| popliteal communicating nerve | <anatomy, nerve> Arises from the tibial in the popliteal space, passes down the calf between the two heads of the gastrocnemius and unites in the middle of the leg with the communicating branch of the common peroneal to form the sural nerve, distributed to the skin of the distal and lateral surfaces of the leg and ankle. Synonym: nervus cutaneus surae medialis, medial cutaneous nerve of leg, popliteal communicating nerve, tibial communicating nerve. (05 Mar 2000) |

| popliteal cyst | A synovial cyst in the popliteal space arising from the semimembranous bursa or the knee joint. (12 Dec 1998) |
| popliteal entrapment syndrome | <syndrome> A crush syndrome resulting from compression of the popliteal artery and impairment of its blood flow by structures of the popliteal space. (05 Mar 2000) |
| popliteal fascia | The fascia that covers the popliteal fossa, continuous with fascia lata superiorly and crural fascia inferiorly. (05 Mar 2000) |
| popliteal fossa | The diamond-shaped space posterior to the knee joint bounded superficially by the diverging biceps femoris and semimembranosus muscles above and inferiorly by the two heads of the gastrocnemius muscle; deeply, the fossa is bound superiorly by the diverging supracondylar lines of the femur and the soleal line of the tibia inferiorly. Contents: tibial nerve, popliteal artery, vein, fat. Synonym: fossa poplitea, poples, ham, popliteal region, popliteal space, popliteus. (05 Mar 2000) |
| popliteal fossa: the | Hollow behind the knee. (12 Dec 1998) |
| popliteal groove | A groove on the lateral condyle of the femur between the epicondyle and the articular margin. Its anterior end gives origin to the popliteus muscle; its posterior end lodges the tendon of the muscle when the knee is fully flexed. Synonym: sulcus popliteus. (05 Mar 2000) |
| popliteal line | A ridge which extends obliquely downward and medially across the back of the tibia from the fibular articular facet; it gives origin to the soleus muscle. Synonym: linea musculi solei, line for soleus muscle, linea poplitea, popliteal line. (05 Mar 2000) |
| popliteal lymph nodes | Two groups of nodes located in the popliteal fossa: the superficial popliteal lymph nodes, located around the termination of the small saphenous vein, that drain the skin of the back of the leg and lateral side of the foot; and the deep popliteal lymph nodes, located around the popliteal vessels, that drain the superficial group, the deep structures of the leg, and the knee joint. Synonym: nodi lymphatici popliteales. (05 Mar 2000) |
| popliteal muscle | <anatomy, muscle> Origin, lateral condyle of femur; insertion, posterior surface of tibia above oblique line; action, from the fully extended and "locked" position, rotates the femur medially, on the fixed (planted) tibial plateau about 5 |
| popliteal notch | The deep fossa between the femoral condyles in which the cruciate ligaments are attached. Synonym: fossa intercondylaris, intercondyloid fossa, intercondylic fossa, intercondyloid notch, popliteal notch. (05 Mar 2000) |
| popliteal plane of femur | The posterior surface of the lower end of the femur between the diverging lips of the linea aspera. Synonym: facies poplitea femoris, planum popliteum, popliteal plane of femur. (05 Mar 2000) |
| popliteal plexus | Plexus popliteus, a nerve plexus surrounding the popliteal artery, derived from the femoral plexus. (05 Mar 2000) |
| popliteal pterygium syndrome | <syndrome> An inherited condition with a web behind the knee. (a pterygium is a winglike triangular membrane.) (12 Dec 1998) |
| popliteal region | The diamond-shaped space posterior to the knee joint bounded superficially by the diverging biceps femoris and semimembranosus muscles above and inferiorly by the two heads of the gastrocnemius muscle; deeply, the fossa is bound superiorly by the diverging supracondylar lines of the femur and the soleal line of the tibia inferiorly. Contents: tibial nerve, popliteal artery, vein, fat. Synonym: fossa poplitea, poples, ham, popliteal region, popliteal space, popliteus. (05 Mar 2000) |
