Which statement correctly defines the femoral neck?

• A. The projection on the medial/superior portion of the femur
• B. The distance between the femoral axis and the center of the head
• C. The narrow area just below the head of the femur
• D. The main extensor of the hip

Answer: (C)

The main idea is identifying the narrow region that connects the femoral head to the shaft. The femoral neck is the slender portion that sits just below the head, linking it to the shaft of the bone. That description—“the narrow area just below the head of the femur”—matches this region precisely. The other statements don’t describe this part: one refers to a projection on the medial/superior aspect, which isn’t how the neck is defined; another talks about the distance between the femoral axis and the head’s center (that’s a measurement like offset, not the neck itself); and the last mentions a muscle that extends the hip, which is unrelated to the bone’s anatomy.
