buccinator nerve

transversley elongated condyle of auricular surface of mandible

styloglossus muscle - run from styloid to tip of tongue

genioglossus msucle - within frenelum

geniohyoid muscle - run from genu of mandible to body of hyoid apparatus

sternohyoid muscle - from sternum to body of hyoid

sternothyroid muscle - from sternum to thyroid cartilage of larynx

vallate papillae - 2 thirds of the distance between tip of tongue and epiglottis

conical papillae - on caudal 1/3 of tongue

foliate papillae - on side of caudal 1/3 of tongue

what marks the tongue midline

median sulcus

stylopharyngeus muscle - styloid bone of hyoid apparatus to wall of pharynx

• dilates pharynx

• I = glossopharyngeal nerve

laryngopharyngeus muscle - from larynx over pharynx

constrictor of pharynx

I = glossopharyngeal and vagus nerve

pterygopharyngeus muscle - pterygoid process then run caudally under hyoid bones and insert on pharynx

shortens harynx when swallowing

I = glossopharyngeal and vagus nerve

levator veli palatini muscle - near pterygoid process and insert on soft palate

elevates soft palate during swallowing
