Apuntes

Universidad de Puerto Rico en Bayamón Departamento de Biología Biología del Desarrollo - BIOL 3028 Segundo Semestre 2025-2026 Answer the following questions: Tricuspid Atresia 1. Tricuspid Atresia originates during which period of embryonic development? Between 5-8 weeks of gestation, when atrioventricular valves and endocardial cushions are forming 2. In Tricuspid Atresia, the absence or incomplete development of the tricuspid valve directly disrupts communication between which two heart chambers? It disrupts blood flow between the right atrium and right ventricle due to absence of tricuspid valve. 3. Which of the following "compensatory" openings is essential for fetal survival in Tricuspid Atresia, allowing blood to pass from the right atrium to the left atrium? Comunicación interauricular y comunicación interventricular 4. A failure in the process of delamination _ _ prevents the tissue from separating to form the valve leaflets in Tricuspid Atresia, creating a solid barrier? 5. Which signaling pathway, crucial for communication between the endocardium and myocardium, is often interrupted in Tricuspid Atresia, affecting the formation of valve tissue? Notch signaling pathway Spi...
