Study Notes
Session Overview
- Active Learning Embryology session on August 6, 2024, from 10:30 am to 12:00 pm.
- Directed by James Proffitt, PhD, from the Department of Cellular & Molecular Medicine.
- Session employs a flipped classroom format, emphasizing discussion and large group engagement.
Instructional Methods
- Primary method: IM07 - Discussion, Large Group (more than 12 participants).
- Resources include written or visual media relevant to embryology concepts.
Learning Objectives
- Assess the impact of teratogen exposure and congenital infections during various developmental stages.
- Identify involved germ layers in specific clinical cases.
- Predict anatomical structures affected by damage to specific germ layers.
- Classify types of twinning based on morphology and timing.
- Relate foundational embryology concepts to clinical scenarios.
Key Concepts to Review
- Distinction between Embryological vs. Gestational Developmental Timelines.
- Recognize critical periods in embryonic development; identify three stages most susceptible to teratogen-induced injuries.
- Understand germ layers and categorize anatomical structures accordingly.
Types of Twinning
- Dizygotic: Two separate eggs fertilized.
-
Monozygotic:
- Dichorionic Diamniotic: Two chorions, two amniotic sacs.
- Monochorionic Diamniotic: One chorion, two amniotic sacs.
- Monochorionic Monoamniotic: One chorion, one amniotic sac.
Developmental Timeline Key Events
-
Week 1:
- Rule of 1s: One embryonic precursor (embryoblast), one placental precursor (trophoblast), one fluid-filled sac (blastocoel).
-
Week 2:
- Rule of 2s: Two embryonic layers (epiblast, hypoblast), two placental contributors (cytotrophoblast, syncytiotrophoblast), two extraembryonic sacs (amnion, primary yolk sac).
-
Week 3:
- Rule of 3s: Three germ layers (ectoderm, mesoderm, endoderm), three key structures (primitive streak, notochord, neural plate), three extraembryonic membranes (amnion, secondary yolk sac, allantois).
-
Week 4:
- Dorsal fold (neural groove), ventral fold (body cavities), craniocaudal fold (fetal positioning due to head growth and elongation).
Preparation for Session
- Review lecture notes and previous embryology recordings to grasp core concepts and enhance discussion readiness.
