Question 24

Clinical significance of Emissary V

Answer 24

it drains the scalp into the superior sagittal sinus, so infections on the scalp can spread there (ex. meningitis)

Pterygoid Plexus clinical significance

Answer 28

it acts as a peripheral pump so by yawning/opening your mouth it sends blood through maxillary

N is over it, and A is under it

*A feeds sublingual gland and oral floor with sublingual branch; base of tongue with deep

Question 30

Vertebrobasilar Insufficiency

Answer 30

due to not enough blood getting to brain bc of Vertebral a. occlusion/quick motion
