Which of the following is secreted from pars intermedia ?

Options

A. MSH
B. LH
C. FSH
D. TSH

Answer

### Step-by-Step Solution

1. **Understanding the Question**: The question asks which hormone is secreted from the pars intermedia of the pituitary gland.

2. **Identifying the Parts of the Pituitary Gland**: The pituitary gland is divided into two main parts: the anterior pituitary (adenohypophysis) and the posterior pituitary (neurohypophysis). The anterior pituitary is further divided into pars distalis and pars intermedia.

3. **Hormones Secreted by Each Part**:
- **Neurohypophysis (Posterior Pituitary)**: This part releases hormones like Antidiuretic Hormone (ADH) and Oxytocin.
- **Adenohypophysis (Anterior Pituitary)**: This part secretes several hormones including Growth Hormone, Thyroid Stimulating Hormone (TSH), Luteinizing Hormone (LH), and Follicle Stimulating Hormone (FSH).
- **Pars Intermedia**: This section specifically secretes Melanocyte Stimulating Hormone (MSH).

4. **Analyzing the Options**:
- **Option 1: MSH (Melanocyte Stimulating Hormone)** - This is the hormone secreted by the pars intermedia.
- **Option 2: LH (Luteinizing Hormone)** - This is secreted by the pars distalis, not the pars intermedia.
- **Option 3: FSH (Follicle Stimulating Hormone)** - This is also secreted by the pars distalis.
- **Option 4: TSH (Thyroid Stimulating Hormone)** - This is secreted by the pars distalis as well.

5. **Conclusion**: The only hormone secreted by the pars intermedia is MSH. Therefore, the correct answer is MSH.

### Final Answer
**The hormone secreted from the pars intermedia is Melanocyte Stimulating Hormone (MSH).**
