Which of the following is the least vascular pa of uterus :
💡 Explanation
## **Core Concept**
The uterus receives its blood supply primarily from the **uterine arteries**, which are branches of the **internal iliac arteries**. The vascularity of different parts of the uterus varies, with some areas being more vascular than others.
## **Why the Correct Answer is Right**
The **lower uterine segment** or **isthmus** is the area between the body of the uterus and the cervix. This region is known for having relatively poor vascularity compared to the rest of the uterus, which is richly supplied with blood. The fundus and body of the uterus have a rich network of vessels, making them more vascular.
## **Why Each Wrong Option is Incorrect**
- **Option A:** The fundus of the uterus is one of the most vascular parts, receiving a significant supply from the **arcuate arteries** that run along the uterine fundus.
- **Option B:** The body of the uterus, similar to the fundus, is well-vascularized, making it not the least vascular part.
- **Option D:** The cervix, while less vascular than the uterine body or fundus, still has a notable blood supply, particularly from **cervical branches** of the uterine artery.
## **Clinical Pearl / High-Yield Fact**
A key clinical consideration during **cesarean sections** or **hysterectomies** is the vascularity of the uterus. The lower uterine segment, being less vascular, is often the site for making the uterine incision during a cesarean section to minimize bleeding.
