Goblet cells (in GIT) are a type of -

Options

A. Multicellular gland
B. Unicellular gland
C. Intercellular gland
D. Salivary gland

Answer

**Step-by-Step Solution:**

1. **Understanding Goblet Cells**: Goblet cells are specialized cells found in the gastrointestinal tract (GIT). They are primarily responsible for secreting mucus.

2. **Identifying the GIT**: GIT stands for the gastrointestinal tract, which includes the stomach and intestines. It plays a crucial role in digestion and absorption.

3. **Defining Glands**: A gland can be defined as a cell, tissue, or organ that secretes substances such as enzymes, hormones, or mucus. Goblet cells are considered a type of gland because they secrete mucus.

4. **Characteristics of Goblet Cells**: Goblet cells are modified columnar epithelial cells. They have been adapted to perform a glandular function, which means they can secrete mucus effectively.

5. **Secretion of Mucus**: The mucus secreted by goblet cells is sticky and gel-like, primarily composed of mucin. This mucus serves to lubricate and protect the lining of the gastrointestinal tract.

6. **Classification of Goblet Cells**: Goblet cells are unicellular glands, meaning they consist of a single cell rather than multiple cells. This distinguishes them from multicellular glands.

7. **Conclusion**: Based on the characteristics and functions described, goblet cells in the GIT are classified as unicellular mucous-secreting glands.

**Final Answer**: Goblet cells in the GIT are a type of unicellular gland.
