MSH is secreted by which part of pituitary

Options

A. Pars distalis
B. Pars tuberalis
C. Pars intermedia
D. Pars nervosa

Answer

To answer the question "MSH is secreted by which part of the pituitary?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Hormone**: MSH stands for Melanocyte Stimulating Hormone. It is important to know what this hormone does. MSH primarily stimulates melanocytes, which are cells responsible for the pigmentation of the skin.

2. **Identify the Pituitary Gland Structure**: The pituitary gland is divided into two main parts: the anterior pituitary (adenohypophysis) and the posterior pituitary (neurohypophysis).

3. **Explore the Anterior Pituitary**: The anterior pituitary consists of two regions: Pars Distalis and Pars Intermedia. The Pars Distalis is responsible for secreting several hormones such as LH (Luteinizing Hormone), FSH (Follicle Stimulating Hormone), and TSH (Thyroid Stimulating Hormone).

4. **Focus on Pars Intermedia**: The Pars Intermedia is a smaller region of the anterior pituitary and is known to secrete only one hormone, which is the Melanocyte Stimulating Hormone (MSH).

5. **Conclusion**: Based on the information, we can conclude that MSH is secreted by the Pars Intermedia of the pituitary gland.

### Final Answer:
MSH is secreted by the Pars Intermedia of the pituitary gland.
