What makes embryology unique?
- ) Embryology dictates whether an organism survives in life (foundation).
- ) Embryology studies the starting point.
- ) Understanding of function is better upon understanding of embryology.
State the Central Paradox of Life.
How is it that a single fertilized egg van give tise to a complex, multicellular organism?
Study of the embryo, from zygote to state resembling sexually mature individual.
Embryology
Steps in embryonic development.
Cleavage, gastrulation, neurulation, organogenesis, histogenesis
What is histogenesis?
Differentiation and specialization of cells.
Study of heredity and transmission of traits from parents to offspring.
Genetics
Embryology + postnatal development
Developmental biology
Developmental Genetics is
Study of the effects of genes/heredity to the development of an organism, translation from genotype to phenotype.
Importance of embryology.
- ) foundation of modern science
- ) accounts for unity in diversity
- ) appreciation and better understanding of higher forms of biology
- ) major courses in biology
- ) answers questions on what makes animals unique
Neoplastic growth
Abnormal proliferation of cells
Tissue repair
Repair of tissues from molecular to organismic level
Metamorphosis
Process by which an animal transitions from larvae to adult
Regeneration
Regrowth of body parts from pieces of an organism
