Embryology concerns:

Embryology concerns:

• A. Subdivision of developmental anatomy, concerns developmental changes that occur before birth.
• B. Subdivision of gross anatomy focusing on birth processes.
• C. The study of entire organ systems.
• D. The study of age-related changes.

Answer: (A)

Embryology is the study of development before birth, tracing how a zygote becomes an embryo and then a fetus. It belongs to developmental anatomy, which covers how organisms grow and change over time. The key idea is its prenatal focus—fertilization, cell division, germ-layer formation, and organ development that occur before birth. This sets it apart from gross anatomy, which maps visible structures (often in the adult), and from studying entire organ systems or aging, which deal with later life changes.
