morula

 [mor´u-lah]
a solid mass of cells (blastomeres) resembling a mulberry, formed by cleavage of a zygote (fertilized ovum).

mor·u·la

(mōr'ū-lă),
The solid mass of blastomeres resulting from the early cleavage divisions of the zygote. In oocytes with little yolk, the morula is a spheroid mass of cells; in forms with considerable yolk, the configuration of the morula stage is greatly modified.
[Mod. L. dim. of L. morus, mulberry]

morula

/mor·u·la/ (mor´u-lah)
1. the solid mass of blastomeres formed by cleavage of a zygote.
2. an inclusion body seen in circulating leukocytes in ehrlichiosis.

morula

(môr′yə-lə, môr′ə-)
n. pl. moru·lae (-lē′)
The spherical embryonic mass of blastomeres formed before the blastula and resulting from cleavage of the fertilized ovum.

mor′u·lar adj.
mor′u·la′tion n.

morula

[môr′ələ] pl. morulas, morulae
Etymology: L, morulus, blackberry
a solid, spherical mass of cells resulting from the cleavage of the fertilized ovum in the early stages of embryonic development. It represents an intermediate stage between the zygote and the blastocyst and consists of blastomeres that are uniform in size, shape, and physiological capabilities. morular, adj.

morula

An early stage in the development of the embryo at which it consists of a solid spherical ball of apparently identical cells.

morula

a solid ball of cells resulting from cleavage of a fertilized ovum. It is formed of a mass of BLASTOMERES which subsequently form a BLASTULA.

morula

2. a cluster of organisms appearing as an inclusion in the cytoplasm of circulating leukocytes infected by Ehrlichia spp.
