Question

Quizplus · Accepted Answer

The amniotic cavity is the fluid-filled sac that surrounds the embryo/fetus and provides shock absorption.

Answer: L 
 Implantation is the process during which the fertilized egg (zygote) attaches to the wall of the uterus and begins to develop.

Answer: O 
 The yolk sac is a membranous sac that provides nutrients for the developing embryo during the early stages of pregnancy.

Answer: M 
 Organogenesis is the process of organ formation during embryonic development.

Answer: D 
 The placenta is an organ that connects the developing fetus to the uterus, allowing for nutrient uptake, waste elimination, and gas exchange.

Answer: E 
 The fetus is the developing organism from the ninth week of gestation until birth.

Answer: N 
 Fertilization is the fusion of an egg and sperm to form a zygote.

Answer: F 
 The embryo is the developing organism from the time of fertilization until the end of the eighth week of gestation.

Answer: C 
 The blastocyst is a stage of embryonic development that occurs after the morula and before implantation, characterized by the formation of an inner cell mass and a fluid-filled cavity.

Answer: H 
 The mesoderm is one of three primary germ layers that forms during gastrulation and gives rise to muscle, bone, blood, and connective tissue.

Answer: G 
 The ectoderm is one of three primary germ layers that forms during gastrulation and gives rise to the skin, nervous system, and other tissues.

Answer: I 
 The endoderm is one of three primary germ layers that forms during gastrulation and gives rise to the gut lining and associated organs.

Answer: B 
 The morula is a stage of embryonic development that occurs after fertilization and before the blastocyst, characterized by a solid ball of cells.

Answer: J 
 Histogenesis is the process of tissue formation during embryonic development.
