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

6.  Parotid
 Submandibular
 sublingual

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.

10.  Fertilzation:
union of two
gametes

12.  Blastomeres.The
zygote 2 daughter
cells

13.  3rd day of
development a
sloid ball of cell is
formed.
 16 cell.

14. Inner cell mass and outer cell mass. With fluid
filled cavity known as blastocoel.

15.  Formation of 2 germ layers

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)

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.

28.  Cleft palate
 Cleft lip
 combination

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.
