In mammals, the blastula forms the blastocyst in the next stage of embryonic development. Here the cells in the blastula arrange themselves in two layers: the inner cell mass and an outer layer called the trophoblast . The inner cell mass is also known as the embryoblast; this mass of cells will go on to form the embryo. At this stage of development, the inner cell mass consists of embryonic stem cells that will differentiate into the different cell types needed by the organism. The trophoblast will contribute to the placenta and nourish the embryo
What else can I help you with?
Which sequence represents the correct order of processes that result in the formation and development of an embryo?
Fertilization, cleavage, blastulation, gastrulation, organogenesis.
What is the point where two nerve processes meet?
The point where two nerve processes meet is called a synapse. At the synapse, a chemical or electrical signal is transmitted from one neuron to another, allowing for communication between nerve cells in the nervous system.
The restoration of homeostasis after an injury involves two related processes?
The two related processes involved in the restoration of homeostasis after an injury are inflammation and tissue repair. Inflammation helps to remove damaged cells and pathogens, while tissue repair involves the regeneration and remodeling of tissues to restore function. Together, these processes work to heal the body and return it to a state of balance.
Theory that processes that can be seen today also occurred in the past?
Uniformitarianism is the theory that the same geological processes we see happening today have been shaping the Earth's surface over millions of years. This idea, popularized by geologist Charles Lyell in the 19th century, suggests that the present is the key to the past when studying Earth's history. By examining current processes, scientists can better understand how landscapes, rock formations, and fossils were formed in the past.
Which two processes are included in the prenatal development of a single human embryo?
The two processes included in prenatal development of a human embryo are cleavage, where the initial cell divides into multiple cells, and gastrulation, when the cells organize into the three germ layers of the embryo: ectoderm, mesoderm, and endoderm.
Is blastulation and gastrulation one and the same thing?
No, blastulation and gastrulation are distinct processes in embryonic development. Blastulation is the formation of the blastula from the zygote, while gastrulation is the process during which the three germ layers (ectoderm, mesoderm, and endoderm) are formed from the blastula.
Which sequence represents the correct order of processes that result in the formation and development of an embryo?
Fertilization, cleavage, blastulation, gastrulation, organogenesis.
What are the two processes in a cycle pattern rather than vasoconstriction happening?
vasoconstriction and vasolidation
What is blastulation explain briefly?
Blastulation is the process of the cleavage subdividing the mass of the zygote until a cluster of cells known as blastula are formed
What is produced by the end of blastulation?

What does it mean if two things are happening simultaneously?
If two things are happening simultaneously, it means that they are happening at the same time. For example, if you said something in response to someone and the person next to you said the same thing at the same exact time, that would be happening simultaneously.
Is blastulation and gastrulation one and same thing?
Blastulation is when the cells move to form a hollow "ball". Gastrulation is when it bends upon itself to make 3 layers, called the endoderm, the mesoderm, and the ectoderm.
One of the two geologists that proposed that the earth has changed over millions of years and the processes that caused the change are still happening?
James Hutton
What is the significance of politics?
Politics is the study of government processes. Studying politics helps us to understand what is happening with the government and why it is happening.
Why we here now in planet earth?
We are the result of the processes that have happened and are happening on our planet.
What are the satges of growth and development?
the stages of growth are: gametogenesis fertilization cleavage or segmentation blastulation gastrulation organogenesis
How does the amount of yolk affect blastulation?
The amount of yolk present in an egg can affect blastulation by influencing the cleavage pattern and rate of cell division. Eggs with more yolk tend to have slower and asynchronous cleavage, which can impact the formation of the blastula. Higher yolk content may also affect the size and nutrition available to the developing embryo during blastulation.
