Four functions of the larynx
Phonation, Conduction, Protection, Closure
VDphysical =
VDanat/2 + VDtube
VDanat = 2.2ml/kg
VDtube = 3.14 * r^2 * h
Cervical level of cricoid cartilage
C6
Crackling sound
Crepitus
Name the three components of the nasal septum
Perpendicular plate of the ethmoid, vomer, septal cartilage
Name the three phases of deglutination
Oral, Pharyngeal, Esophageal
When does the nasopharynx occlude during degluttition?
Pharyngeal phase
Function of the human airway
Protection, conduction, air conditioning (heat/humidification)
Innervation of the trachea
Vagus (CNX)
The eustachian tube connects what to what
Nasal cavity to middle ear
Horizontal displacement between teeth is called
Overjet
Vertical displacement between teeth is called
Overbite
How do you adjust the laryngeal axis of a patient?
Sheets
Putting sheets under a patient’s occipitus causes what action of the lower cervical vertebrae?
Flexion
what is responsible for first 50% of TMJ movement?
Inferior compartment (rotation)
what is responsible for the second 50% of TMJ movement?
Superior compartment (gliding)
Name the last constrictor muscle before food goes into the esophagus
Inferior pharyngeal constrictor
Order of axial alignment
LPO (Laryngeal, Pharyngeal, and Oral)
Fulcrum point
Hyoid bone
What instrument can cause epistaxis, laryngospasm, etc?
Nasal airway
Deglutition: oral phase
moistened food = bolus; tongue = trough; palataoglossal arches relax; moves to oropharynx
Deglutition: pharyngeal phase
nasopharynx occludes; larynx closes; breathing/coughing/sneezing/vomiting inhibited; hypopharynx rises; superior, middle, and inferior contrictors = peristalsis
Deglutition: esophageal phase
food moves to stomach; pharynx/larynx at rest
What surgical complication could cause vocal cord paralysis?
bilateral RLN damage
