| compact disks | Computer disks storing data with a maximum reduction of space and bandwidth. The compact size reduces cost of transmission and storage. (12 Dec 1998) |

| compact bone | The compact, noncancellous portion of bone that consists largely of concentric lamellar osteons and interstitial lamellae. Synonym: substantia compacta, compact substance, substantia compacta ossium. (05 Mar 2000) |

| compact torus | <radiobiology> Any of a series of axially symmetric fusion configurations having closed flux surfaces (like a tokamak, not like a mirror machine), but having no material objects piercing the core (as do the toroidal field coils of a tokamak). These devices have an inherently low aspect ratio, approximately unity. The most successful variants are the spheromak and the Field Reversed Configuration. See: low aspect ratio, spheromak, field-reversed configuration. (05 Jan 1998) |
| A disks | The dark-staining anisotropic cross striations in the myofibrils of muscle fibres, comprising regions of overlapping thick (myosin) and thin (actin) filaments. Synonym: A disks, anisotropic disks, Q bands, Q disks. (05 Mar 2000) |
| anisotropic disks | The dark-staining anisotropic cross striations in the myofibrils of muscle fibres, comprising regions of overlapping thick (myosin) and thin (actin) filaments. Synonym: A disks, anisotropic disks, Q bands, Q disks. (05 Mar 2000) |
| Bowman's disks | Disk's resulting from transverse segmentation of striated muscular fibre treated with weak acids, certain alkaline solutions, or freezing. (05 Mar 2000) |
| Ranvier's disks | Tactile nerve endings, of cupped disklike form, in the skin. (05 Mar 2000) |
| rod disks | Membranous disk's of flattened sacs about 14 nm thick that occur in the outer segment of rods of the retina. (05 Mar 2000) |
| cone disks | Membranous disk's of flattened sacs about 14 nm thick that occur in the outer segment of cones of the retina. (05 Mar 2000) |
| sandpaper disks | Disk's of paper coated with various grits of silica; used to abrade or smooth the surface of teeth or dental materials. (05 Mar 2000) |
| Q disks | The dark-staining anisotropic cross striations in the myofibrils of muscle fibres, comprising regions of overlapping thick (myosin) and thin (actin) filaments. Synonym: A disks, anisotropic disks, Q bands, Q disks. (05 Mar 2000) |
| emery disks | Disk's of paper or other materials coated with emery powder used to abrade or smooth the surface of teeth or fillings. (05 Mar 2000) |
