The correct Answer is:
To answer the question, "Which layer of the uterus exhibits strong contraction during parturition?", we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Term 'Parturition':** - Parturition refers to the process of giving birth or the act of delivering a fetus. 2. **Identify the Layers of the Uterus:** - The uterus consists of three layers: - **Perimetrium**: The outermost layer, which is thin and protective. - **Myometrium**: The middle layer, which is thick and muscular. - **Endometrium**: The innermost layer, which is involved in the menstrual cycle and sheds monthly. 3. **Analyze the Function of Each Layer During Parturition:** - The **Endometrium** is not responsible for contractions; it sheds during menstruation. - The **Perimetrium** is primarily protective and does not contribute to contractions. - The **Myometrium**, being the muscular layer, is responsible for the strong contractions necessary for childbirth. 4. **Conclude with the Correct Answer:** - The layer of the uterus that exhibits strong contraction during parturition is the **Myometrium**. ### Final Answer: - The correct answer is **Myometrium** (Option B). ---
