The best position for your baby to be in for labour and birth is head down, facing your back – so that their back is towards the front of your tummy. This is called the occipito-anterior position. It allows them to move more easily through the pelvis.

Cleavage serves two main purposes: it forms a multicellular embryo and organizes the embryo into developmental regions. When the outer cells of the blastocyst contact cells lining the uterus, the blastocyst embeds in the lining, a process called implanation.

Maternal Effect Genes in Development Gastrulation, through massive cell movements and rearrangements, places the three germ layers in their canonical positions and shapes them into a body plan with organ rudiments. In all animals, gastrulation starts after and absolutely requires activation of the zygotic genome.

(T/F) The placenta is composed solely of embryonic membranes. The (allantois/amnion) encases the young embryonic body in a fluid-filled chamber that acts to protect the developing embryo against trauma.

The first trimester is the most crucial to your baby’s development. During this period, your baby’s body structure and organ systems develop. Most miscarriages and birth defects occur during this period.

Week 5 is the start of the “embryonic period.” This is when all the baby’s major systems and structures develop. The embryo’s cells multiply and start to take on specific functions. This is called differentiation. Blood cells, kidney cells, and nerve cells all develop.

From week 33 the baby ‘s brain and nervous system are fully developed, and the bones are continuing to harden. At 36 weeks, the baby’s lungs are fully formed and ready for breathing after birth.

According to them, the fetus which is 16 weeks can be regarded as human being because of ensoulment. It follows from this that one is authorized to refer to fetus which is 16 weeks or more as human being.

The heart is the first organ to form during development of the body. When an embryo is made up of only a very few cells, each cell can get the nutrients it needs directly from its surroundings.

The umbilical cord is a soft ‘bendy’ tube from the placenta to the navel (or tummy button) of the fetus. There is a sac (a bag) of thin skin filled with fluid protecting the skin of the developing baby. The baby can move around safely inside the mother for 9 months until he or she is ready to be born into our world.

But here are six simple, research-supported ways to help boost your baby’s brain development in utero.

1. Take a Hike. Well, it doesn’t have to be a hike, a 30-minute walk will do the trick!
2. Food as Medicine.
3. Supplement A Healthy Diet.
4. Read to Your Bump.
5. Get More Sleep.
6. Get Geared Up.

The embryo is lying on its back with his head on the right side. His heart is the blue area. The umbilical cord stretches from the developing baby’s abdomen to the placenta, and the red and blue colors within the cord represent blood going to and from the placenta, where it picks up oxygen and nutrients.

When the fetus is in the back-to-back or posterior position, the pregnancy bump may feel squishy. A woman may also notice kicks around the middle of the belly, and some people may also see an indentation around their belly button. When the fetus is in the anterior position, a woman may feel more kicks under the ribs.

If your baby is head down and facing your back (OA position), you’ll probably feel kicks under your ribs. You’ll also be able to feel the hard, rounded surface of your baby’s back, which will be on one side of your belly.

Added to that, it might sometimes feel squishy and other times rock hard. When your pregnant belly feels rock hard and firm all over, it’s usually because you’re having a contraction. This is nothing to worry about. It’s normal for the uterine muscles to contract and harden as a practice for true labour.

Can crying and depression affect an unborn baby? Having an occasional crying spell isn’t likely to harm your unborn baby. More severe depression during pregnancy, however, could possibly have a negative impact on your pregnancy.

Because it’s normal for a fetus’s lungs to be filled with fluid, a fetus can’t drown in the womb. If there is a problem with the placenta or umbilical cord, there’s no other way for a developing baby to breathe.
