprehension but preserved repetition
So I’m SENSING a transcortical good time making some pickled fuck repeat all kinds of shit.
What is the impairment with transcortical motor aphasia?
Non-fluent speech but good comprehension and preserved repetition
When forehead muscles are involved in a facial palsy is that lower motor neuron or upper motor neuron?
Lower motor neuron signifies lesion distal to the nucleus including four head and face
Upper motor neuron has forehead sparing.
