| plantar arterial arch | The arterial arch formed by the lateral plantar artery running across the bases of the metatarsal bones and anastomosing with the dorsal pedis artery, either of two bony arch's of the foot, longitudinal arch or transverse arch. See: medial longitudinal arch of foot, lateral longitudinal arch of foot, transverse arch of foot. Synonym: arcus plantaris, plantar arterial arch. (05 Mar 2000) |

| plantar calcaneocuboid ligament | <anatomy> A strong band that passes forward and medially from the plantar surface of the calcaneus to the cuboid bone, actually forming a part of the articular "socket." Synonym: ligamentum calcaneocuboideum plantare. (05 Mar 2000) |
| plantar calcaneonavicular ligament | <anatomy> A dense fibroelastic ligament that extends from the sustentaculum tali to the plantar surface of the navicular bone; it supports the head of the talus. Synonym: ligamentum calcaneonaviculare plantare, inferior calcaneonavicular ligament, spring ligament. (05 Mar 2000) |
| plantar cuboideonavicular ligament | <anatomy> The ligament that unites the plantar surfaces of the cuboid and navicular bones of the tarsus. Synonym: ligamentum cuboideonaviculare plantare. (05 Mar 2000) |
| plantar cuneocuboid ligament | <anatomy> The fibrous band that unites the apex of the lateral cuneiform with the medial margin of the plantar suface of the cuboid. Synonym: ligamentum cuneocuboideum plantare. (05 Mar 2000) |
| plantar cushion | A dense mass of fibrofatty tissue overlying the frog in the foot of the horse; serves an important shock-absorbing function. (05 Mar 2000) |
| plantar digital veins | Drain the plantar and distal dorsal aspects (nail beds) of the toes and pass back to form four metatarsal veins that in turn empty into the plantar venous arch. Synonym: venae digitales plantares. (05 Mar 2000) |
| plantar fascia | The very thick, central portion of the fascia investing the plantar muscles; it radiates toward the toes from the medial process of the calcaneal tuberosity and gives attachment to the short flexor muscle of the toes. Synonym: aponeurosis plantaris, plantar fascia. (05 Mar 2000) |
| plantar fasciitis | Inflammation of the plantar fascia (fasciitis), the bowstring-like tissue stretching underneath the sole which attaches at the heel. (12 Dec 1998) |
| plantar fibromatosis | Nodular fibroblastic proliferation in plantar fascia of one or both feet; rarely associated with contracture. Synonym: Dupuytren's disease of the foot. (05 Mar 2000) |
| plantar flexion | Turning the foot or toes toward the plantar surface. (05 Mar 2000) |
| plantar interosseous muscle | <anatomy> Three intrinsic muscles of foot; origin, the medial side of the third, fourth, and fifth metatarsal bones; insertion, corresponding side of proximal phalanx of the same toes; action, adducts three lateral toes; nerve supply, lateral plantar. Synonym: musculus interosseus plantaris. (05 Mar 2000) |
| plantar muscle | <anatomy, muscle> Origin, lateral supracondylar ridge; insertion, medial margin of tendo achillis and deep fascia of ankle; action, traditionally described as plantar flexion of foot; many investigators now believe the plantaris muscle to be primarily a proprioceptive organ; nerve supply, tibial nerve. Synonym: musculus plantaris, musculus tibialis gracilis, plantar muscle. (05 Mar 2000) |
| plantar muscle reflex | Flicking the tops of the toes from the plantar surface causes flexion of the toes; a stretch reflex of the flexors of the toes seen in lesions of the pyramidal tracts. See: Starling's reflex. Synonym: plantar muscle reflex, Rossolimo's sign. (05 Mar 2000) |
| plantar quadrate muscle | <anatomy, muscle> Origin, by two heads from the lateral and medial borders of the inferior surface of the calcaneus; insertion, tendons of flexor digitorum longus; action, assists long flexor; nerve supply, lateral plantar. Synonym: musculus flexor accessorius, musculus quadratus plantae, accessory flexor muscle of foot, caro quadrata sylvii, musculus pronator pedis, plantar quadrate muscle, quadrate muscle of sole.
