landmark where coronal and saggital sutures meet between the two parietal bones and frontal bone
landmark where the lambdoidal suture meets the saggital suture
highest part of the skull. not really sure what he means by that
mushroom areas of dura that etch into the bone where the arachnoid granulations sit
superior saggital sinus connects to?
lateral venous lacuna
what should you pay attention to when you study foramina?
What bone are they in? are they at a bony junction?
"goes from the front to the back" of the skull and it is the origin of the occipitofrontalis frontal body, auricularis superior, occipitofrontalis occipital belly. ALL these are innervated by CN VII
layers of scalp?
Skin, Connective tissue (dense), Aponeurosis, loose areolar tissue, bone. blood vessels tend to run in subQ
, What is Diploe
the spongy bone in the middle layer of the skull. it gets thicker or thinner based on muscle attachments
t/f superior saggital sinus is beneath the dura
primary sensory nerve of scalp?
which word should you be able to spell?
Which trigeminals are purely sensory
where is the trochlea?
trochlear is a pully on the inside of the orbit that a muscle goes around. thats why the V1 nerve has supratrochlear, infratrochlear branches
inside your orbit ____comes off V2
zygomatic and splits to z.temportal and z.facial
back of head (behind ear) is innervated by?
spinal nerves from cervical plexus. don't forget that C1 doesn't have a dermatome
if you get a tattoo behind your ear, which nerve will relay that pain

outer part of dura, adjacent to the bone is technically not dura. what is it, and what is it called?
its periosteum and its called the periosteal layer of dura. the true dura is the meningeal layer of the dura
where does the periosteal layer of dura end?
