The longest period of prenatal development is the _____ period.

Question

BlackTom AI · Accepted Answer

The question asks about the longest period of prenatal development.
Option 1: proximodistal. This describes the directional pattern of development from the center of the body outward, not a time period. It pertains to the sequence of growth rather than length of prenatal stages, so it does not answer the question about duration.
Option 2: germinal. The germinal period spans roughly the first two weeks after conception, including fertilization and implantation. While important, it is relatively short and clearly not the longest prenatal stage.
Option 3: fetal. The fetal period begins around week 9 after conception and continues until birth, encompassing roughly the remaining seven months of gestation. This is the longest continuous stage of prenatal development, involving rapid growth and maturation of existing structures rather than initial formation.
Option 4: embryonic. The embryonic period lasts from about week 3 to week 8 post-conception, when major organs and systems begin to form. Although critically important, it is shorter than the fetal period and thus not the longest.
