| 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 ligaments | The counterparts in the foot of the palmar ligaments in the hand. Synonym: ligamenta plantaria, accessory plantar ligaments, Cruveilhier's ligaments, glenoid ligament. (05 Mar 2000) |
| plantar metatarsal artery | <anatomy, artery> One of four branches of the plantar arterial arch that divide into plantar digital arteries to supply the toes. Synonym: arteria metatarsea plantaris. (05 Mar 2000) |
| plantar metatarsal ligaments | Fibrous bands connecting the plantar aspects of the bases of the metatarsals. Synonym: ligamenta metatarsalia plantaria. (05 Mar 2000) |
| plantar metatarsal veins | Veins receiving the plantar digital veins and draining in turn into the deep plantar venous arch, which empties into the medial and lateral plantar veins. Synonym: venae metatarseae plantares. (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. (05 Mar 2000) |
| plantar reflex | The response to tactile stimulation of the ball of the foot, normally plantar flexion of the toes; the pathologic response is Babinski's sign. Synonym: sole reflex. (05 Mar 2000) |
| plantar space | One of four areas between fascial layers in the foot, where pus may be confined when the foot is infected. (05 Mar 2000) |
| plantar surface of toe | plantar surface of toe |
