Around week 5, your baby’s brain, spinal cord, and heart begin to develop. Your baby’s brain is part of the central nervous system, which also houses the spinal cord.
What is the first thing that develops in a fetus?
First, the cells of the embryo (called embryonic stem cells) multiply and develop. They become the hundreds of different types of cells needed to make a whole human body. Your baby’s major organs and body parts begin to take shape. The placenta forms during the embryonic stage.
What part of a human develops first?
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.
What develops in the embryonic stage?
The embryonic stage plays an important role in the development of the brain . Approximately four weeks after conception, the neural tube forms. This tube will later develop into the central nervous system including the spinal cord and brain. The neural tube begins to form along with an area known as the neural plate.
Is the heart the first organ to develop in a fetus?
The human heart is one of the first organs to form and function during embryogenesis [1, 2]. By the end of gestational week 3, passive oxygen diffusion becomes insufficient to support metabolism of the developing embryo [3-5], and thus the fetal heart becomes vital for oxygen and nutrient distribution [2].
What is the last organ to form in a fetus?
Almost all organs are completely formed by about 10 weeks after fertilization (which equals 12 weeks of pregnancy). The exceptions are the brain and spinal cord , which continue to form and develop throughout pregnancy. Most malformations (birth defects) occur during the period when organs are forming.
What’s the last thing to develop on a baby?
The reproductive organs also develop, but gender is still difficult to distinguish on ultrasound. By the end of the third month , the fetus is fully formed. All the organs and limbs (extremities) are present and will continue to develop in order to become functional.
When does the fetus develop a heart?
During the first few weeks of pregnancy, your tiny embryo is shaped like a flat disk. By 5 weeks , two tubes that will become the heart have formed. The two tubes fuse together and blood flows through this tubular “heart” as it begins to beat. Between 6 and 7 weeks, the heart tube twists and bends into an S shape.
In which month of pregnancy baby brain develops?
Your fetus will begin the process of developing a brain around week 5 , but it isn’t until week 6 or 7 when the neural tube closes and the brain separates into three parts, that the real fun begins.
Which side is the baby located in the stomach?
The best position for the fetus to be in before childbirth is the anterior position . The majority of fetuses get into this position before labor begins. This position means the fetus’s head is down in the pelvis, facing the woman’s back. The fetus’s back will be facing the woman’s belly.

What is the most critical stage of pregnancy?
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.
What can go wrong in embryonic stage?
Your developing baby is most vulnerable to injury during the embryo stage when organs are developing. Indeed, infections and drugs can cause the greatest damage when exposure occurs two to 10 weeks after conception. Diabetes and obesity can possibly increase your child’s risk of birth defects.
