How does an embryo looks like?

In humans, an embryo typically looks like a small, round structure with a cluster of cells that will eventually develop into different tissues and organs. As development progresses, the embryo takes on a more recognizable human form with distinct features.

Where are new somites formed?
New somites are formed from the presomitic mesoderm, which is located at the posterior end of the embryo. Sequentially, cells from the presomitic mesoderm undergo a process called somitogenesis to form new somites, contributing to the segmented structure of the developing embryo.
What embryonic structure give rise to the centrum?
Vertebral Discs Help the Centrum rise.
What is the first organ to form in an embryo?
