COMS 5553 KARA LYNN SIMUCASE
ASSESSMENT COMPREHENSIVE EXAM
STUDY GUIDE WITH COMPLETE
SOLUTIONS
●● What are the muscles involved in inspiration?
Answer: Diaphragm
External intercostal muscles: raise the ribs up and out
Serrates posterior superior: elevates rib cage
Levator costarium brevis: elevates rib cage
Levator costarum logies: elevates rib cage
●● What are the muscles involved in expiration?
Answer: Internal intercostal muscles
Latissimus dorsi
Rectum abdominis
Transverse abdominis
Internal oblique abdominal
Quadrates lumborum
●● What structures are involved in respiration?
,Answer: Lungs
Bronchi
Trachea
Spinal column
Sternum: manubrium, corpus, xiphoid process
Rib cage
●● What is the myoelastic-aerodynamic theory?
Answer: It's a theory of phonation. VF closure -> build up of sub glottal
air pressure -> pressure blows the folds apart -> folds vibrate -> air
moves through glottal opening, decreasing pressure -> folds sucked back
together.
●● What are the laryngeal cartilages?
Answer: Hyoid bone
Epiglottis
Thyroid cartilage
Cricoid cartilage
Arytenoids
Corniculates
●● Discuss the vocal folds, aryepiglottic folds and ventricular folds.
Answer: Vocal folds:
,They have three layers
Epithelium: the outer cover.
Lamina propia: the middle.
Vocalis muscle: the body
Aryepiglottic folds:
They go from arytenoids to larynx. Help preserve airway.
Ventricular folds:
Sometimes vibrate with low frequencies.
●● What are the intrinsic muscles involved in phonation?
Answer: internal thyroarytenoid: it's the primary portion of
thryoarynteoid muscles. it vibrates and produces sounds.
cricothyroid: lengthens and tenses vocal folds.
oblique and transverse arytenoid: contract and pull arynteoids together
for adduction.
posterior cricoarynteoid: abducts
lateral cricoarytenoid: adducts
, ●● What are the extrinsic muscles involved in phonation?
Answer: Elevators:
Digastric
Geniohyoid
Mylohyoid
Stylohyoid
Hyoglossus
Genioglossus
Depressors:
Thyrohyoid
Omohyoid
Sternothryoid
Sternohyoid
●● How many/what type of teeth do we have?
Answer: 32 teeth: 4 incisors, 2 canine, 4 premolar and 6 molar
●● What are the parts of the tongue?
Answer: tip, blade, dorsum, root and lingual frenulum.
