Craniofacial Midterm Flashcards
Functions of Levator Palatine and Uvulus in Velar closure
Which muscles lift the velum during swallowing and non-nasal articulation
Levator and uvulus location
Uvulus is medial to levator muscles
Nasal septum composition
Nasal bone Perpendicular plate of Ethmoid bone Quadrangular septal cartilage Vomer Anterior nasal spine
Sagittal suture
Directly behind coronal suture, down the midline. Looks like an arrow.
Coronal suture
Fuses frontal bone, side to side on anterior aspect of skull
Labdoidal suture
Fuses occipital bone to parietal bones, laterally in posterior aspect of skull
Squamosal suture
holds temporal bones to parietal bones and occipital bones
Metopic suture
Not usually visible, issue in newborns, medial line in frontal bone
Fontanelle
Anterior junction of coronal, Saggital and metopic sutures, hole in skull
Posterior structure
juction of lambdoid and sagittal sutures
Columella
Separates nares
Vermillion
Colored part of lips
Philtrum
Channel between nose and lips
Bridge
nasal bone between eyes
ala
outer rim of nare.
Cupid’s bow
upper rim of upper lip
dorsum
upper ridge of nose, immediately inferior to bridge of nose
Philtral columns
ridges bordering philtrum
Maxilla
Forms the upper jaw- in two parts during gestation, fuse to one bone at 12 weeks 5 Processes: Zygomatic Frontal Alveolar Palatine Body
Nasal bone
Forms bridge of nose.
Sphenoid
Behind face, looks like a butterfly, boom of wings support soft palate
Palatine bone
L shaped bone on either side to form football goal
Attached to maxilla
Forms posterior 25% of hard palate
Comes to point to form posterior nasal spine (PNS)
Transverse suture joins palatine bone to maxilla
Vomer
Behind nose between eyes
Forms part of nasal septum
Nasal conchae
Formed in Ethmoid bone
covered in tissue that conditions air
