What is the time period for palate development?
|
From the 5th week to the completion of facial development
|
|
|
Front of the face is formed by
|
the nasal pit, the frontal nasal prominence, the lateral nasal prominence, the medial nasal prominence, and the maxillary prominence all move to meet together on top of the mandibular prominence
|
|
|
The forebrain grows into the
|
central frontal prominence
|
|
|
The Central frontal prominence grows into the
|
frontal nasal process
|
|
|
the frontal nasal process is divided into 2 parts. what are they?
|
the medial nasal process and the lateral nasal process
|
|
|
the lateral nasal process makes up what?
|
the sides of the nose and upper cheek
|
|
|
the medial nasal process makes up what?
|
center section of the nose, nasal septum, philtrum, the center of the upper lip and alveolar ridge and the premaxilla
|
|
|
the first part of the palate to form is called ____
|
the primary palate
|
|
|
the first part of the palate forms when the...
|
tissues from the fusion of the maxillary and medial nasal processes
|
|
|
The primary palate forms a partial division of the?
|
stomodeum into an upper and lower cavity
|
|
|
The primary palate fuses when?
|
5 and 6th week
|
|
|
Name the parts of the primary palate:
|
-the upper lip and philtrum
-upper 4 central and lateral incisors and underlying alveolar ridge -premaxilla (bone) -anterior nasal septum |
|
|
The secondary palate cannot form until:
|
a sudden spurt of growth in the mandibular arch causes the tongue to drop, where previously it was extended and high, filling up the oral cavity - now that there is space between the palatine processes, they can fuse together
|
|
|
The secondary palate closes from the _____ to the ______ in what direction?
|
incisive foramen, uvula, anterior to posterior direction
|
|
|
The secondary palate forms the
|
hard palate - posterior to the incisive foramen and the soft palate
|
|
|
The hard palate fuses between what weeks?
|
between the 6th and 10th week
|
|
|
the soft palate fuses between what weeks?
|
between the 10th and 12th week
|
|
|
Parts of the palate
|
-premaxilla
-incisive foramen -alveolor ridge -palatine process of maxilla -palatine bone -soft palate |
|
|
what part of the primary palate is formed first?
|
the premaxilla and incisive foramen
|
|
|
The ______________ is where the primary palate and seconday palate meet
|
incisive foramen
|
|
|
The seconday palate is formed when the
|
palatine processes come in from the sides and meet medially and 'zipper' down to the soft palate and the soft palate muscles zipper down and end at the uvula.
|
|
|
What are the types of Cleft abnormalities?
|
Cleft Lip
Cleft palate Cleft Lip and Palate Submucous Cleft |
|
|
A cleft lip only stops at the
|
incisive foramen
|
|
|
the cleft lip and palate is where
|
it keeps going from the lip to the incisive foramen down the midline
|
|
|
a cleft palate is where
|
the seconday palate has not completed formation
|
|
|
a submucous cleft is
|
where it looks complete, but there is only a lining of tissue covering the hole
|
|
|
Issues with a cleft lip
|
feeding, no suction, speech with labial sounds (b, p, m)
|
|
|
Issues with cleft palate
|
feeding issues, severe speech issues, hearing issues, multiple surgeries needed, air escape out the nose - unable to build pressue until surgery is performed successfully, can work with speech on position of speech sounds until surgery is performed if child is old enough
