Nasopharynx

Question 1

Location of nasopharynx

Answer 1

posterior to nasal cavity
superior to the soft palate

Question 2

Pharyngotympanic Tube

Answer 2

Also known as Eustachian Tube
- from torus tubarium to middle ear

Question 3

Adenoids

Answer 3

Pharyngeal Tonsils
- roof of the nasopharynx

Question 4

Torus Tubarium

Answer 4

bump in the nasopharynx

Question 5

Pharyngeal Constrictors

Answer 5

skeletal muscles

Question 6

Vagus Nerve

Answer 6

provides motor to all constrictor muscles EXCEPT STYLOPHARYNGEUS

Question 7

External Layer

Answer 7

constrict walls, elevate larynx
- made up of the superior, middle and inferior

Question 8

Internal Layer

Answer 8

elevate, shorten, widen pharynx during swallowing and speaking

Question 9

Recurrent Laryngeal Nerve

Answer 9

sensory below the vocal folds
- responsible for glottic closure

Question 10

Superior Laryngeal Nerve

Answer 10

Internal Branch: sensory above the vocal folds
External Branch: motor to cricothyroid muscle and inferior pharyngeal constrictor

Question 11

Sensation above and below the vocal folds

Answer 11

Vagus Nerve

Question 12

Damage to Vagus Nerve

Answer 12

effects superiror layrngeal nerve and recurrent laryngeal nerve

Question 13

Trigeminal Nerve

Answer 13

superior part of nasopharynx; anterior oral cavity

Question 14

Glossopharyngeal Nerve

Answer 14

Posterior Oral Cavity

Question 15

Pharyngeal Raphe

Answer 15

tendon; midline point of attachment for the constrictors on either side

Question 16

Superior Pharyngeal Constrictor

Answer 16

-pulls up thyroid and elevates larynx
-completes the area of the oropharynx posteriorly
-attaches to the greater horn of the hyoid, oblique line of the thryoid cartilage
-attatches posterior by the pharyngeal tubercle

Question 17

Stylopharyngeus

Answer 17

shortens and widens the pharynx when contracted; seperates the superior and middle constrictors
- ONLY EXCEPTION! innervated by the glossopharyngeal nerve

Question 18

Middle Pharyngeal Constrictor

Answer 18

constrict the pharynx to deliver food to esophagus; works in coordination with the superior and inferior constrictors
- Pathway: pharyngeal raphe; greater horn of the hyoid

Question 19

Inferior Pharyngeal Constrictor

Answer 19

constrict the pharynx to deliver food to the esophagus; works in coordination with supeior and inferior
-Pathway: pharyngeal raphe, goes anteriorly to the oblique line of the thyroid cartilage
- when contracted: larynx elevates

Question 20

Cricopharyngeus Muscle (UES)

Answer 20

prevents reflux of food from esophagus back into the throat
- most inferior part of the inferior constrictor

Question 21

Palatopharynges

Answer 21

shorten and widen pharynx and larynx during swallowing and speaking
- Pathway: soft palate to posterior pharyngeal wall
- Palatine Apenorousis: widen tendon of tensor veli palitini

Question 22

Salpingopharyngeus

Answer 22

• Tiny muscle of the soft palate
• elevate, shorten, widen pharynx during swallowing and speaking
• Pathway: from eustachian tube to lateral wall of pharynx
• Origin: styloid process of temporal bone
