Which of the following is incorrect about the uterine wall ?

Options

A. Perimetrium - Outer thin covering of peritoneum
B. Myometrium - Middle thick smooth muscle layer
C. Mesometrium - smooth muscle layer below myometrium
D. Endometrium - lnner glandular layer that lines the uterine cavity

Answer

To determine which statement about the uterine wall is incorrect, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding the Uterine Wall Layers**:
- The uterine wall consists of three main layers:
- **Perimetrium**: The outermost layer, which is a thin serous layer.
- **Myometrium**: The middle layer, composed of smooth muscle.
- **Endometrium**: The innermost layer, which is a granular layer lining the uterine cavity.

2. **Analyzing Each Option**:
- **Option 1: Parimaterium** - Matched with "outer thin covering of peritoneum".
- This is **correct**. The perimetrium is indeed the outer serous layer of the uterus.

- **Option 2: Myomatrium** - Matched with "middle thick smooth muscle layer".
- This is also **correct**. The myometrium is the thick muscular layer of the uterus.

- **Option 3: Mesomatrium** - Matched with "smooth muscle layer below the myomatrium".
- This is **incorrect**. The term "mesomatrium" is not typically used to describe a layer of the uterine wall. Instead, it refers to the mesentery associated with the uterus, not a muscle layer.

- **Option 4: Endomaterium** - Matched with "inner granular layer that lines the uterine cavity".
- This is **correct**. The endometrium is indeed the inner layer that lines the uterine cavity.

3. **Conclusion**:
- The incorrect statement is regarding the **mesomatrium**. It is not a smooth muscle layer below the myometrium; rather, it refers to the mesentery of the uterus.

### Final Answer:
The incorrect statement about the uterine wall is related to **mesomatrium**, which is incorrectly matched with "smooth muscle layer below the myomatrium".
