Glandular epithelia contain cells that produce :

Options

A. excorine secretions only
B. exocrine or endocrine secretions
C. endocrine secretions only
D. secretions released from goblet cells only

Answer

**Step-by-Step Solution:**

1. **Understanding Glandular Epithelia**: Glandular epithelia are specialized types of epithelial tissue that are primarily responsible for the production and secretion of various substances in the body.

2. **Types of Secretions**: Glandular epithelia can produce different types of secretions. These include:
- **Exocrine Secretions**: These are secretions that are released through ducts to the surface of organs or into body cavities. Examples include sweat, saliva, and digestive enzymes.
- **Endocrine Secretions**: These are secretions that are released directly into the bloodstream without the use of ducts. Examples include hormones produced by glands like the thyroid and adrenal glands.

3. **Identifying the Correct Answer**: The question asks what glandular epithelia contain cells that produce. Since glandular epithelia can produce both exocrine and endocrine secretions, the correct answer must encompass both types.

4. **Evaluating the Options**:
- **Exocrine secretions only**: This option is incorrect as it does not include endocrine secretions.
- **Exocrine or endocrine secretions**: This option is correct as it includes both types of secretions produced by glandular epithelia.
- **Endocrine secretions only**: This option is incorrect as it does not include exocrine secretions.
- **Secretions released from goblet cells only**: This option is incorrect as goblet cells are specific to mucous secretion and do not represent the full range of glandular epithelia.

5. **Conclusion**: The glandular epithelia contain cells that produce both exocrine and endocrine secretions. Therefore, the correct answer is **exocrine or endocrine secretions**.
