Nerves · Lower limbObturator nerveNervus obturatoriusA lumbar plexus nerve that runs along the side wall of the pelvis and through the obturator canal to the adductor muscles of the thigh.
Skeleton · Lower limbPatellaThe patella, or kneecap, is a flat triangular bone set in the quadriceps tendon at the front of the knee joint.
Arteries · Lower limbPatellar anastomosisRete patellareA network of small linked arteries around the patella and the adjoining ends of the thigh and leg bones, fed by the genicular arteries.
Muscles · Lower limbPectineus muscleMusculus pectineusA flat, four-sided muscle at the top of the inner thigh, running from the pecten pubis to just below the lesser trochanter.
Arteries · Lower limbPerforating femoral arteriesArteriae perforantes femorisA series of branches of the deep femoral artery that pierce the adductor muscles to reach and supply the back of the thigh.
Veins · Lower limbPerforating veinsVenae perforantesShort valved veins that pierce the deep fascia of the lower limb to carry blood from the superficial veins into the deep veins.
Muscles · Lower limbPiriformis muscleMusculus piriformisA pear-shaped muscle passing from the front of the sacrum through the greater sciatic foramen to the top of the greater trochanter.
Muscles · Lower limbPlantar interossei musclesMusculi interossei plantaresThree small muscles deep in the sole, each lying under a lateral metatarsal and drawing its toe towards the second toe.
Muscles · Lower limbPlantaris muscleMusculus plantarisA small calf muscle behind the knee whose very long, thin tendon runs down between gastrocnemius and soleus to the heel.
Arteries · Lower limbPopliteal arteryArteria popliteaThe femoral artery's continuation behind the knee, running through the popliteal fossa to divide below popliteus.
Veins · Lower limbPopliteal veinVena popliteaThe deep vein behind the knee, formed by the tibial veins and continuing upwards as the femoral vein.
Joints and ligaments · Lower limbPopliteofibular ligamentLigamentum popliteofibulareA short, strong band at the back and outer side of the knee joining the popliteus tendon to the fibular head.
Muscles · Lower limbPopliteus muscleMusculus popliteusA thin, triangular muscle in the floor of the popliteal fossa that unlocks the fully straightened knee.
Nerves · Lower limbPosterior branch of obturator nerveRamus posterior nervi obturatoriiThe deep division of the obturator nerve, passing through obturator externus to supply the deep adductors and send a twig to the knee.
Joints and ligaments · Lower limbPosterior cruciate ligamentLigamentum decussatum posteriusThe stronger of the two cruciate ligaments, running from the back of the tibia up and forwards to the medial femoral condyle.
Nerves · Lower limbPosterior femoral cutaneous nerveNervus cutaneus femoris posteriorA sensory branch of the sacral plexus that supplies the skin of the lower buttock, the back of the thigh and the upper calf.
Joints and ligaments · Lower limbPosterior ligament of fibular headLigamentum posterius capitis fibulaeA single thick band strengthening the back of the upper tibiofibular joint, deep to the popliteus tendon.
Joints and ligaments · Lower limbPosterior meniscotibial ligament (Lateral meniscus)Ligamentum meniscotibiale posterius (Meniscus lateralis)The fibrous root that anchors the back end of the lateral meniscus to the posterior intercondylar area of the tibia.
Joints and ligaments · Lower limbPosterior meniscotibial ligament (Medial meniscus)Ligamentum meniscotibiale posterius (Meniscus medialis)The fibrous root that anchors the back end of the medial meniscus to the posterior intercondylar area of the tibia.
Nerves · Lower limbPosterior root of posterior femoral cutaneous nerveRadix posterior nervi cutanei femoris posteriorisThe contribution to the posterior femoral cutaneous nerve that comes from the posterior divisions of the first and second sacral nerves.
Nerves · Lower limbProper plantar digital branches of lateral plantar nerveRami digitales plantares proprii nervi plantaris lateralisThe terminal toe nerves of the lateral plantar nerve, serving the plantar skin of the little toe's outer edge and the fourth web space.
Nerves · Lower limbProper plantar digital branches of medial plantar nerveRami digitales plantares proprii nervi plantaris medialisThe terminal toe nerves of the medial plantar nerve, supplying the plantar skin of the medial three and a half toes and their nail beds.
Muscles · Lower limbPsoas majorA long, thick muscle beside the lumbar spine that runs down over the pelvic brim to the lesser trochanter, joining iliacus.
Joints and ligaments · Lower limbPubofemoral ligamentLigamentum pubofemoraleA band on the lower front of the hip capsule, running from the pubis to the capsule and the iliofemoral ligament.
