pit, known in medicine as the popliteal fossa, is the hollow region located just behind the bone forming the knee joint
. It is an area of passage for several vascular and nervous structures, notably the popliteal artery
, which carries oxygenated blood
to areas below the knee, the small saphenous vein
that joins the popliteal vein
in the knee pit, and also the sciatic nerve
, which divides into two branches here. The popliteal fossa may be susceptible to various anomalies, of which the most frequent is the popliteal cyst
, a small, but often painful, mass.
