Answer 1

on internal jugular vein, at subclavian

Question 2

Phrenic Nerve

Answer 2

superficial on anterior scalene muscle, deep to subclavian vein

Question 3

Subclavian artery

Answer 3

sandwiched between anterior and middle scalene

Question 4

subclavian vein

Answer 4

anterior to the right and left anterior scalene muscles,

anterior to the phrenic nerve

Question 5

thoracic duct

Answer 5

anterior to anterior scalene on left side

Question 6

pterion components

Answer 6

greater wing of the sphenoid bone (anterior)
front bone (anterior and superior)
parietal bone (posteriorly and superiorly)
temporal bone (posteriorly and inferiorly)
middle meningeal artery

Question 7

scalp bleeding/infection spreading

Answer 7

not to neck–occipitalis to neck
not laterally–epicranial aponeurosis is continuous with temporal fascia
can spread anteriorly– frontalis enters supraorbital skin

Question 8
