**Eye Anatomy: Key Components**

When studying the anatomy of the human eye, it's important to understand the various parts and their respective functions. Below is a detailed explanation of the key components that are critical for visual perception.

**Labelled Diagram:**

The accompanying diagram illustrates the cross-section of the eye, with specific parts labelled (A, B, C, D, E) corresponding to the list provided.

**Components:**

1. **A: Sclera**
- The sclera is the white outer layer of the eyeball. It provides structure and protection for the inner components of the eye.

2. **B: Choroid**
- The choroid is a layer containing blood vessels and connective tissue between the sclera and the retina. It's responsible for supplying nutrients and oxygen to the outer layers of the retina.

3. **C: Retina**
- The retina is a thin layer of tissue that lines the back of the eye on the inside. It receives light that the lens has focused, converts it into neural signals, and sends these signals to the brain for visual recognition.

4. **D: Fovea Centralis**
