Conjunctiva of eye is derived from

Options

A. Mesoderm
B. Ectoderm
C. Endoderm
D. Endomesoderm.

Answer

**Step-by-Step Solution:**

1. **Understanding Conjunctiva**: The conjunctiva is a thin, transparent membrane that lines the inner surface of the eyelids and covers the white part of the eyeball. It plays a crucial role in protecting the eye and keeping it moist.

2. **Embryonic Development**: During embryonic development, three primary germ layers are formed: ectoderm, mesoderm, and endoderm. Each of these layers gives rise to different tissues and organs in the body.

3. **Identifying Germ Layers**:
- **Ectoderm**: The outermost layer, which gives rise to structures such as the skin, hair, nails, and the nervous system.
- **Mesoderm**: The middle layer, which forms muscles, bones, and the circulatory system.
- **Endoderm**: The innermost layer, which develops into internal organs such as the gut and lungs.

4. **Determining the Origin of Conjunctiva**: The conjunctiva is derived from the ectoderm. This means that during embryonic development, the cells that will form the conjunctiva originate from the ectoderm layer.

5. **Conclusion**: Therefore, the conjunctiva of the eye is derived from the ectoderm, which is the outer germ layer of the embryo.

**Final Answer**: The conjunctiva of the eye is derived from the ectoderm.
