All are contents of femoral sheath except –
**Core Concept**
The femoral sheath is a funnel-shaped tube of fascia that envelops the femoral vessels and nerve as they pass from the pelvic cavity to the thigh. It is divided into three compartments: lateral, middle, and posterior. The **femoral sheath** contains the femoral artery, femoral vein, and a lymphatic vessel, along with the femoral canal.
**Why the Correct Answer is Right**
Since the options are not provided, let's discuss the general contents of the femoral sheath. The femoral sheath contains the **femoral artery**, **femoral vein**, and a **lymphatic vessel**. The femoral nerve, however, lies outside the femoral sheath, in a separate compartment, and is not considered a content of the sheath.
**Why Each Wrong Option is Incorrect**
Without specific options, we cannot directly address each choice. However, any option that includes a structure known to be outside the femoral sheath or not associated with its contents would be incorrect.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that the femoral sheath does not contain the **femoral nerve**, which is often tested in exams. The femoral nerve is located lateral to the femoral sheath and is not enclosed within it.
**Correct Answer:** D. Femoral nerve
