Question 28

Laryngopharynx boundaries

Answer 28

superior epiglottis to inferior boarder of cricocartilage

Question 29

Cricothyroid m inn

Answer 29

external laryngeal n.

Question 30

Inferior constrictor m. inn

Answer 30

CN X

Question 31

Pharyngeal m. inn

Answer 31

CN X

Question 32

Cricothyroid m.

Answer 32

O: cricoid cartilage I: thyroid cartilage Inn: external laryngeal n. A: TILT thyroid cartilage anteriorly- TENSING vocal cords (produces higher pitches of phonation/voice) this muscle action causes the tilting/movement of the cricothyoid joint

Question 33

Posterior Cricoarytenoid m.

Answer 33

O: cricoid cartilage I: arytenoid cartilages Inn: inferior laryngeal n. (Recurrent Laryngeal N.) Action: OPEN glottis by abducting arytenoid cartilages (only mm to OPEN GLOTTIS)

Question 34

Arytenoid mm.

Answer 34

O: arytenoid cartilages I: arytenoid cartilage Inn: inferior laryngeal n. Action: close glottis by adducting arytenoid cartilages

Question 35

Lateral Cricoarytenoid m.

Answer 35

O: cricoid cartilage I: arytenoid cartilages Inn: inferior laryngeal n. Action: close glottis by adducting arytenoid cartilages

Question 36

Thyroarytenoid m.

Answer 36

O: thyroid cartilage I: arytenoid cartilages Inn: inferior laryngeal n. Action: Shorten & relax vocal cords

Question 37

Vocalis m.

Answer 37

Run parallel with the vocal cords, adjusting the tension of the cords for phonation Action: alter vocal cords during phonation/voice

Question 38

Rima glottis

Answer 38

leads to trachea

Question 39

Vestibular folds

Answer 39

False Vocal Cord -Sit on top of vocal fold (true vocal cord)

Question 40

Laryngeal ventricle

Answer 40

In between true and false vocal cord -Entry: laryngeal vestibule

Question 41

Superior laryngeal n.

Answer 41

Gives rise to internal & external laryngeal nn.

Question 42

Internal laryngeal n.

Answer 42

Pierces thyrohyoid membrane (watchdog) - Injury: sensory loss to superior larynx

Question 43

External laryngeal n.

Answer 43

runs superificial to cricothyroid m.

Question 44

Recurrent laryngeal n.

Answer 44

Circles aorta or subclavian - Becomes inferior laryngeal n.

Question 45

Inferior laryngeal n.

Answer 45

Runs posterior to cricothyroid joint - Gives inn to arytenoid vocal mm. - Inferior: ipsilateral injury to this nerve- paralyzes mm., therefore paralysis of the ipsilateral vocal fold (leads to hoarseness as vocal folds cannot meet in midline - Bilateral loss causes almost total loss of voice - Continuation of recurrent (name change at cricothyroid joint)
