Morula

Blastulatio: 1, morula; 2, blastula.
Primae segmentationis ovi fertilizati mammaliani stationes. Diagramma: z.p., zona pellucida; p.gl., corpora polaria. Stationes: a, duae cellulae; b, quattuor cellulae; c, octo cellulae; d, e, statio morulae.

Morula (a moro) est embryo in prima vitae statione, qui in cellulis (blastomeris appellatis) in globo solido intra zonam pellucidam contento consistit.[1][2]

Morula a blastocyste differt, quia morula (diebus tertia et quarta post fertilizationem) est massa sedecim cellularum in forma sphaerica consistens, sed blastocystis (diebus quarto et quinto post fertilizationem) cavum intra zonam pellucidam habet cum massa cellulari interiori. Morula, si intacta et continenter inserta est, blastocystis denique fiet.[3]
