General structures of the digestive system:
- Oral Cavity
- Pharynx
- Oesophagus
- Stomach
- Small intestine
- Large Intestine

Accessory Organs
- Teeth
- Tongue
- Salivary glands
- Liver
- Pancreas
- Gall Bladder

External Structures of the Mouth:
- Upper Lip (Labium Superior)
- Lower Lip (Labium Inferior)
- Oral Angle (Labial Commissure)
- Nasolabial Sulcus (Sulcus Nasolabialis)
- Philtrum
- Mentolabial Sulcus (Sulcus Mentolabialis)
- Oral Fissure (Rima Oris)

Division of the Oral Cavity:
- Oral Vesitibule (Vestibulum Oris)
- Oral Cavity Proper (Cavitas Oris Propria)

Oral Vestibule:
- External Borders: Lips and Cheeks
- Internal Borders: Teeth and Gums

Anatomy of the Lips:
- Frenulum of the Upper Lip (Frenulum Labii Superioris)
- Frenulum of the Lower Lip (Frenulum Labii Inferioris)
- Labial Glands (Glandulae Labialis)

Anatomy of the Cheeks:
- Buccinator Muscle (musculus buccinator)
- Buccopharyngeal Fascia
- Buccal Fat Pad (Bichat's Fat Pad)
- Layers of the Skin (cutis)
- Tunica Mucosa
- Parotid Duct (Ductus Parotideus)
- Papilla of the Parotid Duct (Papillae Ductus Parotidei)

Anatomy of the Teeth:
- Crown of the tooth (Corona Dentis)
- Root of the tooth (Radix Dentis)
- Neck of the tooth (Cervix Dentis)
- Periodontium
- Gomphosis (Dentoalveolar Joint)
- Dental Pulp (Pulpa Dentis)
- Root Canal (Canalis Radicis Dentis)
- Apical Foramen (Foramen Apicis Dentis)
- Dentin (Dentinum)
- Enamel (Enamelum)
- Cement (Cementum)
- Milk Teeth (Dentes decidui) 20 teeth, begins at 6th moth of life and ends at 24th month of life
- Replacement of milk teeth at age of 6-12 years
- Permanent Teeth (Dentes Permanentes) 32 teeth
- Wisdom teeth (dentes serotinus) appears at the age of 17-24 years

Tooth Arrangement:
PS! European way of arrangement
- First we divide the teeth into 4 equal quadrants
- First 2 teeth are called Incisor Teeth (Dentes Invisivi)
- Next teeth are Canine Teeth (Dentes Canini)
- Premolar Teeth (Dentes Premolares)
- Molar Teeth (Dentes Molares)
- 8*4=32 means we have 32 premanent teeth
- Milk Teeth have two incisor teeth, one canine tooth and two molar teeth

Anatomy of the Gums (Gingiva):
- Alveolar Mucus Membrane (Covers at the level of root of the tooth. Contains a lot of submucosal Connective tissue)
- Gum Proper (attached to the periosteum)
- Gingival Papillae (papillae gingivales)
- Gingival Margin (margo gingivalis)
- Gingival Sulcus (sulcus gingivalis)

Thank you very much this video was helpful in so many ways especially how you broke it down for better understanding how I wish this was how our professors at school teach.

[prof.sagheerzoology]

[BenadiBawanya]

Thankyou very much❤️super helpful video😊

[JUGNU.C.MEHROTRAPCBMBBS]

7:37 You forgot to add a few details such as the surfaces of the teeth(occulsal, lingual/buccal, lingual/Palatine, mesial, distal etc.) the types of teeth based on position(e.g.Anterior & Posterior or Maxillary & Mandibular etc.)and also dental formula, dental midline or quadrants and numbering systems of teeth(FDI, Zsigmondy, Universal etc.).Also periodontium = osseous tissue(bone)}
& neck is the CEJ(Cemento-enamel junction)BUT EXCELLENT VIDEO FOR REVISION !!!!(THANKS A LOT){Edited to thank}😅

[fritac]

Ayy new digestive system series! Looking forward to it!!

[kongkingjj]

i like this video so much, if u dont mind, i would like to ask can i have your permission to share this video to other website, sure, i will give the source of the original website, thank you very much

[debabratadas]

Please make video about development of digestive systems

[Antifragile_]

Your videos are all I was looking for
Amazing sir

[owoeyepaul]

And that my friend sounds like Dr Morgan, the Noted Anatomist.

[HomaShahnawaz]

Very Nice. Thank you so much. I learned a lot.

[ihsankhan]

That was really helpfull thanks for the lesson and playlis also :)

[ChamudiDharmakeerthi]

Thank you very much! This is really helpful

[katatoth]

hey. I have a gingival fibrous nodule below my lower 2nd tooth at the mucogingival junction.. it's a harder, white nodule, there are studies with pictures.. what do you think formed this? is the lymphatic system involved?
