• 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.
• What are the intrinsic muscles of the tongue? -✓✓ANSWER: All innervated by
CN 12
Superior longitudinal muscle: shortens tongue. turns tip upward.
Inferior longitudinal muscle: shortens tongue. turns tip downward.
Transverse muscle: elongates tongue
Vertical muscle: narrows tongue
• What are the extrinsic muscles of the tongue? -✓✓ANSWER: All innervated by
CN 12
Genioglossus: forms bulk of tongue. retracts, draws tongue downward
Styloglossus: draws tongue up and back
Hyoglossus: retracts and depresses tongue
Chondroglossus: depresses tongue
Palatoglossus: elevates tongue and depresses velum
