| 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) |
| Winslow's ligament | <anatomy> The cordlike ligament that passes from the lateral epicondyle of the femur to the head of the fibula. Synonym: ligamentum collaterale fibulare, lateral ligament of knee, Winslow's ligament. (05 Mar 2000) |
| conjugate ligament | <anatomy> A ligament in some mammals which is the homologue of the intra-articular ligament present in the joints between the heads of the ribs and the vertebrae. Synonym: ligamentum conjugale. (05 Mar 2000) |
| Wrisberg's ligament | <anatomy> The band that passes posterior to the posterior cruciate ligament extending between the medial condyle of the femur and the posterior crus of the lateral meniscus. Synonym: ligamentum meniscofemorale posterius, ligamentum cruciatum tertium genus, ligamentum menisci lateralis, Wrisberg's ligament. (05 Mar 2000) |
| conoid ligament | <anatomy> The medial part of the coracoclavicular ligament that attaches to the conoid tubercle of the clavicle. Synonym: ligamentum conoideum. (05 Mar 2000) |
| coracoacromial ligament | <anatomy> The heavy arched fibrous band that passes between the coracoid process and the acromion above the shoulder joint; the osseofibrous arch thus formed prevents upward dislocation of the shoulder (glanohumeral) joint. Synonym: ligamentum coracoacromiale. (05 Mar 2000) |
| coracoclavicular ligament | <anatomy> The strong ligament that unites the clavicle to the coracoid process; it is subdivided into the conoid ligamentum and the trapezoid ligamentum. The free upper limb is passively suspended from the clavicular "strut" by the coracoclavicular ligament; the ligament also plays an important role in preventing dislocation of the acromioclavicular joint. Synonym: ligamentum coracoclaviculare, Caldani's ligament. (05 Mar 2000) |
| coracohumeral ligament | The ligament that passes from the base of the coracoid process to the greater tubercle of the humerus. Synonym: ligamentum coracohumerale. (05 Mar 2000) |
| corniculopharyngeal ligament | <anatomy> An elastic band connecting the tip of the corniculate (Santorini's) cartilage and the lamina of the cricoid cartilage and continuing into the pharyngeal mucosa covering the cricoid lamina. Synonym: ligamentum cricopharyngeum, corniculopharyngeal ligament, cricosantorinian ligament, jugal ligament, ligamentum corniculopharyngeum, ligamentum jugale. (05 Mar 2000) |
| coronary ligament of knee | Portions of the articular capsule of the knee joint which connect the circumference of the menisci with the margins of the condyles of the tibia. (05 Mar 2000) |
| coronary ligament of liver | Peritoneal reflections from the liver to the diaphragm at the margins of the bare area of the liver. Synonym: ligamentum coronarium hepatis. (05 Mar 2000) |
| costoclavicular ligament | <anatomy> The ligament that connects the first rib and the clavicle near its sternal end; limits elavation of shoulder (at sternoclavicular joint). Synonym: ligamentum costoclaviculare, rhomboid ligament. (05 Mar 2000) |
| costocolic ligament | <anatomy> A triangular fold of peritoneum attached to the left flexure of the colon and to the diaphragm, on which rests the inferior pole or extremity of the spleen. Synonym: ligamentum phrenicocolicum, costocolic ligament. (05 Mar 2000) |
