| patellar retinaculum | Extensions of the aponeuroses of the vasti medialis and lateralis muscles which pass on each side of the patella, attaching to the margins of the patella and patellar ligament anteriorly, the collateral ligaments posteriorly and the tibial condyles distally; form the anteromedial and (with the fibrous expansion of the iliotibial tract) the anteromedial portions of the fibrous capsule of the knee. See: lateral patellar retinaculum, medial patellar retinaculum. (05 Mar 2000) |
|---|---|
| medial patellar retinaculum | Part of the aponeurosis of the vastus medialis muscle passing medial to the patella to attach to the medial condyle of the tibia, forming the anteromedial aspect of the fibrous capsule of the knee joint. Synonym: retinaculum patellae mediale. (05 Mar 2000) |
| retinaculum | A hook-like structure to which another structure is tethered, in orchids and members of the family Asclepiadaceae, the structure to which pollen masses are attached, in Acanthaceae, the persistent stalk of an ovule. (09 Oct 1997) |
| retinaculum capsulae articularis coxae | One of several longitudinal folds of the articular capsule of the hip joint reflected onto the femoral neck deep to which the retinacular branches of the medial femoral circumflex artery pass to reach the femoral head. Synonym: retinaculum capsulae articularis coxae, Weitbrecht's fibres. (05 Mar 2000) |
| retinaculum caudale | Fibrous bands, remnants of the notochord, that extend from the skin to the coccyx, forming the coccygeal foveola. Synonym: retinaculum caudale, caudal ligament, ligamentum caudale. (05 Mar 2000) |
| retinaculum cutis | One of the numerous small fibrous strands that extend through the superficial fascia attaching the deep surface of the dermis to the underlying deep fascia determining the mobility of the skin over the deep structures; these are particularly well developed over the breast where they are known as suspensory ligaments of the breast; they are also well-developed, but short, in the palms and soles. Synonym: retinaculum of skin. (05 Mar 2000) |
| retinaculum extensorum | A strong fibrous band formed as a thickening of the antebrachial deep fascia, stretching obliquely across the back of the wrist, attaching deeply to ridges on the dorsal aspect of the radius, triquetral and pisiform bones, binding down the extensor tendons of the fingers and thumb. Synonym: retinaculum extensorum, dorsal carpal ligament, ligamentum carpi dorsale. (05 Mar 2000) |
| retinaculum flexorum | <anatomy> A strong fibrous band crossing the front of the carpus and binding down the flexor tendons of the digits and the flexor carpi radialis tendon and the median nerve; in so doing it creates the carpal tunnel. Synonym: retinaculum flexorum, deep part of flexor retinaculum, flexor retinaculum, ligamentum carpi transversum, ligamentum carpi volare, volar carpal ligament. (05 Mar 2000) |
| retinaculum musculorum extensorum inferius | A Y-shaped ligament restraining the extensor tendons of the foot distal to the ankle joint. Synonym: retinaculum musculorum extensorum inferius, cruciate ligament of leg, inferior retinaculum of extensor muscles, ligamentum cruciatum cruris. (05 Mar 2000) |
| retinaculum musculorum extensorum superius | The ligament that binds down the extensor tendons proximal to the ankle joint; it is continuous with (a thickening of) the deep fascia of the leg. Synonym: retinaculum musculorum extensorum superius, ligamentum transversum cruris, superior retinaculum of extensor muscles, transverse crural ligament, transverse ligament of leg. (05 Mar 2000) |
| retinaculum musculorum flexorum | A wide band passing from the medial malleolus to the medial and upper border of the calcaneus and to the plantar surface as far as the navicular bone; it holds in place the tendons of the tibialis posterior, flexor digitorum longus, and flexor hallucis longus. Synonym: retinaculum musculorum flexorum, laciniate ligament, ligamentum laciniatum, retinaculum of flexor muscles. (05 Mar 2000) |
| retinaculum of articular capsule of hip | One of several longitudinal folds of the articular capsule of the hip joint reflected onto the femoral neck deep to which the retinacular branches of the medial femoral circumflex artery pass to reach the femoral head. Synonym: retinaculum capsulae articularis coxae, Weitbrecht's fibres. (05 Mar 2000) |
| retinaculum of flexor muscles | A wide band passing from the medial malleolus to the medial and upper border of the calcaneus and to the plantar surface as far as the navicular bone; it holds in place the tendons of the tibialis posterior, flexor digitorum longus, and flexor hallucis longus. Synonym: retinaculum musculorum flexorum, laciniate ligament, ligamentum laciniatum, retinaculum of flexor muscles. (05 Mar 2000) |
| retinaculum of skin | One of the numerous small fibrous strands that extend through the superficial fascia attaching the deep surface of the dermis to the underlying deep fascia determining the mobility of the skin over the deep structures; these are particularly well developed over the breast where they are known as suspensory ligaments of the breast; they are also well-developed, but short, in the palms and soles. Synonym: retinaculum of skin. (05 Mar 2000) |
| retinaculum tendinum | A ligamentous structure to restrain tendons, such as the flexor or extensor retinacula, or the annular parts of the digital fibrous sheaths. (05 Mar 2000) |
