What's the difference between tessera and tesserae?

Tessera


Definition:

  • (n.) A small piece of marble, glass, earthenware, or the like, having a square, or nearly square, face, used by the ancients for mosaic, as for making pavements, for ornamenting walls, and like purposes; also, a similar piece of ivory, bone, wood, etc., used as a ticket of admission to theaters, or as a certificate for successful gladiators, and as a token for various other purposes.

Example Sentences:

  • (1) Transmission electron microscopy shows calcification in close association with coarse collagen fibrils on the outer side of a tessera, but such fibrils are absent from the cartilaginous matrix along the under side of tesserae.
  • (2) If so, the cap could be considered a thin veneer of bone atop the calcified cartilage of the body of a tessera.
  • (3) The outer zone of tesserae, the cap, is composed of calcified tissue which appears to be produced by perichondrial fibroblasts more directly, i.e., without first differentiating as chondroblasts.
  • (4) Individual tesserae develop peripherally at the boundary between cartilage and perichondrium.
  • (5) Calcospherites and hydroxyapatite crystals similar to those commonly seen on the surface of bone are present on the outer surface of the tessera adjacent to the perichondrium.
  • (6) By scanning electron microscopy it was observed that outer and inner surfaces of tesserae differ in appearance.
