Head And Neck Flashcards
Nerves of the pharyngeal arches.
Mandibular nerve. Facial nerve. Glossopharyngeal nerve. Superior laryngeal nerve. Recurrent laryngeal nerve.
Branches of facial nerve.
Temporal. Zygomatic. Buccal. Marginal mandibular. Cervical.
Venous drainage of the head and face.
Supratrochlear vein + supraorbital vein + angular vein drain into facial vein.
Superior temporal vein and maxillary vein form the retro mandibular vein.
Anterior division of retro mandibular vein and facial vein drain into internal jugular vein.
Posterior division of retro mandibular vein and posterior auricular vein drain into external jugular vein.
Dangerous area of face, infection spreads by ?
Facial vein to angular and deep facial veins.
Angular -> superior ophthalmic veins -> cavernous sinus.
Deep facial vein -> pterygoid plexus -> emissary vein -> cavernous sinus.
