Estrogen, progesterone, prolactin and oxytocin in joint effort cause milk production and ejection. This is `"…............"` effect of hormones

Options

A. Antagonistic
B. Synergistic
C. Amplification
D. Inhibition

Answer

To solve the question regarding the effect of hormones involved in milk production and ejection, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Hormones Involved**: The hormones mentioned in the question are Estrogen, Progesterone, Prolactin, and Oxytocin.

2. **Understand the Function of Each Hormone**:
- **Estrogen**: Plays a role in the development of mammary glands.
- **Progesterone**: Prepares the mammary glands for milk production.
- **Prolactin**: Stimulates milk production in the mammary glands.
- **Oxytocin**: Triggers the ejection of milk from the mammary glands.

3. **Analyze the Interaction of These Hormones**: The question states that these hormones work together to achieve the function of milk production and ejection.

4. **Define the Types of Hormonal Effects**:
- **Antagonistic Effect**: When hormones have opposite effects.
- **Synergistic Effect**: When two or more hormones work together to produce a combined effect.
- **Amplification**: Refers to increasing the effect of a hormone.
- **Inhibition**: Refers to stopping or reducing hormone production.

5. **Determine the Correct Type of Effect**: Since all four hormones are working together to achieve the single function of milk production and ejection, this indicates a synergistic effect.

6. **Select the Correct Answer**: The correct answer to the question is "synergistic," which corresponds to option 2.

### Final Answer:
The effect of hormones involved in milk production and ejection is the **synergistic effect** of hormones.
