(B) Weeks 4-8, known as the embryonic period, are the time organogenesis occurs and pose the greatest potential for major congenital malformations. All major internal and external organs and systems are formed. ( When teaching a class of nursing students, the nurse asks why the embryonic period (weeks 4-8) of pregnancy is so critical. A gynecoid pelvis most favorable for ...

three ways in which genetic conditions can occur correct answers the variation in the gene that makes it faulty is spontaneous, the faulty gene is passed from parent to child and may directly causea problem that affects the child at birth or later in life, the faulty gene is passed from parent to child and may cause a genetic susceptability to trigger the onset of the disorder germinal period correct answers the period from conception until implantation of the zygote in the wall of the unerus...

Steps of embryonic development Correct Answer-1) Zygote (fertilized egg) undergoes early cleavages -> morula (group of equivalent, undistinguishable cells) 2) As morula grows, cell acquires specific characteristics & some morphological differences (ex. embryonic axes) -> blastula (characterized by presence of hollow cavity, blastocele) 3) Gastrulation (gastrula) originates 3 definitive germ layers (ectoderm, mesoderm, endoderm) 4) Once scaffold & primordial for tissues & organs laid out...
