1. Morula

   A morula (Latin, morus: mulberry) is an early-stage embryo consisting of a solid ball of cells called blastomeres, contained in mammals, and other animals within the zona pellucida shell. The blastomeres are the daughter cells of the zygote, and when the blastomeres number from 16–32 the ball of cells is called a morula. At the 8-cell stage the blastomeres are round and only loosely adhered. With further division they begin to become flattened, and develop an inside-out polarity that optimises the cell to cell contact.In the human embryo by day four after fertilisation, the morula at about the 32–cell stage begins to take in fluid. The fluid comes about from sodium-potassium pumps (on trophoblasts) that pump sodium into the morula, drawing in water from the maternal environment to become blastocoelic fluid. Hydrostatic pressure of the fluid creates a large cavity in the morula called a blastocoel or blastocyst cavity. Embryoblast cells also known as the inner cell mass form a compact mass of cells at the embryonic pole on one side of the cavity. The trophoblast is organized into a thin sheet of tightly adhered epithelial cells. The embryo is now termed a blastocyst.

1. morula

   A morula is an early stage of embryonic development in animals, occurring after fertilization and before the blastula stage. It is characterized as a solid ball of cells resulting from a series of cleavage divisions of the fertilized egg. The term comes from the Latin word for "mulberry," which the morula is said to resemble.

1. Morula

   A morula is an embryo at an early stage of embryonic development, consisting of cells in a solid ball contained within the zona pellucida. The morula is produced by embryonic cleavage, the rapid division of the zygote. Once the zygote has divided into 32 cells, it begins to resemble a mulberry, hence the name morula. Within a few days after fertilization, cells on the outer part of the morula become bound tightly together with the formation of desmosomes and gap junctions, becoming nearly indistinguishable. This process is known as compaction. The cells of the morula then secrete a viscous liquid, causing a central cavity to be formed, forming a hollow ball of cells known as the blastocyst. The blastocyst's outer cells will become the first embryonic epithelium. Some cells, however, will remain trapped in the interior and will become the inner cell mass, and are pluripotent. In mammals, the ICM will ultimately form the "embryo proper", while the trophectoderm will form the placenta and other extra-embryonic tissues.

1. Morula

   An early embryo that is a compact mass of about 16 BLASTOMERES. It resembles a cluster of mulberries with two types of cells, outer cells and inner cells. Morula is the stage before BLASTULA in non-mammalian animals or a BLASTOCYST in mammals.
