Fossa pterigopalatina — communication?
Connects nasal cavity, orbit, infratemporal region.
Nervul facial — segment timpanic?
Located near the middle ear cavity.
Canalul facial — pathway?
Runs through the facial canal from the internal acoustic meatus to stylomastoid foramen.
Ramuri intrapietroase — nerves?
Nervul timpanic, chorda tympani, stapedius nerve.
Ramuri extrapietroase — territories?
Innervate head muscles, glands, and sensory areas via cervical and thoracic branches.
Nervul glosofaringian — origin?
Emerges from the medulla, exits jugular foramen.
Nervul vag — origin?
From medulla, exits jugular foramen, gives cervical, thoracic, abdominal branches.
Ramuri cervicale vag — function?
Innervate muscles and viscera of the neck.
Nervul nazociliar — role?
Provides sensation to the nasal cavity and skin of the nose.
V1 — terminal branches?
Lacrimal, frontal, nazociliar nerves.
V2 — pathway?
Enters foramen rotundum, then via fissure and infraorbital nerve to face.
V2 — main branches?
Zygomatic, infraorbital, superior alveolar nerves.
Nervul mandibular — branches?
Auriculotemporal, lingual, inferior alveolar nerves.
Nervul auriculotemporal — course?
Encircles middle meningeal artery, supplies ear and temple.
Nervul lingual — innervation?
General sensation to anterior 2/3 of tongue.
Nervul maxilar V2 — function?
Sensory to midface, maxillary teeth, palate.
Nervul trigeminal V — divisions?
V1 (ophthalmic), V2 (maxillary), V3 (mandibular).
Nervul vag — recurrent laryngeal?
Loops around aortic arch (left) or subclavian artery (right), ascends to larynx.
Vagus — parasympathetic targets?
Heart, lungs, digestive tract, and abdominal organs.
Nervul glosofaringian — sensory territory?
Posterior tongue, pharynx, middle ear, carotid sinus.
Nervul vag — terminal branches?
Anterior and posterior vagal trunks, innervate thoracic and abdominal organs.
Nervul trigeminal — V1 vs V2?
V1: sensation from forehead, eye; V2: sensation from midface, maxilla.
