- Among the germ layers and developmental structures below: What is/are the FORMED ANATOMICAL ORGAN/PART (of the infant)? Indicate if it disappears or dissolved in the process of development. •amniotic cavity •blastula •cleavage •ectoderm •embryoblast •embryonic disc •endoderm •epiblast •fertilization •gametes •gastrulation •hypoblast •intermediate mesoderm •lateral plate mesoderm •mesoderm •morula •neural crest cells •neurulation •notochord •occipital somites •paraxial mesoderm •primitive node •primitive streak •trophoblast •yolk sacPrenatal development is the time from fertilization to birth and includes both embryonic and fetal periods. It is divided into period of three calendar months called trimester. Describe the major events of each trimester.During the organogenesis stage, several of the five essential developmental processes take place. Choose two of these essential processes and describe how and when they occur during the organogenesis stage. Be specific about the cells, tissues, and organs involved and the results.
- Please match the early developmental structure on the left with the human structure it develops into on the right: inner cell mass of the blastocyst Choose ] [Choose ] the brain ectoderm of the gastrula the skin & nervous system the placenta the embryo the heart and lungs anterior neural tube of the embryo [Choose ] trophoblast of the blastocyst [ Choose ]Fill in the blank: All essential external and internal body parts are formed during the ___________________ stage of development.Directions: Arrange in correct order the development of human embryo from fertilization until birth. Write the number from 1 to 6 in the box provided. ON: Blastocyst continues its journey down the fallopian tube until it reaches the uterus for implantation. The union of the sperm and the egg cell forming a zygote. Embryo begins to differentiate. The zygote travels down the fallopian tube while undergoing several mitotic divisions. When an embryo reaches the 8th week until birth, it is now referred to as a fetus where it remains in the mother's womb. The blastocyst cells form an inner and outer cell layer of the embryo and will later on develop other structure like the placenta. The formation of different cell layers (gastrulation).
