  1. Middle meningeal artery
    • branches off internal maxillary branch of external carotid artery --> through infratemporal fossa --> foramen spinosum --> middle cranial fossa
    • -supplies meninges, dura mater
  2. Inferior alveolar artery
    • branches off internal maxillary branch external carotid artery --> through mandibular foramen --> in mandible
    • -supplies mandible, gums and teeth
  3. Chorda tympani
    • nerve that branches off CN7 (facial)-> through petroympanic fissure -> infratemporal fossa and joins lingual nerve of CN5
    • -sense tase from anterior 2/3 of tongue
  4. GSPN
    • Greater superificial petrosal nerve
    • branches off the geniculate ganglion of CN7 -> goes through the facial hiatus then the foramen lacerum (where it is joined by the Deep Petrosal symapthetics) -> vidian canal -> pterygopalatine fossa -> synapses on pterygopalatine ganglion
    • -parasympathetic innervation of lacrimal glands and mucosal glands
  5. Surroundings of middle meningeal arteries
    • 1. Runs beneath the pterion (v. vulnerable to injury)
    • 2. auricotemporal nerve wraps around it in the infratemporal fossa (the location of the otic ganglion)
  6. Two terminal branches of the external carotid artery
    • 1. superifical temporal artery
    • 2. internal maxillary artery (--> middle meningeal artery)
  7. Inferior alveolar branch of the mandibular nerve
    • from CNV3 (mandibular) through the foramen ovale -> inferior alveolar branch -> through mandibular foramen -> out the mental foramen
    • -innervates lower teeth and inside and outside of lip
  8. Three important anterior branches of the external carotid artery that form at the neck region?
    superior thyroid artery, lingual artery, and the facial artery
  9. SCALP?
    • skin-outer epidermis layer
    • connective tissue-fibrous layer
    • aponeurosis epicranialis-tough protective layer that anchors the superficial layers of the scalp
    • loose areolar tissure-vascular layer with losts of collagen
    • periosteum (pericranium)-inner vascular tissue covering the skull bones (allows for bone repair and nutrient supply)
  10. Tonsils?
    • -lymph nodes surrounding the throat, part of immune system and protect against infection
    • -pharyngeal (in nasopharynx), paired palatine (both sides of soft palate), and lingual tonsils (at posterior third of tongue)
    • -drain into deep cervical lymph nodes
    • -innervated by CNIX (glossopharyngeal)
