You might think that the embryonic stage is just a little sidestep in human development. But let me tell you, it’s actually a crucial phase where everything happens (even more than when Kanye West tweets something controversial).
What is the Embryonic Stage?
The embryonic stage is basically the second week after fertilization until around eight weeks of gestation (which can feel like an eternity if you’re pregnant and have morning sickness). During this time, a tiny embryo develops into what will eventually become your adorable baby.
The Beginning of Life
From a biological standpoint, at conception, sperm and egg unite to form fertilized eggs which contain all genetic information necessary for life which divides to create cells and tissues needed to develop complex beings. This occurs during embryogenesis causing changes in gene expression leading to morphological differentiation from fetuses.
After fertilization happens with female gamete meeting sperms,a multitude of chemical reaction takes place making way for blastocyst formation (consisting Insulated inside three cellular layers viz., Endoderm(makes internal organs), Mesoderm (forms muscles,bones & circulatory system) and Ectoderm(out coating of body including nervous system)). The blastocysts gets attached or implanted onto uterine wall through trophoblasts grown using many signaling mechanisms.
What Happens During This Phase?
So why is everyone so hyped about the embryonic stage? Well, lots of stuff happens during this period! It makes Harry Potter learning how to cast spells look like child’s play:
- Rapid Cell Division: Right off the bat (no pun intended) those cells start dividing — it’s like an epic game of mitosis.
- Formation organ rudiments: Structures likes heart tube,nervous system folds toward forming central neural groove and skeletal build up start to take shape.
- Formation of essential cells: Things like blood cells, certain neurons get developed during this phase without which life would never be same as it is.It’s living proof that the early embryonic bird gets the worm.
What can go wrong?
As with any important medical process, there are always a few hiccups along the way. During embryogenesis time any anomaly occurring in cell growth and development stage will lead to irregularities ranging from irreversible damage,reduced organial functioning,worst case scenario miscarriage or still birth. Bad genes,breeding among families,frequent alcohol consumption and careless lifestyle can become risk factors making hurdles for healthy baby formation possible thus these things should always be kept in check before planning pregnancy.
If you’re one of those deeply emotional people who cry when watching puppies learn how to walk no judgement, then you might want to brace yourself for some heart-wrenching facts. In fact, saying that critical time for formation of organs is Embryogenesis itself won’t be correct because developing fetus heart holds more importance than other structures previously formed .
When does heart development begin?
Any cardiovascular aficionado worth their salt knows that cardiac development begins at around day 16-18 after fertilization (approximaately after three weeks). By five weeks gestation (which basically feels like eternity) a beating heart can usually be detected on an ultrasound at being just larger than paprika seed!!.
And Then There Was Blood Flow!
Watching your unborn child’s heart beat through an ultrasound machine will probably make even hardest person turn into mush (I mean seriously people wept over a lion king character dying,human emotions are weird) But after fourth week completion energy derived from canalizing first ever red cell generation causes flow inside vascular networks comprising umbilical cord & arteries allowing crucial nutrients needed taken by embryo cutting inhibitions of curbed blood flow.
How Heart Forms
As with all amazing things, the development of the heart is a bit complicated. Here’s how it breaks down:
The early embryo starts out with little strings of tissue called somites.What can be thought as prehistoric gills for action-eating carnivorous fish ( where only few species thrived on Earth ) come to play and develop progressively similar vessels known as endothelial tubes which eventually grow connected through conductive tissues inside muscular nodules encircled by lumen allowing further communication within body organs ( endocardial trabeculae) till matured functioning muscle contracts from head towards feet in coordinated fashion.Little by little precursors like auricles ,atria and sinuous forms ventricle portion de novo initiating process leading full grown fully functional heart (which bring plenty tears into expecting mother’s eyes once held onto baby post delivery).,
Can Anything Go Wrong?
Yes just like every other organ formation,(I’m starting to think that life really knows how to punk us sometimes) several risks loom threatening normal growth. The cause might be at molecular genetic basis or result from environmental factors faced during pregnancy such as direct exposure over alcohol,certain bacterial infections,taking certain harmful medications amongst others.One should never neglect regular check-ups,toxicity levels of work place/home ambience,having counselling sessions if disturbed mentally/physically so as not invite any cardiac defects whose consequences may not seem benign keeping danger high during gestational period.
The embryonic stage beings are nothing but miracles on legs willing I mean trying to stand up. During this time when the cellular changes occur rapidly,embryogenesis takes places providing very short opening taking shape needing nurture and care thus parents should always take good care both physically &
mentally maintaining proper cautionary measures what they do,because we wouldn’t want those tiny homebrewed gems coming into world facing any complications. So here’s to the miracle of life and all the amazing things our bodies can do!
