When the discharge from a secretary cell involves no cytoplasmic damage to the cell itself, such a glandular cell is known as  

Options

A. acrine
B. apocrine
C. merocrine
D. Holocrine

Answer

To solve the question about the type of glandular cell that discharges its secretions without causing cytoplasmic damage, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Types of Glands**:
- There are different types of glandular cells based on how they release their secretions: holocrine, apocrine, and merocrine.

2. **Analyzing Holocrine Glands**:
- Holocrine glands release their secretions by rupturing the entire cell. This means that the cell is destroyed in the process, leading to cytoplasmic damage. Therefore, holocrine is not the correct answer.

3. **Analyzing Apocrine Glands**:
- Apocrine glands release their secretions by losing a small portion of their glandular cell body. This process also causes some damage to the cell, although it is less severe than holocrine. Hence, apocrine is also not the correct answer.

4. **Analyzing Merocrine Glands**:
- Merocrine glands release their secretions via exocytosis, which means that the secretory products are expelled without any damage to the cell itself. The cell remains intact and can continue to produce more secretions. This characteristic fits the requirement of the question.

5. **Conclusion**:
- Based on the analysis, the correct answer is **merocrine** glands, as they discharge their secretions without causing cytoplasmic damage to the cell.

### Final Answer:
The glandular cell that discharges its secretions without causing cytoplasmic damage is known as **merocrine**.
