Which muscle does the parotid duct cross
crosses masseter muscle
Which muscle does the parotid duct pierce
buccinators
Where does the parotid duct open into
oral cavity, maxillary 2nd molar
Where does the facial nerve run
Brain–>Internal acoustic meatus–> stylomastoid foramen–> Branches posteriorly into posterior auricular, chorda tympani (that travels with trigeminal nerve to tongue) and into temporal, zygomatic, buccal, mandibular, and cervical branches
Which nerve does the facial nerve travel with through the internal acoustic meatus
vestibular cochlear nerve
How does the facial nerve get to the tongue
The chorda tympani nerve of the facial nerve goes with the mandibular nerve branch of trigeminal nerve

periosteum (pericranium)
Where do the veins of the face arise from
Internal jugular
What connects the frontalis muscle and occipitalis in the back
the aponeurosis of the scalp
What layer allows for the transmission of emissary veins
loose areolar connective tissue (Come from dense connective tissue layer into superior sagital sinus)
What do emissary veins provide communication between
Between superficial veins of scalp and dural venous sinuses
What are the divisions of the trigeminal nerve
opthalamic, maxillary, mandibular
Which nerve is embedded in the posterior parotid gland and what is it a branch of
Auriculotemporal gland- branch of trigeminal
