| cuboidal epithelium | Simple epithelium with cells appearing as cubes in a vertical section but as polyhedra in surface view. (05 Mar 2000) |
| cuboideonavicular joint | A fibrous joint between adjacent parts of the cuboid and navicular bones; occasionally a synovial cavity is found here as an extension of the cuneonavicular joint. (05 Mar 2000) |
| cuboideonavicular ligaments | Ligament uniting the cuboid bone with the navicular bone. See: dorsal cuboideonavicular ligament, plantar cuboideonavicular ligament. Synonym: ligamentum cuboideonavicular. (05 Mar 2000) |
| cuboidodigital reflex | Flexion of the toes on tapping over the cuboid bone; almost identical with Guillain-Barre reflex, and fundamentally similar to Rossolimo's reflex. Synonym: metatarsal reflex. (05 Mar 2000) |
| cucullate | Hooded, hood-shaped. (09 Oct 1997) |
