At what anatomical point is the surface marking of the femoral artery located?

The surface marking of the femoral artery is located at the mid inguinal point, which is an important anatomical landmark. This point is typically defined as being halfway between the pubic symphysis and the anterior superior iliac spine (ASIS). The femoral artery travels down the thigh beneath the inguinal ligament and is most accessible for examination and procedures at this location.

Understanding the significance of the mid inguinal point is particularly important for clinical procedures, such as catheterizations or in cases of vascular or trauma assessments. Knowing where to locate this artery can facilitate emergency interventions, as it is a central structure in the vascular supply of the lower limb.

The other options refer to locations that are not relevant for the surface marking of the femoral artery. The proximal thigh is too vague and does not specify the exact point of reference used to identify the artery's surface marking. The medial malleolus is at the ankle and relates to the tibial region, while the popliteal fossa is located behind the knee, which is further distally and not associated with the identification of the femoral artery's surface projection.
