| 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 |
| plantar syphilid | Dull red papules on the soles in secondary syphilis. (05 Mar 2000) |
| plantar tendon sheath of peroneus longus muscle | <anatomy> The synovial sheath surrounding the tendon of the peroneus longus in its course across the sole of the foot. Synonym: vagina tendinis musculi peronei longi plantaris. (05 Mar 2000) |
| plantar venous arch | The arch formed by the plantar digital veins from the toes which accompanies the plantar arterial arch. Synonym: arcus venosus plantaris. (05 Mar 2000) |
| plantar venous network | A fine superficial venous network in the sole of the foot. Synonym: rete venosum plantare. (05 Mar 2000) |
| proper plantar digital artery | <anatomy, artery> One of the digital branches of the plantar metatarsal arteries. Synonym: arteria digitalis plantaris propria. (05 Mar 2000) |
| proper plantar digital nerves | The ten nerves derived from the common plantar digital nerves; each nerve supplies a plantar quadrant of a toe and part of the dorsal surface of the distal phalanx. Synonym: nervi digitales plantares proprii. (05 Mar 2000) |
| superficial branch of the lateral plantar nerve | <anatomy, nerve> Mostly cutaneous branch to skin of small and lateral half of fourth toes and lateral side of sole of foot, but also supplies the flexor digiti minimi brevis muscle and the most lateral dorsal and plantar interosseous muscles. Synonym: ramus superficialis nervi plantaris lateralis. (05 Mar 2000) |
| superficial branch of the medial plantar artery | <anatomy, artery> Gives rise to superficial digital arteries of medial three toes. Synonym: ramus superficialis arteriae plantaris medialis. (05 Mar 2000) |
