Craniofacial Vasculature (extra) Flashcards
Arterial supply to meninges
ECA –> middle meningeal a. (enters foramen spinosum) –> frontal a. (ant) and parietal a. (post)
Innervation of meninges
V1
V2
V3
Cervical spinal nerves
Most venous drainage from head an neck drains to:
IJV
What does inferior petrosal v. drain?
Cavernous sinus
How is the facial v. formed?
Supraorbital v. and Supratrochlear v. form the angular v. which becomes facial v.
How is the pterygoid plexus joined to the facial v.?
Deep facial v.
How is the cavernous sinus joined to the facial v.?
Superior ophthalmic v.
What forms the retromandibular v.?
Maxillary v. and superficial temporal v.
Anterior division of retromandibular v. joins:
Facial v.
Posterior division of retromandibular v. joins:
Posterior auricular v. to make EJV.
How is maxillary v. formed?
Confluence of veins from pterygoid plexus
Who drains pterygoid plexus if maxillary v. is occluded?
Deep facial v.
Where do pharyngeal vs. drain?
IJV
Facial v.
Lingual v.
Superior thyroid v.
Occipital v. drains into:
Usually vertebral v. or posterior auricular, but can be IJV
Where does middle thyroid v. drain?
IJV
Where does superior thyroid v. drain?
Facial v. or IJV
What artery supplies the sublingual gland and oral floor?
Sublingual a.
What supplies the base of the tongue AND runs w/ lingual v.?
Deep lingual a.
Orientation of artery and nerve to hyoglossus m.
Lingual n. is superficial to hyoglossus m. and lingual a. is deep to hyoglossus m.
What nerve does occipital a. travel with?

What are greater and lesser palatine as. branches from?
Descending palatine a. from pterygopalatine part of maxillary a.
Greater palatine a.: hard palate
Lesser palatine a.: soft palate and palatine tonsil
Branches of superficial temporal a.
Transverse facial a. Middle temporal a. Anterior auricular a. Frontal a. Parietal a.
Where does superficial temporal a. begin?
Where does it terminate?
