The mouth as a room
A read of this page, with the plate.
Teeth are a map of the entire body, like hands, feet, ears and irises. Each tooth has a meridian associated with it.


Class 9 is Unit II’s mouth. Course 08 named the jaw as fiber — masseter, pterygoids, temporalis. This hour holds the cavities those fibers close. Chart 9-1 is the plate: nasal cavity, oral cavity, pharynx in thirds, uvula, epiglottis, trachea in front, esophagus behind. Two doors. The flap chooses. Kapel’s board is a kitchen of names.
The job of this hour
Three jobs. Say them with me. Name the rooms. Walk the B-vitamin cascade as names. Name a tooth that has a history and hold it until Chart 9-5. Now what that actually means.
Name the rooms
Look at Chart 9-1. I want you able to point and say the name out loud. Nose room — nasal cavity. Mouth room — oral cavity, where chewing starts starch. Throat in three landings: above the soft palate, between palate and flap, then toward the voice. The little hanging drop is the uvula. The flap is the epiglottis — it shuts so food does not take the lung door. Air door in front: trachea. Food door behind: esophagus, collapsed until something is going down. If you cannot name the room, you are not in the mouth yet. Point. Name it.
Walk the B-vitamin cascade as names
The B vitamins on this board are a staircase. One step holds the next. You start at the floor: B-6. Then folate. B-12. Biotin. PABA. B-5. At the top: B-2, riboflavin — the corners of the mouth, a wrinkled upper lip. You walk those names in order. You do not jump to the top and call it a vitamin kit. If the top will not, you ask the step below. Names of a cascade. Not a scoop from a bottle.
Hold a tooth until 9-5
You already know an ear map and a hand map — a place on the body that parks a meridian. A tooth is that same kind of map. Each tooth has a meridian associated with it. The quote on the wall is Kapel’s: teeth are a map of the entire body, like hands, feet, ears and irises. Chart 9-5 parks those doors in hour 12. This hour you name one tooth that has a history — a filling, a crack, an absence — and you hold it. You do not read a parking you have not been given.
Practice
Do the three jobs in the lab. Job 1: point at Chart 9-1 and say three room names out loud. Job 2: walk the B-vitamin cascade with your finger, floor to top, and stop on one name. Job 3: name one tooth that has a history and hold it until 9-5. Journal the three names you spoke.
Check
This hour teaches the mouth as:
- A stomach bag that churns protein
- A room of cavities, a B-vitamin cascade walked as names, and a tooth held until 9-5 ✓
- A liver cell with two doors
Point. Name the room. Walk the B vitamins in order. Hold a tooth until Chart 9-5.
On Chart 9-1 the esophagus sits:
- In front of the trachea, always open, as the air door
- Behind the trachea, collapsed unless food is moving ✓
- Inside the nasal cavity
Two doors. Air in front. Food behind.
The epiglottis is:
- A salivary gland in front of the ear
- A flap of cartilage that shuts over the trachea so food does not take the lung door ✓
- A dose of a swallow
When you breathe it is open. When you swallow it shuts.
Pharynx on this plate is:
- One bag behind the liver
- The whole throat, then thirds: nasopharynx, oropharynx, laryngopharynx ✓
- Only the nasal cavity
Subdivided so Chart 9-1 can be read.
A uvula that is too low names:
- A small night airway — a room, not a mood ✓
- A dose of a snore
- Proof you skip the swallow
Air past a low uvula vibrates. Snoring that stops the breath belongs with a physician.
You use this hour in the work by:
- Parking every tooth on the spleen channel
- Naming the rooms, walking the B-vitamin cascade as names, holding a tooth until 9-5 ✓
- Starting the hour on a liver fair-and-future sentence
Three jobs. Rooms. B-vitamin cascade. A tooth held until the parking chart.
A tooth in this hour is:
- A dose of enamel
- A name you hold — Chart 9-5 parks the meridian in hour 12 ✓
- Proof you skip Chart 9-1
Same kind of map as ear and hand. The doors wait for 9-5.
The B-vitamin cascade on this hour is:
- A kit you dose
- Walked as names — interdependency, not a scoop ✓
- Only B-12
One step holds the next. You say the names. You do not scoop the top.
A swallow that will not, a night airway, an abscess:
- This hour’s dose
- A physician. You stop ✓
- A meridian you force
Doors out. The rooms stay named.
Chewing in the oral cavity starts:
- Protein with pepsin
- Starch with amylase — the rest of digestion waits ✓
- Fat with bile
The start is here. The bag and the scissors are later hours.
