Textbook Question

Problems involving the formation of the chorion would affect
(a) The embryo’s ability to produce blood cells
(b) The formation of limbs
(c) The embryo’s ability to derive nutrition from the mother
(d) Lung formation
(e) The urinary system

Verified step by step guidance

Understand the role of the chorion: The chorion is an extraembryonic membrane that plays a critical role in forming the placenta, which facilitates the exchange of nutrients, gases, and waste between the mother and the embryo.

Analyze the options provided: Each option relates to a specific function or developmental process in the embryo. Consider which of these functions is directly influenced by the chorion.

Evaluate option (a): The production of blood cells is primarily associated with the yolk sac and later the liver and bone marrow, not the chorion.

Evaluate option (c): The chorion is directly involved in the embryo's ability to derive nutrition from the mother, as it contributes to the formation of the placenta.

Conclude based on the analysis: Problems with the chorion would most likely affect the embryo's ability to derive nutrition from the mother, as this is its primary function.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Chorion

The chorion is an essential extraembryonic membrane in mammals that plays a critical role in the development of the placenta. It facilitates the exchange of nutrients and gases between the mother and the embryo, thus supporting embryonic growth and development. Any issues with chorion formation can directly impact the embryo's ability to receive necessary nutrients and oxygen.

Nutritional Support in Embryonic Development

During embryonic development, the embryo relies on the mother for nutrition, primarily through the placenta formed by the chorion. This nutritional support is vital for cellular growth, organ development, and overall viability of the embryo. Disruptions in this process can lead to developmental issues or failure to thrive.

Embryonic Development Stages

Embryonic development occurs in distinct stages, including the formation of key structures such as the heart, limbs, and organs. Each stage is dependent on proper signaling and nutrient supply, which are influenced by the chorion and placenta. Understanding these stages helps in recognizing how problems in chorion formation can lead to specific developmental abnormalities.
