Embryonic connective tissue is formed from
(a) Ectoderm
(b) Endoderm
(c) Mesenchyma
(d) Mesoglea

Options

A. Ectoderm
B. Endoderm
C. Mesenchyma
D. Mesogloes.

Answer

To solve the question regarding the formation of embryonic connective tissue, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Germ Layers**:
- The three primary germ layers in embryonic development are ectoderm, mesoderm, and endoderm. Each layer gives rise to different types of tissues and organs in the body.

2. **Identify the Role of Each Germ Layer**:
- **Ectoderm**: This layer primarily develops into the nervous system and skin. It does not contribute to connective tissues.
- **Endoderm**: This layer forms the inner linings of the digestive tract and respiratory system, as well as certain organs. It is not involved in the formation of connective tissues.
- **Mesoderm**: This layer is responsible for forming muscles, bones, and connective tissues. It includes mesenchyme, which is a type of embryonic connective tissue.
- **Mesoglea**: This is a gelatinous substance found in some invertebrates, such as jellyfish, and is not related to human embryonic development.

3. **Focus on Mesenchyme**:
- Mesenchyme is a type of connective tissue that is derived from the mesoderm. It plays a crucial role in the development of various connective tissues in the body.

4. **Eliminate Incorrect Options**:
- Since ectoderm, endoderm, and mesoglea do not contribute to the formation of connective tissues, we can eliminate options (a), (b), and (d).

5. **Select the Correct Answer**:
- The only option left that is associated with the formation of embryonic connective tissue is (c) Mesenchyma.

### Final Answer:
The correct answer is (c) Mesenchyma.
