Hi,where does fetal pole form, how does fetal pole originate? If gestational sac is not showing fetal pole, then where is this fetal pole possibly be?

[@animatedbiologywitharpan]

The fetal pole is a term used in early pregnancy ultrasound scans. It refers to the first visible sign of a developing embryo, which includes the fetal body and heartbeat. This typically becomes detectable at around 6 weeks of gestation. Ultrasound imaging of the fetal pole is an essential milestone in confirming a viable pregnancy and assessing its progress. If you have specific questions or concerns about the fetal pole, it's best to consult with a healthcare professional for personalized guidance.

Can u plz eloborate the Difference betwen mesoderm and extra embryonic mesoderm?

[@asphantom640]

Extra embryonic mesoderm forms in the 2nd week between the cytotrophoblast and the exocoelomic cavity while mesoderm is formed in the 3rd week from epiblast cells between the endoderm and ectoderm

[@eidhassanwarsame9258]

also the difference is mesoderm is inner cells while other one is outer cell

Is allantois formed in human embryo and what archenteron

[@animatedbiologywitharpan]

Yes, the allantois is present in humans during early embryonic development. It is one of the extraembryonic membranes that play a role in the development of the circulatory system and later becomes part of the umbilical cord. However, it is important to note that the allantois in humans is a transient structure that largely disappears as development progresses.

[@animatedbiologywitharpan]

The archenteron is a structure that forms during the early stages of embryonic development in animals, including humans. It is the primitive gut or embryonic digestive tube that develops from the gastrula, which is the stage following gastrulation in embryogenesis. The archenteron eventually gives rise to the future digestive tract, including the stomach, intestines, and associated structures. This process is fundamental in the formation of the body plan during embryonic development.

Where the amniotic fluid and yolk sac goes

[@animatedbiologywitharpan]

Thanks for this question. I should have made it clear in my video.During fetal development, the amniotic fluid serves multiple purposes. It provides protection and cushioning to the developing fetus, maintains a stable environment, helps with lung development, aids in regulating temperature, and allows for movement and growth. After birth, the amniotic fluid is typically expelled from the newborn's body, and its fate varies depending on the circumstances. It can be reabsorbed by the mother's body, expelled naturally as postpartum discharge, or in medical settings, it may be collected and discarded as medical waste.
As for the yolk sac, it plays a crucial role in early embryonic development, providing essential nutrients to the developing embryo. However, in humans, the yolk sac does not serve as a direct source of nutrition throughout the entire gestation period. Instead, as the embryo grows and the placenta develops, the yolk sac diminishes in size and is eventually incorporated into the fetal digestive system. Its remnants, known as the vitelline duct, typically disappear or form small structures in the body, having no functional significance after birth.
