Embryology
Compare embryonic growth and fetal development in single and multiple pregnancies, including the incidence of complications and infant mortality.
During the 4th month, the first month of the second trimester, the greatest amount of fetal growth occurs.
The correct order of the stages in development is typically: 1) germinal stage, 2) embryonic stage, and 3) fetal stage. These stages represent the progression from fertilization of the egg to the formation and growth of the fetus in the womb.
The 3 stages of hair growth are as follows:Anagen- growth stageCatagen- resting stageTelogen- shedding stage
The stages of fetal growth and development are divided into three trimesters. During the first trimester, major organs begin to form. In the second trimester, the fetus grows rapidly, becomes more active, and the organs continue to develop. The third trimester is characterized by further growth and development, as well as the maturation of the fetus's organs in preparation for birth.
Most animals do not pass through four stages of growth. Butterflies, moths and mosquitoes are the common organisms that pass through the four stages of growth.
