3. Muscular and largest
single organ in the
mouth
Anterior 2/3 located
in the floor of the
mouth
Posterior 1/3 in the
pharynx
Divided antero
porterior by the
sulcus terminlis.
Divided into anterior
lateral halves by the
lingual septum
4. Filiform papilla: numerous, pointed, cone
shaped
Fungiform papilla: mushroom shape
Foliate papilla: are narrow mucosal flds
bilaterally located along the posterior border
of the body about 4 to 8 in number. Well
developed at birth and became atrophied in
mature individual
Vallate: largest papilla. 8 to 10 in numbers.
Arranged in v-shape manner.
5. Masses of lymphoid tissue with the primary function of producing lymphocytes and
has a role in immunization
4 in numbers. And formed the protective ring of waldeyer
Palatine tonsils, lingual tonsils and pharyngeal tonsils
7. Clinical crown
Anatomical crown
Anatomical root
(covered by
cementum)
Clinical root (
implanted and
surrounded by the
periodontium
8. Enamel: hardes calcified tissue covering the
anatomical crowns of teeth
Dentin: main bulk of the tooth underneath the
enamel and cementum
Cementum: calcified tissue that covers the
anatomical root
Alveolar bone: part of the jaw that forms the
alveolar socket where the tooth is embeded
Gingiva: a firm mucosa around the neck of the teeth
Periodontal ligament is the fibrous connective tissue
found between the roots of the teeth and alveolar
bone.
18. Human facial development begins at
approximately four weeks post conception
with the appearance of the five processes,
which surrounds the early oral cavity or the
so called STOMODEUM.
Frontonasa process
Maxillary process (paired)
Mandibular process (paired)
19.
20. Development of the frontonasal process
rapidly enlagres as the underlying forebrain
expands into bilateral cerebral hemispheres
Themandibular processes unite to provide
continuity to the forbearer of the lower jaw
and lip.
21. Medialand lateral nasal processes from
within the enlarge frontonasal process to
surround an early ectodermal thickening, the
nasal placode.
22. Medial growth of the maxillary processes
dominates subsequent development of the
face resulting in contact then fusion with the
lateral nasal processes.(forming nasolacrimal
duct, cheek and alar base of future nose)
23. Further growth towards the midline pushes the lateral nasal
processes superiorly and allows fusion of the maxillary
processes with the medial processess inferiorly merging them
together in the midline to form:
Central portion of the nose, upper lip philtrum and primary
palate.
24. The palatine shelves are forming from the maxillary
processes and are directed downward on each side of the
developing tongue.
25. Thetongue has been depressed and the
palatine shelves are elevated but not fussed.
26. Fusion
of the shelves and the nasal septum is
completed.
29. Clefts of the lip and clefts of the palate can
occur simultaneously or separately.
Identify as primary or secondary.
The primary palate includes: Lip and
Alveolus
The secondary palate includes: Hard
palate, Soft palate, Uvula
30. Any cleft of the primary or secondary palate
may
be complete or incomplete, depending on whether
or not the cleft involves the entire anatomic
structure.
Any cleft of the primary or secondary palate may
be unilateral or bilateral.
Submucous clefts of the secondary palate may also
occur.
