Chorion refers to a membrane that becomes attached to the uterine tissues to gather nourishment for the embryo.

Chorion is a term that is used in the field of biology and refers to the outermost of the two fetal membranes that surround and protect the developing embryo in mammals. It is a layer of tissue that is formed from the fertilized egg and is responsible for the exchange of gases, nutrients, and waste products between the embryo and the mother.

Chorion is typically associated with the field of anatomy or physiology, rather than psychology. It is not a term that would typically be used in the context of psychology.
