Fetal Stages Stage Growth Embryo Process Fetus Development 1 9 Months A newly developing human is typically referred to as an embryo until the ninth week after conception, when it is then referred to as a fetus. in other multicellular organisms, the word "embryo" can be used more broadly to any early developmental or life cycle stage prior to birth or hatching. 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.
Premium Vector Fetal Stages Stage Growth Embryo Process Fetus : an animal in the early stages of development that are marked by cleavage, the laying down of the basic tissues, and the formation of primitive organs and organ systems compare fetus. : a tiny young plant within a seed. : a beginning or undeveloped stageused especially in the phrase in embryo. An embryo is a newly fertilized egg (zygote) up till the eighth week of development as it transforms through the morula, blastula, gastrula, and organogenesis stages. An embryo is the early developmental stage of an animal while it is in the egg or within the uterus of the mother. in humans the term is applied to the unborn child until the end of the seventh week following conception. Embryo an organism in its earliest stages of development, especially before it has reached a stage at which it can be distinguished from other species. the human embryo is so called up to the eighth week after fertilization. after that it is called a fetus.
Fetus Development Stages Week By Week An embryo is the early developmental stage of an animal while it is in the egg or within the uterus of the mother. in humans the term is applied to the unborn child until the end of the seventh week following conception. Embryo an organism in its earliest stages of development, especially before it has reached a stage at which it can be distinguished from other species. the human embryo is so called up to the eighth week after fertilization. after that it is called a fetus. As the zygote begins to divide by mitosis, the early multicellular organism is termed an embryo. in humans, the embryonic stage of development is defined as the period from week 5 to week 11 of gestation. after this stage, the embryo transitions into a fetus. In humans, the developing organism is referred to as an embryo from the first cell division until about the eighth week after fertilization. the journey of an embryo starts with fertilization, the fusion of two specialized sex cells, known as gametes—a sperm from the male and an egg from the female. The embryo, which takes the shape of an oval shaped disc, forms an indentation called the primitive streak along the dorsal surface of the epiblast. a node at the caudal or “tail” end of the primitive streak emits growth factors that direct cells to multiply and migrate. When egg and sperm meet, a zygote is formed and quickly begins dividing to become an embryo. as pregnancy progresses, the embryo becomes a fetus. the fetus becomes a neonate or newborn at birth.
