Sorry, no etymologies found.


  • Fluid collects between the trophoblast and the greater part of the inner cell-mass, and thus the morula is converted into a vesicle, the blastodermic vesicle (Fig. 10).

  • There might be here and there abnormalities due to accident or to faulty arrangements and malnutrition of the blastodermic cells; but these were of the individual, and not general.

  • Baer grappled anew with the theory of "blastodermic foliation."

  • The section below is a small portion of the blastodermic area. b.d., blastoderm.

    Text Book of Biology, Part 1: Vertebrata

  • While the blastula is being folded into a cup at the vegetal pole of its axis, the difference in the size of the blastodermic cells increases (Figure 1.38 D, E); it is most conspicuous when the invagination is complete and the segmentation-cavity has disappeared (Figure 1.38 F).

  • The less clear entodermic cells (i) are distinguished at first by their rounder shape and darker nuclei from the higher, clearer, and longer entodermic cells (e), afterwards both are greatly flattened, the inner blastodermic cells more than the outer.

  • In this way each blastodermic cell becomes a ciliated cell.

    The Evolution of Man — Volume 1

  • This layer of cells is called the germinal membrane (or blastoderm); the homogeneous cells which compose its simple structure are called blastodermic cells; and the whole hollow sphere, the walls of which are made of the preceding, is called the blastula or blastosphere.

    The Evolution of Man — Volume 1

  • A fine, long, thread-like process, a sort of whip or lash, grows out of each blastodermic cell, and this independently executes vibratory movements, slow at first, but quicker after a time

    The Evolution of Man — Volume 1

  • The blastosphere may grow and expand by the blastodermic cells (at the surface of the sphere) dividing and increasing, and more fluid is secreted in the internal cavity.
