ACCURATE SOLUTIONS
◉ What are the muscles involved in inspiration? Answer: Diaphragm
External intercostal muscles: raise the ribs up and out
Serratus posterior superior: elevates rib cage
Levator costarum 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
