| sedimentation velocity | The rate of movement of a substance, typically a macromolecule, in centrifugation; these centrifugation studies provide data on the structure of the macromolecule. (05 Mar 2000) |

| erythrocyte sedimentation rate | <investigation> A test that measures the rate at which red blood cells settle through a column of liquid. A non-specific index of inflammation. Acronym: ESR (11 Nov 1997) |
| zeta sedimentation ratio | The ratio of the zetacrit to the haematocrit, normally 0.41 to 0.54 (41 to 54%); it is a sensitive indicator of the erythrocyte sedimentation rate (ESR) and, unlike the latter, is unaffected by anaemia, which tends to elevate the ESR. (05 Mar 2000) |
| articular meniscus | A crescent-shaped intra-articular fibrocartilage found in certain joints. Synonym: meniscus articularis, articular crescent, intra-articular cartilage. (05 Mar 2000) |
| carman meniscus sign | <radiology> Saemicircular (meniscoid) configuration of gastric ulcer seen in profile with compression, suggestive of malignancy see: gastric ulcers (12 Dec 1998) |
| medial meniscus | <anatomy> A flat disc-shaped ligament which stabilises and supports the inner aspect of the knee joint. Commonly injured in knee sprains. (27 Sep 1997) |
| meniscus | Origin: NL, from Gr, dim. Of mhnh the moon. 1. A crescent. 2. <optics> A lens convex on one side and concave on the other. 3. <anatomy, ornithology> An interarticular synovial cartilage or membrane; especially, one of the intervertebral synovial disks in some parts of the vertebral column of birds. Converging meniscus, Diverging meniscus. See Lens. Source: Websters Dictionary (01 Mar 1998) |
| meniscus articularis | A crescent-shaped intra-articular fibrocartilage found in certain joints. Synonym: meniscus articularis, articular crescent, intra-articular cartilage. (05 Mar 2000) |
| meniscus lateralis | A flat disc-shaped ligament which stabilises and supports the outer aspect of the knee joint. Not as commonly injured as the medical meniscus ligament in knee sprains. (27 Sep 1997) |
| meniscus lens | A lens having a spherical concave curve on one side and a spherical convex curve on the other. Synonym: meniscus. (05 Mar 2000) |
| meniscus medialis | <anatomy> A flat disc-shaped ligament which stabilises and supports the inner aspect of the knee joint. Commonly injured in knee sprains. (27 Sep 1997) |
| meniscus tactus | A specialised tactile sensory nerve ending in the epidermis, characterised by a terminal cuplike expansion of an intraepidermal axon in contact with the base of a single modified keratinocyte. Synonym: meniscus tactus, Merkel's corpuscle, Merkel's tactile cell, Merkel's tactile disk, tactile disk. (05 Mar 2000) |
| periscopic meniscus | A lens designed to correct spherical aberration and coma (q.v.). Synonym: periscopic meniscus. (05 Mar 2000) |
| converging meniscus | A convexoconcave lens in which the power of the convexity exceeds that of the concavity. Synonym: positive meniscus. (05 Mar 2000) |
| positive meniscus | A convexoconcave lens in which the power of the convexity exceeds that of the concavity. Synonym: positive meniscus. (05 Mar 2000) |
