| contractile proteins | Proteins which participate in contractile processes. They include muscle proteins as well as those found in other cells and tissues. In the latter, these proteins participate in localised contractile events in the cytoplasm, in motile activity, and in cell aggregation phenomena. (12 Dec 1998) |
| contractile ring | The equatorial ring of microfilaments that diminishes in diameter probably both by contraction and disassembly as cytokinesis proceeds. (18 Nov 1997) |
| contractile stricture | A stricture due to the presence of contractile tissue which may be dilated but soon returns. Synonym: contractile stricture. (05 Mar 2000) |
| contractile vacuole | A specialised vacuole of eukaryote cells, especially Protozoa, that fills with water from the cytoplasm and then discharges this externally by the opening of a permanent narrow neck. Function is probably osmoregulatory. (18 Nov 1997) |
| peritubular contractile cells | Flattened smooth muscle-like cell's of mesodermal origin that lie just outside the basal lamina of the seminiferous tubule. Synonym: peritubular contractile cells. (05 Mar 2000) |
