  • Popliteal line of tibia

    A line on the posterior surface of the tibia, extending obliquely downward from the fibular facet on the lateral condyle to the medial border of the bone.  

  • Popliteal line of femur

    An oblique line on the posterior surface of the femur.  

  • Pectineal line

    The line on the posterior surface of the femur extending downward from the lesser trochanter. It is the portion of the iliopectineal line formed by the os pubis.  

  • Parasternal line

    The line midway between the nipple and the border of the sternum.  

  • Pulmonary ligament

    A fold of pleura that extends from the hilus of the lung to the base of the medial surface of the lung.  

  • Pubic arcuate ligament

    The ligaments connecting the pubic bones at the symphysis pubis, including anterior and superior pubic ligaments and the arcuate (inferior) ligament.  

  • Pterygomandibular ligament

    The ligament between the apex of the internal pterygoid plate of the sphenoid bone and the posterior extremity of the internal oblique line of the mandible.  

  • Posterior tibiotalar ligament

    Ligament of the ankle that connects the posteromedial portion of the talus to the posterior portion of the medial malleolus, preventing posterior displacement of the talus within the mortise, especially when the ankle is dorsiflexed. The posterior tibiotalar ligament is categorized as part of the deltoid ligament complex of the ankle.  

  • Posterior tibiofibular ligament

    A broad ligament that binds the fibula to the tibia; located on the posterior half of the distal fibula, superior to the lateral malleolus. The posterior tibiofibular ligament is part of the distal ankle syndesmosis.  

  • Posterior talofibular ligament

    A ligament of the lateral ankle that attaches the posterior portion of the talus, and a portion of the posterolateral calcaneus, to the medial malleolus. The posterior talofibular ligament limits the excessive dorsiflexion and inversion of the talus within the ankle mortise.
