Question 10

this is how the clinical mind works

learn this - but don’t all out memorize it

just sounds like he mostly just wants us to know the four major causes (the ones on the left)

but still… figure it out…. yeah

Question 11

(Neuromuscular Oropharyngeal Dysphagias)

1-5. What are the five of these?

Matt Preheim loves hot buns

Answer 11

1. myasthenia gravis (Ach R Antibody)
2. polymyositis (muscle biopsy)
3. lupus myositis (anti-nuclear antibody)
4. hypothyroidism (TSH, T4/T3, TSH Stim)
5. brainstem disease (MRI, CSF)

stuff in parentheses is what is used to detect

Answer 12

1. CES relaxation
2. esophageal peristaltic contraction
3. GES relaxation simulated by swallowing

Question 13

1-2. Secondary peristalsis consists of what two things?

Answer 13

1. esophageal peristaltic contraction
2. GES relaxation stimulated by esophageal distension

Question 14

learn this - would be a good idea to watch this part of lecture

2nd lecture on 3/1 - around 3 minutes
