Dr Zahra Mosallanezhad IN THE NAME OF GOD GENITOURINARY TRACT DEVELOPMENT In females the external genitalia gonads and müllerian ducts each derive from different primordia . Behrouz. . Mahmoudi. Introduction. 1. Embryology. Gross Form, Correlation. Errors in development. Structural. Molecular. (Clinical aspects). Real life aspects . (“non medical”). Evolutionary mirror. Development of the oral cavity. The mouth has 2 sources of development:. 1. depression in the . stomodeum. (lined with ectoderm). 2. cephalic end of the foregut(lined with endoderm). These two points are separated by the . A. Urinary System Infections. 1. Any condition that prevents or impairs the normal emptying of the bladder may increase the risk for infection. 2. Although the urinary system is most likely infected from organisms ascending the urethra, it can also be invaded by infections from the bloodstream. From Egg to Embryo. A. Terms. 1. Pregnancy – events occurring from the time of fertilization (conception) until the infant is born. 2. Gestation period – extends from the last menstrual period until birth (280 days). A. Urinary System Infections. 1. Any condition that prevents or impairs the normal emptying of the bladder may increase the risk for infection. 2. Although the urinary system is most likely infected from organisms ascending the urethra, it can also be invaded by infections from the bloodstream. You will notice similarities . among organisms in their . early . stages. . The similar . embryo . development means . they all descend from a common ancestor. The similarities amongst organisms . fades as the organism develops.. 2. Germ cell and fertilization. 3. Blastocyst and implantation. 4. Formation of the germ layer. 5. Differentiation of trilaminar germ and formation of embryo. 6. Fetal membrane and placenta. 7. Twins and multiple birth. Christine Waasdorp Hurtado, MD, MSCS, FAAP.
