Cleft terms Flashcards
Tissues that form the primary palate and fuse by
sixth week of the embryonic period
Tissues that form the palate develop and fuse between
10-12 weeks of the embryonic and fetal periods.
Morphogenesis of the face and mouth
Normal development involves the merging and fusion of five processes to complete the formation of the primitive mouth and nasal cavities

Muscles of the Velum
Levator veli palatini-
Musculus uvulae
Tensor veli palatini: .
Palatoglossus:
Palatopharyngeus
- Horizontal fibers-move lateral pharyngeal walls toward midline and contribute to Passavant’s Ridge
- Vertical fibers-facilitate velar positioning
Levator veli palatini
- Velar elevation (up and back)
- Minor contribution in Eustachian tube opening.
Musculus uvulae
- elevation of the vertical fibers, creating a firm, bulky midline velopharyngeal seal.
- Only intrinsic muscle of the velum
Tensor veli palatini:
opens Eustachian tube
Palatoglossus:
- lower the velum
- Elevate the posterior portion of the tongue.
Muscles of the Pharynx
Superior Constrictor:
Salpingopharyngeus
Superior Constrictor:
Primary muscle responsible for lateral pharyngeal wall motion toward midline.
Salpingopharyngeus
may:
Influence lateral pharyngeal wall movement toward midline
Open Eustachian tube.
,aladaptive compensator error indicates what?
speech therapy is warranted not surgery.
This condition involves craniosynostosis, occasional midface hypoplasia, occasional upper airway obstruction, cleft palate, syndactyly, and developmental disability. The condition described is:

Limitations of this bottle include the atypical shape and the fact that the feeder must compress the bottle throughout the entire feed:
