craniofacial book questions ch.1-6 exam
Why is it important to understand normal structure when working with individuals
with a history of cleft lip and palate? - You must first understand what normal
looks like in order to identify and treat abnormal appropriately
What are the facial landmarks and structures that may be relevant to the study of
cleft lip? - Philtrum- long dimple that courses from columella down to upper lip
Philtral ridges- borders philtrum; embryological suture lines that are formed as
segments of the upper lip form
Cupid's bow- top of upper lip
Labial tubercle- upper lip, inferior border of midsection of vermilion; somewhat
prominent point
White roll- border tissue that surrounds lips
Vermilion- skin of lip; darker than rest of face
Orbicularis oris- muscle that encircles mouth
,craniofacial book questions ch.1-6 exam
Describe the internal nasal structures and the various functions of the nasal
turbinate's - pyriform aperture
nasal septum
quadrangular cartilage
Vomer
Nasal turbinate's
what is the pyriform aperture? - pear shaped opening to bony inside of nose;
bordered by nasal and maxillary bones
what is the nasal septum? - located in midline of nose and serves to separate
nasal cavity into two nostrils
what is the quadrangular cartilage? - forms the anterior nasal septum and projects
anteriorly tot columella
what is the vomer? - trapezoidal shaped bone in nasal septum positioned
perpendicular to palate
,craniofacial book questions ch.1-6 exam
what are nasal turbinates? - paired bony structures within nose that are covered
with mucosa
Attached to lateral walls of nose and protrude medially into nasal cavity
Long, narrow, shelf-like and curled in shape
As air flows underneath them, the curled shape helps to create turbulent airflow
to maximize contact of the inspired air with the nasal mucosa
what are the 3 functions of the nasal turbinates? - 1) Mucus that covers the nasal
mucosa filters inspired air of gross contaminants by trapping particulate
contaminants
2) The turbinate's warm and humidify the inspired air
3) Turbinate's deflect air superiorly in the nose in order to enhance sense of smell
what are the oral structures that can be seen when looking in the mouth? - faucial
pillars
, craniofacial book questions ch.1-6 exam
tonsils
hard palate
alveolar ridge
velum/soft palate
tongue
teeth
what are the faucial pillars? - back of the oral cavity; both anterior and posterior
faucial pillars contain muscles that assist with velopharyngeal movement
how many tonsils are there? - 3 (palatine, lingual, pharyngeal)
what is the hard palate? - bony structure that separates oral cavity from the nasal
cavity; serves as both roof of mouth and floor of nose
what is the alveolar ridge? - anterior portion of hard palate; forms bony support
for teeth
what is the velum/soft palate? - back of the mouth and attached posterior border
of hard palate; consists of muscles
