En esta lección vamos a hablar de como un embrión se desarrolla en las primeras ocho semanas de embarazo.
Part of the inner cell mass of the blastocyst, the embryonic disk is the cellular framework that begins embryonic development; the nervous system develops from ectoderm of this.
The developing baby after the first 8 weeks of development up to birth.
Also called spontaneous abortion, a miscarriage is when the embryo is expelled from the uterus.
A tube formed from the ectoderm of the blastocyst that serves as the framework for the development of the central nervous system (brain and spinal cord).
The X & Y chromosomes that when paired determine the gender of the child and carry other genetic traits as well; XX = female while XY = male.
