Pharynx

Question 1

Pharyngeal tonsil

Answer 1

located in the pharyngeal recess
adenoids-enlarged inflamed pharyngeal tonsils
can obstruct nasopharynx, can spread to tubal tonsils impairing hearing and can ever spread to middle ear causing otitis media

Question 2

Salpingopharyngeal fold

Answer 2

fold of mucosa ovelyting salpingopharyngeus m.

runs down from Torus tubarius

Question 3

tubal tonsil

Answer 3

lymphoid tissue located near th opening of the auditory tube (torus tubarius)

Question 4

Salpingopharyngeus m.

Answer 4

runs from cartilage of auditory tube and runs down to thyroid cartilage
assists other mm with swallowing
innervated by vagus

Question 5

fauces

Answer 5

passageway from mouth to oropharynx

Question 6

palatoglossal m

Answer 6

fold of mucosa over palatoglosssus is the arch

from soft palate to tongue
pulls tongue and soft palate together during swallowing
Closes teh fauces

Question 7

palatopharyngeal m.

Answer 7

from soft palate to the thyroid cartilage
innervated by vagus
swallowing

Question 8

tonsillar bed

Answer 8

deepresion bw palatoglossal and palatopharyngeal folds

formed by superior constrictor, hyoglossus, middle constrictor

Question 9

epiglottic valleculae

Answer 9

depressions b/w the epiglottis and posterior tongue formed by lateral and median glossoepiglottic folds (membranes that connect the posterior tongue to the palate)

Question 10

piriform recess

Answer 10

depression lateral to larynx
internal laryngeal n. runs deep to mucosa of the piriform recess

**if a swallowed object damages the mucosa of the piriform recess it can damage the internal laryngeal n. (think fish bones)

Question 11

fascias of pharynx

Answer 11

pharyngobasilar fascia lines the inside of all muscles while buccopharyngeal covers the external layer of muscle

Question 12

Superior constrictor

Answer 12

circular oriented m. forming superior portion of phayrnx
attaches to skull
swallowing
n: vagus via pharyngeal plexus

Question 13

middle constrictor

Answer 13

runs from middle pharynx to the hyoid
swallowing
n: vagus via pharyngeal plexus

Question 14

inferior constrictor

Answer 14

runs from inferior pharynx and attaches to the thyroid and cricoid cartilages
swallowing
n: vagus via pharyngeal plexus

Question 15

Stylopharyngeus

Answer 15

from styloid to thyroid cartilage
swallowing
CN IX

Question 16

Salpingopharyngeus

Answer 16

from cartilage of auditory tube to the thyroid cartilage
swallowing
CN X

Question 17

palatophayngeus

Answer 17

from hard and soft palate to the thyroid cartilage
swallowing
CN X

Question 18

Gap 1

Answer 18

bw base of skull and sup constrictor

allows for passage of levator veli palatini and auditory tube

Question 19

Gap 2

Answer 19

bw superior and middle constrictors

allows for passage of stylopharyngeus and glossophayngeal n.

Question 20

gap 3

Answer 20

bw middle and inf constrictors

allows for passage of internal laryngeal n. and superior laryngeal a.

Question 21

gap 4

Answer 21

bw inf constrictor and esophagus

allows for passage of inf (recurrent) laryngeal n. and a.

Question 22

pharyngeal n. plexus

Answer 22

SVE of vagus n. (except SP)
GVA of IX
SNS fibers from cervical chain
***Gag reflex (in by IX (GVA) and out by X (SVE))
