28
→ Deciduous or milk teeth → 20 in number → Erupt from the 6th month up to the 6th year
Temporary teeth
29
→ 32 in number → Erupt from the 6th year up to 25th year
Permanent teeth
30
parts of teeth: hardest structure of the body secreted by ameloblasts
Enamel
31
formed by odontoblasts
Dentin
32
→ covers the dentin of the root → Secreted by cementocytes
Cementum
33
→ serve to attach the root of the tooth to the alveolar socke. → Dense connective tissue
Periodontal membrane
34
→ contains BV’s, N’s, fibroblasts, histiocytes, and LV’s
Pulp cavity
35
ALIMENTARY TRACT How many layers are there in the Alimentary tract?
4 layers in the whole stretch of the digestive tract:
36
Mucosa (ALIMENTARY TRACT)
o Epithelium o Lamina propria o Muscularis o Muscularis mucosae
37
Submucosa (ALIMENTARY TRACT)
o Submucosal gland o Blood vessel o Submucosal nerve plexus(Meissner’s plexuses) – for secretion
38
Tunica mucularis or Muscularis externa
o Inner circular layer o Myenteric nerve plexus (for motor or peristalsis – movement of your food along the digestive tract) o Outer longitudinal layer
39
The 2 Organs' glands that are at Lamina propia and submucosa
* Esophagus and Duodenum
40
MUCOSA of ESOPHAGUS
LE: SSNK (Stratified squamous non-keratinized/cornified)
41
Mucosa: Lamina propia of ESOPHAGUS

Smooth muscle
43
In submucosa, it has _______ for secretion
Meissner’s plexuses
44
characteristic feature of the esophagus

46
what muscle in Upper 1/3?
skeletal muscle
47
what muscle in Middle 1/3?
smooth and skeletal muscle
48
what muscle in Lower 1/3?
smooth muscle
