Drag and label the parts of the ear in this interactive anatomy worksheet.

To solve the problem of labeling the parts of the ear in the provided image, let's carefully analyze the structure and match it with the given labels. Here is a step-by-step explanation:

Step 1: Understand the Ear Structure

The human ear consists of three main parts:
1. Outer Ear: Includes the pinna (external ear) and the ear canal.
2. Middle Ear: Contains the eardrum (tympanic membrane) and ossicles (three small bones).
3. Inner Ear: Includes the cochlea (for hearing) and semicircular canals (for balance).

Step 2: Identify Each Part in the Image

The image shows a cross-section of the ear with labeled boxes pointing to different parts. Let’s identify each part based on its location and function:

#### Top Left (External Ear)
- Pinna: The visible outer part of the ear that collects sound waves. It is the large, orange-colored structure at the top left of the image.

#### Middle Section (Ear Canal and Eardrum)
- Ear Canal: The tube that leads from the pinna to the eardrum. It is the narrow, orange-colored tube extending inward from the pinna.
- Eardrum (Tympanic Membrane): A thin, circular membrane at the end of the ear canal that vibrates when sound waves hit it. It is the light-colored, circular structure at the end of the ear canal.

#### Lower Middle Section (Middle Ear)
- Ossicles: Three tiny bones (malleus, incus, and stapes) that transmit vibrations from the eardrum to the inner ear. They are the small, grayish structures near the eardrum.

#### Bottom Right (Inner Ear)
- Cochlea: A spiral-shaped structure responsible for converting sound vibrations into electrical signals that the brain interprets as sound. It is the purple, coiled structure.
- Semicircular Canals: Three fluid-filled loops that help maintain balance by detecting head movements. They are the dark, looped structures near the cochlea.

Step 3: Match Labels to the Image

Now, let’s match the labels to the corresponding parts in the image:

1. Pinna: Top left (orange external structure).
2. Ear Canal: Middle section (narrow orange tube).
3. Eardrum: End of the ear canal (light-colored circular structure).
4. Ossicles: Below the eardrum (small grayish bones).
5. Cochlea: Bottom right (purple coiled structure).
6. Semicircular Canals: Near the cochlea (dark looped structures).

Final Answer

Here is the correct labeling for the image:

- Top Left Box: Pinna
- Middle Left Box: Ear canal
- Middle Right Box: Eardrum
- Bottom Left Box: Ossicles
- Bottom Right Box: Cochlea
- Far Right Box: Semicircular canals

Boxed Final Answer

\[
\boxed{
\begin{array}{ccc}
\text{Pinna} & \text{Ear canal} & \text{Eardrum} \\
\text{Ossicles} & \text{Cochlea} & \text{Semicircular canals}
\end{array}
}
