Options

A. mesometrium
B. epimetrium
C. myometrium
D. endometrium

Answer

To solve the question about which layer of the uterus exhibits strong contractions during the delivery of a baby, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Layers of the Uterus**:
The uterus has three main layers:
- **Perimetrium**: The outermost layer.
- **Myometrium**: The middle layer.
- **Endometrium**: The innermost layer where the blastocyst attaches.

2. **Understand the Function of Each Layer**:
- The **perimetrium** serves as a protective outer covering.
- The **endometrium** is involved in the implantation of the embryo and the menstrual cycle.
- The **myometrium** is responsible for the contractions of the uterus.

3. **Focus on the Process of Childbirth**:
During childbirth (parturition), the uterus needs to contract to help deliver the baby. These contractions are crucial for pushing the baby out.

4. **Identify the Role of Hormones**:
The hormone **oxytocin**, released by the maternal pituitary gland, stimulates the myometrium to contract vigorously during labor.

5. **Conclude the Answer**:
Given that the myometrium is the layer responsible for the strong contractions during delivery, the correct answer is **myometrium**.

### Final Answer:
The layer of the uterus that exhibits strong contractions during the delivery of the baby is the **myometrium**.
