During the embryonic period, which development occurs?

Explanation:
During the embryonic period, the main event is organogenesis—the formation of all major organs and body systems. This stage (roughly weeks 3 through 8 after fertilization) lays down the foundations of the brain, spinal cord, heart, limbs, and other essential structures. Hair and nails don’t form yet; those features develop later in the fetal period as the fetus grows. Learning and social skills come after birth, once the nervous system is more developed and experiences shape cognitive and social development.
