Gonadotropin releasing hormone secreted by hypothalamus hormone acts on ---------- and stimulates the production of -------------------

Options

A. anterior pituitary gland ; LH and oxytocin
B. anterior pituitary gland; LH and FSH
C. posterior pituitary gland ; oxytocin and FSH
D. posterior pituitary gland ; LH and relaxin

Explanation

To answer the question regarding the gonadotropin-releasing hormone (GnRH) secreted by the hypothalamus, we can break down the solution into the following steps:

### Step-by-Step Solution:

1. **Identify the Source of GnRH**:
- Gonadotropin-releasing hormone (GnRH) is secreted by the hypothalamus.

2. **Determine the Target Organ**:
- GnRH acts on the anterior pituitary gland. It is important to note that the pituitary gland has two main parts: the anterior and the posterior. GnRH specifically targets the anterior pituitary.

3. **Identify the Hormones Stimulated by GnRH**:
- Upon stimulation by GnRH, the anterior pituitary gland releases two key hormones: Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH).

4. **Summarize the Functions of FSH and LH**:
- FSH is involved in the development of ovarian follicles in females and stimulates Sertoli cells in males for spermatogenesis.
- LH triggers ovulation in females and stimulates Leydig cells in males to produce testosterone.

5. **Final Answer**:
- Therefore, the gonadotropin-releasing hormone secreted by the hypothalamus acts on the anterior pituitary and stimulates the production of FSH and LH.

### Final Answer:
Gonadotropin-releasing hormone secreted by the hypothalamus acts on the **anterior pituitary** and stimulates the production of **FSH and LH**.
