Nature of ceruminous glands is :

Options

A. Merocrine
B. Holocrine
C. Modified Apocrine
D. Both (2) and (3)

Answer

### Step-by-Step Solution:

1. **Understanding Ceruminous Glands**:
- Ceruminous glands are specialized glands located in the external auditory canal. They are responsible for producing earwax (cerumen), which helps protect the ear canal.

2. **Identifying the Type of Gland**:
- Ceruminous glands are classified as modified apocrine glands. This means they have characteristics of apocrine glands, which secrete substances by accumulating them in secretory granules and then releasing them through the breakdown of these granules.

3. **Comparison with Other Gland Types**:
- **Merocrine Glands**: These glands secrete their products via exocytosis without losing any cellular material. An example is the salivary glands.
- **Holocrine Glands**: In these glands, the entire cell disintegrates to release its secretion. An example is the sebaceous glands (oil glands).
- **Apocrine Glands**: These glands accumulate their secretion at the apical surface, which then pinches off to release the secretion. Ceruminous glands fall under this category but are specifically termed modified apocrine glands.

4. **Conclusion**:
- Based on the characteristics and classification, ceruminous glands are best described as modified apocrine glands.

### Final Answer:
The nature of ceruminous glands is **Modified Apocrine**.
