What's the difference between polygon and undecagon?

Polygon


Definition:

  • (n.) A plane figure having many angles, and consequently many sides; esp., one whose perimeter consists of more than four sides; any figure having many angles.

Example Sentences:

  • (1) Gap junctions were of different sizes and frequently composed of a small number of connexons organized in polygonal aggregates or linear arrays.
  • (2) The isolated outer sheath was observed as a triple-layered, closed vesicle carrying a polygonal array by electron microscopy.
  • (3) Electron microscopically, the tumor cell nuclei were oval or polygonal and sometimes slightly invaginated, with a few prominent nucleoli.
  • (4) Delimitation of the pathological process in the lung is characterized by an increase in the number of T- and B-lymphocytes and considerable predominance of polygonally shaped cells with cytoplasmic outgrowths of different lengths and their subsequent replacement by a cell form transitory between T- and B-lymphocytes.
  • (5) At day 12-15, some nodules consisting of polygonal cells were formed in all culture conditions, and these nodules were mineralized 2-3 days later.
  • (6) The majority of the choline acetyltransferase-immunoreactive neurons had fusiform, oval, or polygonal somata with somatic diameters greater than 20 microns and contained deeply invaginated nuclei surrounded by copious cytoplasm.
  • (7) One type of cells had polygonal morphology, showed density-dependent contact inhibition at confluence in vitro, showed lectin-binding characteristics of endothelium (but only moderate positivity for factor VIII antigen), demonstrated induction of gamma-glutamyl transpeptidase when exposed to astrocyte-conditioned media, and responded to insulin by a pronounced increase in DNA synthesis.
  • (8) The first type included large multipolar neurons with triangular or polygonal perikarya and typically 3-5 dendrites emerging from the poles of each cell.
  • (9) Type II neurons had multipolar or polygonal cell bodies, which measured an average 31 micrometer by 43 micrometer and emitted four to seven primary dendrites.
  • (10) "En face" views of the epithelial cells showed capping protein distributed in a polygonal pattern coincident with cell boundaries in intestinal epithelium, sensory epithelium of the cochlea, and the pigmented epithelium of the retina and at regions of cell-cell contact between chick embryo kidney cells in culture.
  • (11) Polygonal, foamy macrophages were found in 12 cases.
  • (12) The subcultured HNC and ADPKD cells retained characteristic epithelial polygonal and elongated shape and positive immunofluorescent staining for cytokeratin.
  • (13) The slightly prominent apices of the superficial epithelial cells are more or less polygonal in shape and covered with short microvilli among which small granules as possible morphological expression of a secretory activity are detectable.
  • (14) Initially, they grew as individual polygonal cells, tending to form tight confluent monolayers with poorly defined intercellular boundaries.

Definition:

  • (n.) A figure having eleven angles and eleven sides.
