endash;(L. morus = mulberry) early stage of development (12-15 cells) when conceptus is a solid ball of cells, further cell division forms the blasocyst.
a little mulberry; a term applied by E. Haeckel to a free-swimming stage of a coral embryo. (The term does not apply to human development where the blastomeres are surrounded by a zona pellucida and the anlage of the blastocoele develops with the very first subdivisions of the ovum; cf. blastomeric ovum).
Cells resulting from the early division of the fertilized egg at the beginning of pregnancy.
(Latin, morula = mulberry) early stage in development (week 1) where the cells have divided to produce a solid mass of cells with a "mulberry" appearance. This stage is followed by formation of a cavity in the mass (blastocyst stage). (More? Week 1 Notes | Week 1 Early Cell Division)
An early stage of embryonic development where a solid spherical mass of cells have formed from the fertilized ovum. It is an intermediate stage between the zygote and the blastocyst.
stage during early embryogenesis in which the embryo resembles a mulberry (roughly 16 to 32 cells).
a solid mass of cells that develops about six days after fertilization of an egg cell.
The fertilized egg after a few days of development when it forms a ball of cells.
Developmental stage of the fertilized ovum in which there is a solid mass of cells.
The preimplantation embryo 3-4 days after fertilization, when it is a solid mass composed of 12-32 cells ( blastomeres). After the eight-cell stage, the cells of the preimplantation embryo begin to adhere to each other more tightly, becoming "compacted". The resulting embryo resembles a mulberry and is called a morula (Latin: morus = mulberry).
A mulberry-shaped collection of cells produced by the mitotic divisions of a zygote.
A globular, solid mass of cells formed by the cleavage of a zygote (a fertilized egg and the stages that follow it). This stage precedes the blastula.
Early in development, a cluster of dividing cells or blastomeres. Morula is derived from morus meaning raspberry .
Latin for mulberry. The stage of embryonic development at which cells are too numerous to count easily but before the blastocyst stage. Morulae usually contain from 16 to 60 cells.
An early stage of embryonic development (roughly 16-64 cells) at which the embryo is a solid spherical mass of cells, resulting from the early cleavage divisions of the zygote; so called because of its resemblance to a “little mulberry” (in Latin, morula).
(L. morus, mulberry). A mass of blastomeres on the 3rd to 4th day after fertilization just as the developing human enters the uterus.
A very early stage of pre-natal mammalian development. This stage starts when the zygote has developed into a mass of 16 cells. This is typically 4 days after fertilization, and about 10 days before it becomes implanted in the wall of the womb.
The solid-ball stage of the pre-emplantation embryo. PICTURE
16 celled embryo. Derived from the Latin for Mulberry.
A stage of embryo development after 4 days of culturein vivo (inside the body). Between the 8-cell stage and the blastocyst stageof development, all the cells of the embryo merge together, this is referredto as a morula.
endash;(L. morus = mulberry) early stage of development (12-15 cells) Followed by formation of a cavity in the mass (blastocyst stage). (More? Week 1 Notes)
morus - mulberry]. The early stage of a blastula in which the solid mass of blastomeres resembles a mulberry in appearance. This occurs immediately before the blastocoel appears, forming the blastula.
The globular mass of cells formed by the cleavage of the fertilized egg in the first stages of its development.
bisc333 a solid mass of blastomeres that forms when the zygote splits; develops into the blastula www.cogsci.princeton.edu/cgi-bin/webwn
A compact sphere of 16 blastomeres that forms at about 3-4 days after fertilization.
Solid ball of embryonic cells produced by rapid division of fertilized ovum; precedes blastocyst stage.
A morula (Latin "morus", mulberry) is an embryo at an early stage of embryonic development, consisting of approximately 12-32 cells (called blastomeres) in a solid ball contained within the zona pellucida. The morula is produced by embryonic cleavage, the rapid division of the zygote. After reaching the 16-cell stage, the cells of the morula differentiate.
