Why Are Certain Developmental Stages More Vulnerable?
Certain developmental stages are more vulnerable to toxic effects due to the rapid cell division and differentiation occurring at these times. During embryogenesis, for example, cells are forming critical structures and organs. Interruptions during this period can lead to significant malformations or functional deficits. The concept of critical windows is essential in toxicology, as it helps identify when interventions might be most effective in preventing damage.
