| posterior tibial recurrent artery | <anatomy, artery> An inconstant branch of the posterior tibial artery which ascends anterior to the popliteus muscle, anastomoses with branches of the popliteal artery, and sends a twig to the tibiofibular joint. Synonym: arteria recurrens tibialis posterior. (05 Mar 2000) |
|---|---|
| posterior tibial veins | Venae comsitantes of the posterior tibial artery that join those of the anterior tibial artery to form the popliteal vein. Synonym: venae tibiales posteriores. (05 Mar 2000) |
| second tibial muscle | An inconstant muscle, of small size, arising from the back of the tibia and inserted into the articular capsule of the ankle joint. Synonym: second tibial muscle. (05 Mar 2000) |
| subcutaneous bursa of tibial tuberosity | The bursa located superficial to the tibial tuberosity, either subcutaneous or subfascial. Synonym: bursa subcutanea tuberositatis tibiae. (05 Mar 2000) |
| superior tibial articulation | The plane synovial joint between the lateral condyle of the tibia and the head of the fibula. Synonym: articulatio tibiofibularis, superior tibial articulation, superior tibiofibular joint, tibiofibular articulation. (05 Mar 2000) |
| tibial | 1. Of or pertaining to a tibia. 2. Of or pertaining to a pipe or flute. <zoology> Tibial spur, a spine frequently borne on the tibia of insects. Origin: L. Tibialis, fr. Tibia the shin bone; also, a pipe or flute, originally made of a bone: cf. F. Tibial. <anatomy> A tibial bone; a tibiale. Source: Websters Dictionary (01 Mar 1998) |
| tibial arteries | The anterior and posterior arteries created at the bifurcation of the popliteal artery. The anterior tibial artery begins at the lower border of the popliteus muscle and lies along the tibia at the distal part of the leg to surface superficially anterior to the ankle joint. Its branches are distributed throughout the leg, ankle, and foot. The posterior tibial artery begins at the lower border of the popliteus muscle, lies behind the tibia in the lower part of its course, and is found situated between the medial malleolus and the medial process of the calcaneal tuberosity. Its branches are distributed throughout the leg and foot. (12 Dec 1998) |
| tibial border of foot | The inner border of the foot extending from heel to the great toe. Synonym: margo medialis pedis, margo tibialis pedis, tibial border of foot. (05 Mar 2000) |
| tibial bowing | <radiology> Anterior bowing, OI, hypophosphatasia, thanatophoric dwarfism, neurofibromatosis, may lead to if fractured, doesn't heal normally, posterior bowing, often bilateral, due to foetal malposition, fracture will heal normally (12 Dec 1998) |
| tibial collateral ligament | <anatomy> The broad fibrous band that passes from the medial epicondyle of the femur to the medial margin and medial surface of the tibia; the medial meniscus is attached to its deep surface; it is continuous with (a thickening of) the fibrous capsule of the knee joint. Synonym: ligamentum collaterale tibiale, medial ligament of knee. (05 Mar 2000) |
| tibial communicating nerve | <anatomy, nerve> Arises from the tibial in the popliteal space, passes down the calf between the two heads of the gastrocnemius and unites in the middle of the leg with the communicating branch of the common peroneal to form the sural nerve, distributed to the skin of the distal and lateral surfaces of the leg and ankle. Synonym: nervus cutaneus surae medialis, medial cutaneous nerve of leg, popliteal communicating nerve, tibial communicating nerve. (05 Mar 2000) |
| tibial crest | The sharp subcutaneous ridge of the tibia that extends from the tuberosity to the anterior part of the medial malleolus. Synonym: margo anterior tibiae, anticnemion, shin, tibial crest. (05 Mar 2000) |
| tibial intertendinous bursa | <anatomy> The bursa between the tibial collateral ligament of the knee joint and the tendons of the sartorius, gracilis, and semitendinosus muscles. Synonym: bursa anserina, tibial intertendinous bursa. (05 Mar 2000) |
| tibial nerve | <anatomy, nerve> The medial terminal branch of the sciatic nerve. The tibial nerve fibres originate in lumbar and sacral spinal segments (l4 to s2). They supply motor and sensory innervation to parts of the calf and foot. (12 Dec 1998) |
| tibial phenomenon | Dorsal flexion of the great toe, sometimes of the entire foot, in a paralysed limb when the extremity is drawn up against the body, flexing both knee and hip. Synonym: tibial phenomenon. (05 Mar 2000) |
