Unit 3 last lecture

Question 1

three parts of pharynx

Answer 1

top to bottom
nasopharynx (behind nose)
-aka superior pharyngeal constrictor

oropharynx (back of mouth)
-aka middle pharyngeal constricter

laryngopharynx (under back of mouth)
-aka inferior pharyngeal constricter

Question 2

where is the pharynx located

Answer 2

at the end of the nasal cavity

Question 3

Inside the Nasopharynx/ superior pharyngeal constrictor

Answer 3

Opening of the Auditory (Eustachian) Tube
Tubal Elevation (Torus Tubarius

Question 4

Eustachian tube connects

Answer 4

middle ear to nasopharynx

-sometimes in younger kids theirs a tubal tonsil

Question 5

Eustachian tube lateral 1/3rd is ___ medial 2/3rd is ___

Answer 5

lateral 1/3 is bone

medial 2/3 is cartilage

Question 6

Pharyngeal Tonsil or “Adenoid is found in

Answer 6

pharynx

Question 7

The pharynx helps us swallow food by

Answer 7

pharynx constrictors- think the cups stacked

Question 8

Cricopharyngeus

Answer 8

acts as a sphincter at bottom of pharynx. Relaxes to let you swallow, if its contracted food won’t be able to go down

Question 9

Waldeyer’s tonsillar ring -

Answer 9

consists of tonsillar tissue surrounding the entrance to the pharynx
top of square = pharyngeal tonsil (back of throat)
two sides of mouth = palatine tonsils
bottom of square, post part of tongue= lingual tonsil

Question 10

Cricoid -

Answer 10

lies below the thyroid cartilage and shaped like a signet ring, with the expansion turned posteriorly (hyaline cartilage

Question 11

Epiglottis

Answer 11

• leaf-shaped, lies behind and below the tongue. Covers entrance to larynx. The epiglottis is composed of fibroelastic cartilage, and when swallowing, descends to cover the entrance way anteriorly into the larynx, or superior laryngeal inlet. Several attachments of the epiglottis should be noted

Question 12

Median and lateral glossoepiglottic folds -

Answer 12

attach the epiglottis to the root of the tongue

Question 13

Hyoepiglottic Ligament

Answer 13

attaches the epiglottis to the hyoid bone. When swallowing occurs, the hyoid is elevated, creating a “fulcrum” effect around the hyoepiglottic attachment, which in turn causes the epiglottis to descend and cover the glottis

Question 14

which muscles lift your hyoid bone when swollowing

Answer 14

supra hyoid muscles

Question 15

which muscles descend your hyoid after swollowing

Answer 15

infra hyoid muscles

Question 16

Thyroepiglottic ligament -

Answer 16

attaches the epiglottis to the thyroid cartilage, is a hinge

Question 17

Rima Glottis

Answer 17

Space between the vocal ligaments

Question 18

Glottis:

Answer 18

Space plus the true vocal ligaments

Question 19

abduction of glottis

Answer 19

opening of voice box.

Question 20

Vestibular (false) vocal folds -

Answer 20

these are in the upper portion of the larynx and are immobile. The opening between these folds is called the rima vestibuli.

Question 21

Vocal (true) vocal folds - these are below the vestibular folds and are mobile and contain

Answer 21

vocal ligaments

Question 22

The opening between the true folds is called the rima glottidis. There is a recess, or sinus, found between the vocal and vestibular folds. The true vocal folds and the open space between them are called the ___. It is inside the larynx.

Answer 22

glottis
