Growth hormone is secreted by

Options

A. Acidophilic `alpha`-cells
B. Acidophilic `beta`-cells
C. Basophilic `alpha`-cells
D. Basophilic `beta`-cells.

Answer

**Step-by-Step Solution:**

1. **Identify the Source of Growth Hormone**: Growth hormone (GH) is primarily secreted by the pituitary gland, specifically from its anterior lobe.

2. **Understand the Types of Cells in the Anterior Pituitary**: The anterior lobe of the pituitary gland contains different types of cells, including acidophilic and basophilic cells.

3. **Focus on Acidophilic Cells**: Among these cells, the acidophilic cells are responsible for secreting growth hormone. These cells are known as somatotrophs.

4. **Define Somatotrophs**: Somatotrophs are specialized cells in the anterior pituitary that produce and release somatotropin, which is another name for growth hormone.

5. **Conclude the Answer**: Therefore, the growth hormone is secreted by acidophilic alpha cells in the anterior lobe of the pituitary gland.

**Final Answer**: Growth hormone is secreted by acidophilic alpha cells.
