4 histological layers of alimentary canal |
Mucosa - submucosa-Muscularis-Serosa/ Adventitia |
|
|
Explain Mucosa ? |
Mucosa : -Epithelium -Lamina Propria : LCT(loose conn tissue) + defence cells ( example Peyers patches in SI ) -Muscularis mucosae |
|
|
Explain Submucosa ? |
DCT ( dense connetive tissue) +Blood ,nerve, lymph vessel At this level absorption occurs |
|
|
Muscularis |
ussually inner: cicular outer longitudinal functional in peristaltic movement of food down the GI tract |
|
|
Serosa vs Adventitia |
IF a pre-existing Connective tissue is present its SEROSA because then its function is only function is lubrication If No Pre-existing Connective tissue ,then its Adventitia which functions as a Connective tissue Instead |
|
|
Accessory organs what are they and name them ? |
Organs Not Part of GI Tract ,however secrete into it. -Salivary glands -Liver -Gallbladder -Pancreas |
|
|
Number of Teeth , and its anatomy |
-20 -->32 permenant teeth -Anatomy: -enamel : Strongest component of body , more then bone , no vessels no nerve , thats why you dont feel pain when the caries start -Dentin: bulk bone like structure , can regenerate -Pulp : the Innermost component where we have Blood vessel Cementum :replaces enamel is the Root Tooth + Alveoli = Gomophore (Synarthroses ,Fiber) Periodental ligament. |
|
|
Oral Cavity ,topography , and function |
Topography: Superiorly :hard and soft palate Inferior: Glossus ( Tongue) Lateral: Buccinator ,Cheecks anterior: labia (lips) Posterior( oropharnyx) oropharnyx start with the UVULA and palatine tonsils lateral to it. Function : Mechanical Breakdown of food, by Teeth Chemical breakdown by saliva( amylase) which breaks down carbohydrates into sugar. |
|
|
Stomach Anatomy And function |
Anatomy : Cardia -fundus- Body -pylarus(PA+ PC) Function : Gastric juices digest protiens and Absorb Alcohol + drugs. Gastric juices( pepsin( chief cell)+ HCL (parietal cells) |
