Superficial structures Flashcards
Where does the facial nerve exit
The internal acoustic meatus and leaves the skull through the stylamastoid foramen
What does the fasial nerve anastomize to
To Zanzibar By Motorcar + cervical
Temporal: forehead and upper eyelid
Zygomatic: Infraorbital area, lateral area and upper lip
Buccal: Cheek, upper ip and corner of mouth
Mandibular: lower lip and chin
Cervical: platysma
General affarents (trigeminal) of face and neck include
Opthalmic division, maxillary division and mandibular division
Where does most of the blood supply of the face, scalp and superficial neck come from
external carotid artery
What are the branches of the external carotid artery
fascial artery occipital artery posterior auricular artery superficial temporal artery transervse fascial artery maxillary artery
what are the branches of the internal carotid artery
opthalmic artery lacrimal artery supraorbital artery anterior ethmoidal artery supratrochlear artery dorsal nasal artery
what are the tributaries to the internal jugular vein
fascial vein
superficial temporal vein
retromandibular vein
common fascial vein
what are the tributaries to the external jugular vein
posterior auricular vein
what does the pterygoid venous plexus receive blood from
recieve blood from superficial structures of the face through the maxillary vein, buccal, mental, and infraorbital veins
where does the cavernous sinus recieve blood from
superior and inferior opthalmic veins, angular, supra orbital and supratrochlear veins
what structures pass through the parotid gland
external carotid artery, retromandibular vein, and fascial nerve
What two structures pierce the buccinator muscle but dont innervate it
the parotid duct and the buccal nerve
General affarents from the parotid gland are carried mainly in the
auriculotemporal nerve and the great auricular nerve
what are efferents to the parotid gland
glossopharyngeal nerve
what are sialoliths
calcified deposits that block the parotid duct. Saliva builds up behind the blockage causing swelling. Pain worsened by swallowing, chewing or drinking
What are mumps
acute viral infection of the parotid glands…easily spread through saliva
where do the efferent of the face arise from
fascial nerve from fascial plexus
