AND ANSWERS
What are Piaget's stages of cognitive development? - ANS Sensorimotor (0-2)
Preoperational (2-7)
Concrete (7-11)
Formal (11+)
What are the muscles involved in inspiration? - ANS 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? - ANS Internal intercostal muscles

,Spinal column
Sternum: manubrium, corpus, xiphoid process
Rib cage
What is the myoelastic-aerodynamic theory? - ANS 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? - ANS Hyoid bone
Epiglottis
Thyroid cartilage
Cricoid cartilage
Arytenoids
Corniculates
Discuss the vocal folds, aryepiglottic folds and ventricular folds. - ANS 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? - ANS 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? - ANS Elevators:
Digastric
Geniohyoid
Mylohyoid
Stylohyoid
Hyoglossus
Genioglossus
Depressors:
Thyrohyoid
Omohyoid
Sternothryoid
Sternohyoid
How many/what type of teeth do we have? - ANS 32 teeth: 4 incisors, 2 canine, 4 premolar
and 6 molar
What are the parts of the tongue? - ANS tip, blade, dorsum, root and lingual frenulum.
What are the intrinsic muscles of the tongue? - ANS 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? - ANS 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
What are the muscles of the pharynx? - ANS salpingopharyngeus: elevates laryngeal wall
stylopharyngeus: elevates and opens pharynx
superior pharyngeal constrictor: pulls wall forward
middle pharyngeal constrictor: narrows diameter or pharynx
inferior pharyngeal constrictor: constricts office of esophagus and reduces diameter of pharynx
What are the muscles of the soft palate? - ANS levator veli palatini: elevates velum
tensor veli palatini: tenses velum
palatoglossus: elevates and depresses velum
palatopharyngeus: lowers velum
What are the structures of the hard palate? - ANS Pre maxilla
Palatine process
