Chromatophores in skin of frog found in stratum

Options

A. Comeum
B. Compactum
C. Germinativum
D. Mostly spongiosum

Answer

**Step-by-Step Solution:**

1. **Understanding Chromatophores**: Chromatophores are specialized pigment-containing cells found in the skin of various animals, including frogs. They are responsible for producing colors and can change the color of the skin.

2. **Skin Structure of Frogs**: The skin of frogs is composed of two main layers: the outer epidermis and the inner dermis. These layers are separated by a basement membrane.

3. **Layers of the Epidermis**: The epidermis has several layers:
- The outermost layer is known as the **stratum corneum**, which is thin, scaly, and cornified.
- The innermost layer is called the **stratum germinatum** (or germinativum), also known as the Malpighian layer.
- Between these two layers, there exists a transitional layer.

4. **Layers of the Dermis**: The dermis is thicker than the epidermis and is also divided into two layers:
- The outer layer is called the **stratum spongiosum**.
- The innermost layer is referred to as the **stratum compactum**.

5. **Location of Chromatophores**: The chromatophores in the skin of frogs are specifically located in the **superficial part of the stratum spongiosum** layer of the dermis.

6. **Final Answer**: Therefore, the chromatophores in the skin of a frog are found in the **stratum spongiosum**.
