## tympanic_membrane.jpg

The image is a detailed anatomical illustration of the tympanic membrane (eardrum) and related middle ear structures. The drawing is labeled with various parts of these structures.

### Key Elements in the Image:

1. **Tympanic Membrane:**
   - The central part of the eardrum is labeled as "Pars flaccida."
   - Surrounding this area, there are sections labeled as "Pars tensa," which refers to a more taut portion of the membrane.

2. **Middle Ear Structures:**
   - **Malleus (Hammer):** 
     - The head of the malleus is labeled.
     - The short process and long process of the malleus are also indicated, with the short process being the part that attaches to the tympanic membrane.
   - **Incus (Anvil):**
     - The body and short process of the incus are shown. 
     - The short process connects to the head of the malleus.

3. **Quadrants:**
   - The tympanic membrane is divided into four quadrants:
     - **Anterior-superior quadrant:** Located at the top front part.
     - **Posterior-superior quadrant:** Located at the top back part.
     - **Anterior-inferior quadrant:** Located at the bottom front part.
     - **Posterior-inferior quadrant:** Located at the bottom back part.

4. **Other Labels:**
   - "Cone of light" is shown, which represents the area where sound waves enter and are focused on the tympanic membrane.
   - The "Tympanic ring," a circular structure surrounding the eardrum, is also labeled.

5. **Additional Structures:**
   - The "Umbo" (the most prominent part of the malleus) is indicated as it protrudes into the middle ear cavity.

### Labels and Text:
- The labels are placed directly on or near each corresponding anatomical structure.
- The text at the bottom provides information about the source, stating that this figure is from "Kramer & Brown 2019 'Audiology: Science to Practice'" and credits Anson & Donaldson (1967) for the original work.

This image serves as an educational tool to help understand the anatomy of the tympanic membrane and its relationship with other middle ear structures.
