Morula

5 The process is repeated again and again, so that the two cells are succeeded by four, eight, sixteen, thirty-two, and so on, with the result that a mass of cells is found within the zona striata, and to this mass the term morula is applied (Fig. 9). ❋ Unknown (1918)

A solid mass of cells is formed at the beginning, called a morula, Figure 1. ❋ Unknown (1906)

This is called the morula (= mulberry-embryo) on account of its resemblance to a mulberry or blackberry. ❋ Ernst Heinrich Philipp August Haeckel (1876)

From early afternoon yesterday, I lay on my bed reading and just out the glass doors in the male morula tree was a big spotted eagle owl attempting to get some shelter from the relentless rain. ❋ Lauri (2010)

A fertilized egg morula, blastulocyst, very early embryo has no brain. ❋ Unknown (2005)

We lost two on Friday, one other was at the morula stage. ❋ Brile (2002)

Internal timing now somehow tells the morula to change shape from a compact ball of sixty or so cells to a fluid-filled sphere, the “blastocyst,” housing those previously starved cells destined to become the embryo. ❋ GERALD L. SCHROEDER (2001)

The morula, as the cluster of cells is called at this stage, floats freely in the uterus until seven or eight days after ovulation, absorbing its needed nutrients from uterine secretions. ❋ GERALD L. SCHROEDER (2001)

Fruits such as baobab (Adansonia digitata) and morula (Sclerocarya birrea) are exceptionally rich in the vitamin. ❋ Unknown (1999)

If now these developmental processes do not depend on chance, but, on the contrary, are rooted in the nature of the animal cell itself, we have no reason for inferring from the recurrence of a similar segmentation-process, morula, blastula, and gastrula in all classes of the animal kingdom the common descent of all animals from one blastula-like or gastrula-like ancestral form. ❋ Unknown (N/A)

The morula, a compact mulberry-like congeries of segmentation-cells, corresponded to the synamoeba, or earliest association of undifferentiated amoeboid cells to form the first multicellular organism. ❋ Unknown (N/A)

In 1838 Bischoff [268] observed segmentation in the mammalian ovum, and the whole course of segmentation in the ovum of the rabbit from the 2-celled to the morula stage was carefully described and figured by Barry [269] in ❋ Unknown (N/A)

The procession advanced; one by one the eggs were transferred from their test-tubes to the larger containers; deftly the peritoneal lining was slit, the morula dropped into place, the saline solution poured in … and already the bottle had passed, and it was the turn of the labellers. ❋ Huxley, Aldous, 1894-1963 (1932)

The cells of the morula are at first closely aggregated, but soon they become arranged into an outer or peripheral layer, the trophoblast, which does not contribute to the formation of the embryo proper, and an inner cell-mass, from which the embryo is developed. ❋ Unknown (1918)

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). ❋ Unknown (1918)

At first the cells present the appearance of a bunch of grapes or the grains of a mulberry, the morula stage; the growth proceeds rapidly, a cavity forms itself inside and the blastosphere stage is reached. ❋ 1840-1916 (1913)
