Select the set of mesodermal structures from the following.

Options

A. Enamel, Pancreas
B. Testis, Kidneys
C. Liver, Hypothalamus
D. Pituitary, Dentine

Answer

To solve the question of selecting the set of mesodermal structures, we need to identify which of the given options are derived from the mesoderm germ layer. The three primary germ layers are ectoderm, mesoderm, and endoderm, each giving rise to different tissues and organs.

### Step-by-Step Solution:

1. **Understand the Germ Layers**:
- Ectoderm: Gives rise to structures such as skin, hair, nails, and the nervous system.
- Mesoderm: Forms muscles, bones, the circulatory system, and certain organs.
- Endoderm: Develops into the gastrointestinal tract, liver, pancreas, and respiratory system.

2. **Analyze Each Option**:
- **Enamel**: Derived from ectoderm. (Not mesodermal)
- **Pancreas**: Derived from endoderm. (Not mesodermal)
- **Testes**: Derived from mesoderm. (Mesodermal)
- **Kidneys**: Derived from mesoderm. (Mesodermal)
- **Liver**: Derived from endoderm. (Not mesodermal)
- **Hypothalamus**: Derived from ectoderm. (Not mesodermal)
- **Pituitary**: Derived from ectoderm. (Not mesodermal)
- **Dentine**: Derived from ectoderm. (Not mesodermal)

3. **Identify Mesodermal Structures**:
- From the analysis, the only structures that are derived from the mesoderm are the **testes** and **kidneys**.

4. **Final Answer**:
- The correct set of mesodermal structures from the options provided is **testes and kidneys**.
