The tissues that are derived from mesoderm are:  

Options

A. neural
B. muscular
C. connective
D. both 2 & 3

Answer

To answer the question regarding the tissues derived from the mesoderm, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Germ Layers**:
- During embryonic development, the zygote undergoes several divisions to form a structure called the blastula, which eventually leads to the formation of three primary germ layers: ectoderm, mesoderm, and endoderm.

2. **Identifying the Mesoderm**:
- The mesoderm is one of these three germ layers. It plays a crucial role in the development of various tissues and organs in the body.

3. **Tissues Derived from Mesoderm**:
- The mesoderm primarily gives rise to:
- **Muscle Tissue**: This includes skeletal, cardiac, and smooth muscle tissues.
- **Connective Tissue**: This encompasses a diverse group of tissues, including bone, blood, cartilage, and adipose tissue.

4. **Exclusion of Other Tissues**:
- The neural tissue (nervous tissue) is derived from the ectoderm, not the mesoderm. Therefore, it is not included in the tissues derived from the mesoderm.

5. **Conclusion**:
- Based on the above information, the correct answer to the question is that the tissues derived from mesoderm are muscular and connective tissues, which corresponds to option "both 2 and 3".

### Final Answer:
The tissues that are derived from mesoderm are muscular and connective tissues (both 2 and 3).
