1. meningeal layer (to tissue)
2. periosteal layer (to the skull)
The area in between the two is sinus where vein can travel.
What is the role of the otic ganglion? → glossopharngeal (CNIX) sends preganglionic parasymphatetics to the parotid gland.
What muscles responsible for extortion and intorsion of the eye? → Extorsion: Inferior oblique and rectus
Intorsion: Superior oblique and rectus
Explain the structures in the cavernous sinus. → Down posterior through superior saggital sinus of the falx cerebri. then through the transverse sinus of the tentorium cerebelli. then to the internal jugular vein.
What is the role of the geniculate ganglion? → glossopharngeal (CNIX) sends preganglionic parasymphatetics to the parotid gland.
