2. **Identifying the Location:**
- The eye has two main cavities: the anterior chamber (filled with aqueous humour) and the vitreous cavity (filled with vitreous humour). The vitreous cavity is situated between the lens and the retina.

3. **Characteristics of Vitreous Humour:**
- Vitreous humour is classified as a type of connective tissue, specifically mucoid connective tissue. This type of tissue is embryonic in origin and is not replaceable once formed.

4. **Function of Vitreous Humour:**
- The primary function of vitreous humour is to maintain intraocular pressure within the eye, which is crucial for the eye's shape and overall function.

5. **Identifying the Correct Answer:**
- Given the options provided, the correct classification of vitreous humour is "mucoid connective tissue." Other options like reticular, areolar, and adipose tissues do not accurately describe vitreous humour.

6. **Conclusion:**
- Therefore, the vitreous humour is best defined as a type of mucoid connective tissue that is non-replaceable and plays a vital role in maintaining the eye's internal pressure.

**Final Answer:**
- Vitreous humour is a type of mucoid connective tissue.
