Pharynx And Larynx

Front 1

The pharynx is a continuation of which two systems?

Back 1

respiratory
digestive

Front 2

What are the three parts of the pharynx

Back 2

Nasopharynx
Oropharynx
Laryngopharynx

Front 3

What is the order/arrangement of the three parts of the pharynx?

Back 3

Nasopharynx is most superior
Oropharynx is in the middle and slightly anterior
Laryngopharynx is most inferior

Front 4

What are the boundaries of the nasopharynx?

Back 4

Superior: Posterior nasal choanae (opening)
Inferior: Soft palate/uvula

Front 5

What are the boundaries of the oropharynx?

Back 5

Superior: Soft palate/uvula
Inferior: Epiglottic cartilage

Front 6

What are the boundaries of the laryngopharynx?

Back 6

Anterior: Larynx
Superior: Epiglottic Cartilage
INferior: Cricoid Cartilage/C6 vertebrae

Front 7

What vertebral level is the cricoid cartilage found at?

Back 7

C6

Front 8

What are the two groups of pharyngeal muscles?

Back 8

circumferential (constrictors) 2
longitudinally (3)

Front 9

What do the constrictor muscles attach to?

Back 9

median raphe which attackes to the pharyngeal tubercle

Front 10

What are the anterior attachments of the superior pharyngeal constrictor?

Back 10

pteromandibular raphe
mylohyoid line of mandible
pterygoid hamulus

Front 11

What is special about the pteromandibular raphe?

Back 11

it does not attach at the midline

Front 12

What is the anterior attachment of the middle pharyngeal constrictor?

Back 12

stylohyoid ligament
greater and lesser horns of hyoid bone

Front 13

What is the anterior attachment of the inferior pharyngeal constrictor?

Back 13

Oblique line of thyroid cartilage
lateral surface of cricoid cartilage

Front 14

What passes through the gap superior to the superior constrictor?

Back 14

pharyngobasiliar fascia covers levator palati and auditory tube

Front 15

What passes between the superior and middle constrictors?

Back 15

stylopharngeus
glossopharyngeal

Front 16

What passes through the middle and inferior constrictors?

Back 16

internal laryngeal nerve of superior laryngeal of vagus
superior laryngeal artery of superior thyroid artery

Front 17

What passes under the inferior constrictor?

Back 17

recurrent laryngeal nerve of vagus

Front 18

What lies underneath the folds of the pharynx?

Back 18

the muscles they are named for

Front 19

What is in the posterior nasal pharynx?

Back 19

posterior nasal choanae
pharyngeal orifice of auditory tube/torus tubarus which turns into the salpingopharyngeal fold and behind it is the pharyngeal recess
the pharyngeal tonsils are up top

Front 20

What is in the oropharynx?

Back 20

palatoglossal fold from palate to tongue
palaotpharyngeal fold behind palatoglossal fold
palatine tonsils between the two folds
at pase of tongue there is the median glossoepiglottic fold and paired lateral glosoeppilottic fold
space between the median and lateral fold is the valleculae

Front 21

What is the piriform recess?

Back 21

When the pharynx leaves space on the lateral sides of the larynx in three places

Front 22

What three muscles elevate the pharynx in swallowing?

Back 22

the three longitudinal muscles of the pharynx palatopharynx, salphingopharynx, stylopharyngeus

Front 23

What causes food to not go into the trachea?

Back 23

Longitudinal pharyngeal muscles, stylohyoid and digastrics lift up entire pharynx and larynx and hyoid bone and push them against the epiglottis which is against the base of the tongue and trachea is blocked

Front 24

What is the function of the tensor palati and levator palati?

Back 24

tensor palati tenses palate so levator palati can lift palate so that it closes off the nasopharynx

Front 25

What is the origin of the levator palati?

Back 25

infratemporal suraface of temporal bone and medial aspect of cartilaginous auditoru tube

Front 26

what is the insertion of levator palati?

Back 26

tensor palati

Front 27

what is the origin of tensor palati

Back 27

scaphoid fossa and lateral aspect of cartilingeous auditory tube

Front 28

what provides motor innervation to all muscles of the pharynx with afew exceptions?

Back 28

vagus

Front 29

what are the exceptions to the motor innervation of the pharynx?

Back 29

stylopharyngeus - CN 9
tensor palati - CN V3 mandibular

Front 30

What provides sensory innervation to the superior aspect of nasopharynx?

Back 30

pharyngeal nerve of V2

Front 31

What innervates the rest of the pharyngeal mucosa?

Back 31

glossopharyngeal

Front 32

What innervates the entrace to the larynx?

Back 32

internal laryngeal nerve
