Front 3

where in the neck is the location of the buccopharyngeal fascia and the alar fascia?

Back 3

buccopharyngeal (a continuation of the pretracheal) connects the posterior aspect of the thyroid gland and lines the posterior aspect of the esophagus. The alar fascia connects the two carotid sheaths and is found between the buccopharyngeal fascia and the prevertebral fascia.

Front 4

the stylopharyngeus runs from the styloid process and travels between what two muscles? what innervates it? what is its action?

Back 4

it runs between the superior and middle pharyngeal constrictors. Innervated by glossopharyngeal. It raises the larynx and pharynx and facilitates swallowing.

Front 5

the styloglossus originates from the styloid foramen and travels where? what innervates it? what is its action?

Back 5

travels to the posterior aspect of the tongue. It is innervated by hypoglossal nerve. Together they retract the tongue. It also pulls up side of tongue to create a trough for swallowing.

Front 6

the stylohyoid is innervated by what nerve?

Back 6

the facial

Front 7

1. nasopharynx
2. oropharynx
3. laryngopharynx
4. aryepiglottic fold
5. epiglottic cartilage
6. palato-pharyngeal arch
7. salpingo pharyngeal fold
8. auditory tube
9. soft palate

Front 8

what is the main action of the pharyngeal muscles and what nerve innervates them?

Back 8

they constrict to move the bolus of food down. Vagus is the innervation

Front 9

what is origination, innervation, and action of the levator velli palatini?

Back 9

from the auditroy tube area, vagus nerve, and elevates the soft palate to prevent food from going into the nasal pharynx

Front 10

location, action, and innervation of the salpingopharyngeus?

Back 10

originates from the lateral part of the auditory tube and blends inferiorly with the palatopharyngeus. It draws the nasopharynx superiorly. Innervated by vagus

Front 11

general location, innervation, and action of the palatopharyngeus?

Back 11

lateral to the uvula. Vagus nerve. pulls pharynx and larynx up and toward the uvula when swallowing

Front 12

general location, innervation, and action of the stylopharyngeus?

Back 12

between styloid process and the pharynx. glossopharyngeal nerve. elevates pharynx and larynx and used in swallowing.

Front 13

the pterygomandibular raphe is located between what two muscles?

Back 13

the superior pharyngeal constrictor and the buccinator

Front 14

general location, innervation, and action of tensor veli palatini?

Back 14

lateral to the levator veli palatini in between the pterygoid plates. Trigeminal (mandibular nerve). Tenses the soft palate.

Front 15

what nerve provides autonomics to the mucous glands lining he pharynx?

Back 15

the vagus

Front 16

what nerve provides sensory information to the pharynx?

Back 16

glossopharyngeal

Front 17

what arteries supply the pharynx (give parent branches as well)?

Back 17

internal pharyngeal from superior thyroid, ascending pharyngeal from the external carotid, and the pharyngeal branches of the facial and lingual arteries

Front 18

what are the two recesses associated with the larynx and their positions?

Back 18

the vallecula posteriorly and piriform recess anteriorly.

Front 19

what does the epiglottis do during swallowing?

Back 19

it covers the glottis during folding to prevent food from going into the trachea.

Front 20

1. superior horn of thyroid cartilage
2. thyroid cartilage
3. inferior horn of thyroid cartilage
4. cricothyroid ligament
5. trachea
6. cricoid cartillage
7. ghost image of arytenoid cartilage
8. thyrohyoid membrane
9. epiglottis

Back 20

label

Front 21

why are the tracheal cartilage rings C shaped instead of the complete circle?

Back 21

for swallowing so the bolus from the esophagus can protrude into the trachea a bit.

Front 22

what aspect of the cricoid cartilage is thicker?

Back 22

the posterior aspect

Front 23

1. arytenoid cartilage
2. muscular process
3. vocal process
4. cricoid cartilage

Back 23

label

Front 24

what is the general location, innervation, and action of the cricothyroid muscle?

Back 24

it has 2 heads, the vertical (medial) and oblique (lateral) that arise from the lateral aspect of the thyroid cartilage and insert into the anterior aspect of the cricoid cartilage. The external laryngeal provides motor innervation while the recurrent laryngeal provides sensory info. It tenses the vocal cord to make high pitch noises.

Front 25

general location, innervation, and action of the transverse arytenoid muscle?

Back 25

inferior to aryepigglotic fold and superior to the posterior cricoid cartilage. innervated by the recurrent laryngeal nerve and it adducts the vocal cord to close the glottis between breaths.

Front 26

what is the general location, innervation, and action of the posterior cricoarytenoid muscle?

Back 26

on the posterior aspect of the cricoid cartilage. innervated by the recurrent laryngeal nerve. It abducts the vocal cord to open th glottis for breathing.

Front 27

general location, innervation, and action of the lateral cricoarytenoid muscle?

Back 27

supero lateral aspect of cricoid cartilage deep to the thyroid cartilage. It is innervated by the recurrent laryngeal and it adducts the vocal cord to close the glottis.

Front 28

general location, innervation, and action of the thyroarytenoid muscle?

Back 28

connects the arytenoid cartilage to the anterior aspect of the thyroid cartilage at the level of the vocal cord. innervated by recurrent laryngeal branch and it shortens the vocal cords for low pitch.

Front 29

the internal laryngeal branch of the superior laryngeal provides what?

Back 29

sensory info to the larynx above the vocal cord

Front 30

the recurrent laryngeal nerve provides what?

Back 30

sensory to the larynx below the vocal fold and motor to all intrinsic muscles of the larynx except the cricothyroid

Front 31

what nerve passes through a hole in the thyrohyoid membrane?

Back 31

the internal laryngeal nerve
