AN223 Embryology & Development NUI assignment sample Ireland

Embryology is the study of the development of an embryo from fertilization until birth. Development is the process by which an organism grows and changes over time. Development begins with fertilization when the sperm and egg fuse to form a single cell called a zygote. The zygote then divides into two cells, then four cells, and so on, until it forms a ball of cells called a blastocyst. The blastocyst implants in the uterus and begins to grow. The baby develops inside the uterus for about 38 weeks and is born when labor begins.

There are three main stages of embryonic development: the germinal stage, the embryonic stage, and the fetal stage. The germinal stage begins with fertilization and ends with implantation. During this stage, the embryo is a mass of undifferentiated cells. The embryonic stage begins with implantation and ends eight weeks after fertilization. This is when major organ systems begin to form. The fetus stage lasts from eight weeks after fertilization until birth. During this time, the baby continues to grow and develop inside the mother’s womb.

In this section, we are describing some tasks. These are:

Assignment Task 1: Have acquired knowledge of the early events of embryonic development.

There’s a lot to learn about early embryonic development, and acquiring knowledge on the subject can be quite fascinating. Here are some key facts and concepts to keep in mind: 

• Embryonic development begins with fertilization when the sperm and egg fuse to form a single cell called the zygote. 
• The zygote then undergoes a series of cell divisions, known as cleavage, to form a mass of cells called the embryo. 
• At around day 16 of development, the embryo implantation into the lining of the uterus, where it will continue to grow and develop over the next several weeks. 
• During this time, various organs and systems begin to form and mature. 
• By the end of the embryonic stage, all of the major organ systems are present, although they are not yet fully developed. 
• The fetus stage of development begins around eight weeks after fertilization and lasts until birth. 
• During this time, the baby continues to grow and develop inside the mother’s womb.

Assignment Task 2: Have a clear overview of the initial full process of prenatal development.

Prenatal development is the process that starts with fertilization and continues throughout an embryo’s growth and development until birth. Fertilization is when a sperm cell fuses with an egg cell to form a zygote. From there, the zygote will divide into cells that will eventually become the fetus. The entire process of prenatal development generally takes about 38 weeks from fertilization to birth. 

During the earliest stages of prenatal development, the zygote begins dividing into smaller cells called blastomeres. This process, known as cleavage, continues over the next few days as the zygote moves down the fallopian tube towards the uterus. Once in the uterus, implantation occurs – this is when the blastocyst, a hollow ball of cells, attaches to the lining of the uterus. 

After implantation, the cells of the blastocyst begin to differentiate and grow into three different layers: the ectoderm, mesoderm, and endoderm. These layers will eventually give rise to all of the different tissues and organs in the body. The embryonic stage of prenatal development begins at implantation and lasts for about 8 weeks. This is when the embryo undergoes the most rapid growth, and it is during this time that the major organs and systems begin to form.

The fetus stage of prenatal development begins at around 8 weeks after fertilization and lasts until birth. During this time, the baby continues to grow and develop inside the mother’s womb. The fetus grows rapidly during this time, and by the end of the fetal stage, all of the major organs and systems are present and functional.

Assignment Task 3: Have a clear understanding of how the body plans are established early in development.

Yes, it’s important to have a clear understanding of how the body plans are established early in development, as this can help us to better understand diseases and conditions that may develop later in life.

One of the ways that body plans are established is through the process of gastrulation. During gastrulation, cells undergo a process of polarization, where they become organized into distinct layers. These layers will give rise to different tissues and organs in the body.

Another important process for establishing body plans is called induction. Induction occurs when one group of cells (the inductor) signals another group of cells (the target) to adopt a specific fate. For example, during gastrulation, the cells that will become the neural tube will induce the surrounding cells to become the neural crest. The neural crest will then go on to give rise to many different structures, including the brain and nerves.

So, in short, body plans are established through a combination of gastrulation and induction. These processes ensure that cells are properly organized into distinct layers and that they adopt the correct fate. Without proper gastrulation and induction, cells would be randomly organized and would not develop into the proper tissues and organs.

Assignment Task 4: Have acquired knowledge on the basic steps of development of CNS, heart and major vessels, lungs and airways, gastrointestinal system, urogenital system, neck, and face.

The development of the central nervous system (CNS), heart, and major vessels is a complex process that involves many different cell types and signaling molecules. However, there are some basic steps that are common to all of these systems. 

For example, all of these systems begin with the formation of an embryonic structure called the neural tube. The neural tube gives rise to the brain and spinal cord, which make up the CNS. The heart develops from a sheet of tissue called the cardiac crescent, which forms on either side of the embryo. The major vessels develop from other embryonic structures called the aortic arches. 

Lungs and airways develop from another embryonic structure called the pulmonary buds. These buds form in the chest region and eventually grow into the lungs.

The gastrointestinal system develops from a structure called the primitive gut, which forms in the early embryo. This gut eventually grows and forms into the stomach, intestines, and other organs of the GI system. 

The urogenital system develops from a few different embryonic structures. The kidneys develop from structures called the metanephric blastema, while the bladder and urethra develop from the urogenital sinus. The genital organs develop from a structure called the genital tubercle. 

The neck and face develop from a few different embryonic structures as well. The jawbone develops from the first branchial arch, while the rest of the face develops from the second and third branchial arches. The neck develops from a structure called the branchiomeric mesoderm.

Assignment Task 5: Have a clear understanding of basic concepts on causes of occurrence of variations and birth defects and of their importance.

There are many different causes of birth defects. Some are environmental, such as exposure to radiation or toxic chemicals. Others are due to inherited genetic mutations. And still, others occur spontaneously for no known reason.

Despite all the different causes, however, there is one underlying theme that ties them all together: the disruption of normal development. This can be caused by anything from chemical toxins to defective genes. As a result, birth defects can affect any part of the body, from the brain and heart to the arms and legs.

While many birth defects can be treated or corrected after birth, it’s important to have a clear understanding of their origins and importance in order to promote prevention whenever possible.

Assignment Task 6: Have knowledge of the formation of the placenta and its functions.

The placenta is an organ formed during pregnancy that connects the developing fetus to the uterine wall to allow nutrient and waste exchanges. The placenta also produces hormones necessary for fetal development.

The placenta begins to form after implantation, about 8-10 days after fertilization. It starts out as a small, flat structure called the blastocyst and then expands rapidly as new cells are added. By the end of pregnancy, the placenta can weigh up to 2 pounds and be over 12 inches long.

The primary function of the placenta is to transport nutrients from mother to fetus and remove wastes from the fetus. It does this by exchanging oxygen and carbon dioxide between maternal blood and fetal blood. The placenta also produces hormones like estrogen and progesterone, which are necessary for fetal development.
