Apr 12, 2023 · During each week of pregnancy, your baby is growing. Here’s a look at what medical terms like embryo and fetus mean in terms of development.
An embryo is the initial stage of development for a multicellular organism. In organisms that reproduce sexually, embryonic development is the part of the life cycle that begins just after fertilization of the female egg cell by the male sperm cell.
Jul 6, 2017 · An embryo refers to the early developmental stage of eukaryotic organisms following the fertilization of an egg (derived from a female) by sperm (derived from a male) as a method of sexual reproduction.
Aug 13, 2023 · An embryo refers to the early developmental stage of a multicellular organism that follows fertilization. This stage represents a crucial juncture in the life cycle, transitioning from a single fertilized cell into a complex organism with specialized tissues and structures.
Jul 8, 2024 · What Is an Embryo? An embryo is the early stage of a baby’s development during pregnancy. The first stage is the fertilized egg (zygote). It divides to become a blastocyst and travels down the fallopian tube to the uterus, where it may implant to establish the pregnancy.

v. t. e. Human embryonic development or human embryogenesis is the development and formation of the human embryo. It is characterised by the processes of cell division and cellular differentiation of the embryo that occurs during the early stages of development.
Dec 15, 2015 · We all know the story - egg meets sperm, gets fertilised, becomes a zygote. Once the cells start dividing, they clump and regroup, until at some point they start morphing into organs and body parts.
