En esta lección vamos a discutir el desarrollo de las tres capas germinales, que dan lugar a los órganos y tejidos del embrión.
The first three layers of tissue that develops in the embryo as it starts to form (ectoderm, mesoderm, and endoderm).
The outer germ layer that forms the nervous system, skin, melanocytes and lenses of the eyes.
The middle germ layer that forms muscles (cardiac, smooth, skeletal), mesenchyme, blood vessels, and mesenteries.
The innermost germ layer that forms the digestive tract, respiratory tract, endocrine glands, auditory systems, and urinary bladder.
A general term to describe the splitting or breaking apart of an object or molecule; in embryology this is when the zygote starts to divide into multiple cells.
After the morula forms, each new cell that divides is called a blastomere.
The process of cells taking on specific forms and functions, also called specialization of cells.
When an organism develops a specific shape.
