GnRH from hypothalamus reaches anterior pituitary through :

Options

A. Nuclei
B. Axon
C. Blood vessels
D. Lymph vessels

Answer

To answer the question "GnRH from hypothalamus reaches anterior pituitary through:", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Source of GnRH**:
- Gonadotropin-releasing hormone (GnRH) is produced in the hypothalamus.

2. **Identify the Target**:
- The target of GnRH is the anterior pituitary gland, which is responsible for the secretion of various hormones including luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

3. **Determine the Pathway**:
- GnRH does not travel through nerves to reach the anterior pituitary. Instead, it is released into the bloodstream.

4. **Identify the Transport Mechanism**:
- The hormone travels from the hypothalamus to the anterior pituitary through specialized blood vessels known as the hypothalamic-pituitary portal system. This system consists of a network of blood vessels that directly connects the two regions.

5. **Evaluate the Options**:
- The options provided include:
- Nuclei
- Exome
- Blood vessels
- Lymph vessels
- Among these, the correct answer is **blood vessels**, as they are responsible for transporting GnRH from the hypothalamus to the anterior pituitary.

### Final Answer:
GnRH from the hypothalamus reaches the anterior pituitary through **blood vessels**.
