In which layer of eyeball dense connective tissue is present ?

Options

A. Choroid layer
B. Neurosensory layer
C. Sclerotic layer
D. At Fovea

Answer

### Step-by-Step Solution:

1. **Understanding the Layers of the Eyeball**: The eyeball consists of three main layers: the outer layer (sclera), the middle layer (choroid), and the inner layer (retina). Each layer has distinct characteristics and functions.

2. **Identifying the Layers**:
- **Sclera**: This is the outermost layer of the eyeball, which is tough and provides structure.
- **Choroid**: This layer is located between the sclera and retina and contains blood vessels that supply nutrients to the eye. It is made of loosely arranged connective tissue.
- **Retina**: This is the innermost layer that contains photoreceptors and is responsible for converting light into neural signals.

3. **Focusing on Dense Connective Tissue**: Dense connective tissue is characterized by a high concentration of collagen fibers, which provide strength and support.

4. **Identifying the Correct Layer**:
- The **sclera** is primarily composed of dense connective tissue, specifically type 1 collagen fibers. This composition gives the sclera its white appearance and helps maintain the shape of the eyeball.

5. **Conclusion**: Therefore, the layer of the eyeball that contains dense connective tissue is the **sclera**.

### Final Answer:
The dense connective tissue is present in the **sclera** layer of the eyeball.
