Pharynx + Palate Anatomy Flashcards
vein on ventral surface of tongue
lingual vein
skin binding tongue to gingivae of lower incisor teeth?
Frenulum ‘tongue tie’
submandibular duct opening?
sublingual papilla
sublingual gland opening?
sublingual fold on floor of mouth
Parotid duct location?
parotid papilla of the buccal mucosa
Parotid gland innervation?
CNIX
Submandibular and sublingual gland innervation?
CNVII
Anterior 2/3 tongue innervation?
General sensory = CNV3
Special sensory = CNVII
Posterior 1/3 tongue innervation?
General + Special sensory = CNIX
Defects located in the midline migratory path of the thyroid?
thyroglossal duct cysts
4 tongue muscles
Palatoglossus Styloglossus Hyoglossus Genioglossus -function to positon during mastication, swallowing and speech
Clinical testing of CN XII?
stick tongue out
Tongue tip @ midline if both CN XIIs functioning
TOngue points towards side of injured nerve if unilateral CN XII damage
Blood supply of tongue?
Lingual artery branch of external carotid
laceration of vermillion border?
refer to plastic surgeon
classic tonsil also known as ?
palatine tonsil
division of hard palate?
median palatine suture
Skeletal muslces of soft palate innervated by ….
CNX
except tensor veli palatini (CNV3)
Clinical testing of CNX + CNV3
Ask patient to say ‘aaaah’
Uvula should lift straight up midline
Unilateral nerve pathology, uvula will be pulled away from the non functioning side
Longitudinal muscles of pharynx?
Stylopharyngeus [CNIX]
Palatopharyngeus [CNX]
Salpingopharyngeus [CNX]
(all elevate pharynx + larynx)
Waldeyer’s RIng of lymphoid tissue:
Adenoid tonsil (roof of nasopharynx) Tubal tonsils (eaustachian opening) Palate associated lymphoid tissue (soft palate) Palatine tonsil Lingual tonsil (posterior 1/3 tongue)
