- Perforating veinsVenae perforantesShort valved veins that pierce the deep fascia of the lower limb to carry blood from the superficial veins into the deep veins.
- Pericallosal arteryArteria pericallosaThe continuation of the anterior cerebral artery that runs backwards over the corpus callosum on the medial surface of the hemisphere.
- Phalanges of the footOssa digitorum pedisThe phalanges of the foot are the short bones of the toes: two in the great toe and three in each of the four lesser toes.
- Phalanges of the handOssa digitorum manusThe phalanges of the hand are the small long bones of the fingers and thumb: two in the thumb and three in each finger.
- Pineal glandGlandula pinealisA small, pine-cone-shaped endocrine gland on the roof of the third ventricle, part of the epithalamus, that secretes melatonin in darkness.
- Piriformis muscleMusculus piriformisA pear-shaped muscle passing from the front of the sacrum through the greater sciatic foramen to the top of the greater trochanter.
- Pisohamate ligamentLigamentum pisohamatumA strong band at the base of the palm linking the pisiform with the hamate's hook and flooring the ulnar canal.
- Pisometacarpal ligamentLigamentum pisometacarpeumA short palmar band at the ulnar edge of the wrist, linking the pisiform with the base of the little-finger metacarpal.
- Pisotriquetral ligamentLigamentum pisotriquetrumThe capsular ligament of the small joint between the pisiform and the palmar surface of the triquetrum, on the ulnar side of the wrist.
- Plantar archArcus plantarisThe deep arterial arch of the sole, where the lateral plantar artery meets the deep plantar artery coming down from the dorsum.
- Plantar calcaneocuboid ligamentLigamentum calcaneocuboideum plantareThe short plantar ligament: a wide, very strong sole band joining the front of the calcaneus to the cuboid, under the long plantar ligament.
- Plantar calcaneonavicular ligamentLigamentum calcaneonaviculare plantareThe spring ligament: a thick sling under the head of the talus, running from the heel bone's sustentaculum tali to the navicular.
- Plantar cuboideonavicular ligamentLigamentum cuboideonaviculare plantareA small fibrous band in the sole of the midfoot that ties the underside of the navicular to the underside of the cuboid.
- Plantar cuneocuboid ligamentLigamentum cuneocuboideum plantareA short fibrous band in the sole that joins the cuboid to the lateral cuneiform at the cuneocuboid joint of the midfoot.
- Plantar cuneonavicular ligamentsLigamenta cuneonavicularia plantariaFibrous bands in the sole that fasten the underside of the navicular to the three cuneiform bones in front of it.
- Plantar digital veinsVenae digitales plantaresSmall veins on the undersides of the toes that drain the plantar skin of the digits and unite to form the plantar metatarsal veins.
- Plantar intercuneiform ligamentsLigamenta intercuneiformia plantariaShort bands on the sole of the midfoot that tie each cuneiform bone to its neighbour on the underside.
- Plantar interossei musclesMusculi interossei plantaresThree small muscles deep in the sole, each lying under a lateral metatarsal and drawing its toe towards the second toe.
- Plantar interphalangeal ligamentsLigamenta interphalangea plantariaThick fibrocartilaginous plates forming the floor of each interphalangeal joint of the toes and stopping the joints bending backwards.
- Plantar metatarsal arteriesArteriae metatarseae plantaresFour arteries arising from the plantar arch that run forwards between the metatarsal bones and divide into plantar digital arteries.
- Plantar metatarsal ligamentsLigamenta metatarsea plantariaShort transverse bands in the sole that bind the bases of neighbouring metatarsal bones together at the intermetatarsal joints.
- Plantar metatarsal veinsVenae metatarseae plantaresDeep veins running back in the spaces between the metatarsal bones on the sole, draining the toes into the deep plantar venous arch.
- Plantar metatarsophalangeal ligamentsLigamenta metatarsophalangea plantariaThe plantar plates of the metatarsophalangeal joints: fibrocartilage pads under each metatarsal head that bear weight and stop the toes over-extending.
- Plantar tarsometatarsal ligamentsLigamenta tarsometatarsea plantariaLongitudinal and oblique bands on the underside of the midfoot binding the cuneiforms and cuboid to the bases of the metatarsals.
