EMBRYOLOGY. GAMETOGENESIS, FERTILISATION, CLEAVAGE. Dr. Andrea D. Székely. Semmelweis University Faculty of Medicine Department of Anatomy, Histology and Embryology Budapest. EMBRYOLOGY. Definition: the study of the origin and development of an organism. Prenatal period: before birth. 38 weeks from conception to birth (average) “fetal” age.
Human Embryo (a) At 18 days after conception the embryo consists of 3 layers of cells: endoderm, mesoderm, and ectoderm. Thickening of the ectoderm leads to the development of the neural plate. (b) The neural groove begins to develop at 20 days.
Introduction. This lecture will cover male and female gametogenesis and fertilisation. IN development 1 embryonic cell (zygote) will produce about 1013 (100,000,000,000,000) cells in the adult at any one time (over time with cell death and ongoing replacement this is substantially more). Historic drawing of human oocyte and spermatozoa.
Embryology. Ontogeny – study of complete life cycle of an organism. It consist of prenatal development and post natal growth. Prenatal stage- from fertilization to birth. -zygote-embryo- fetus (studied in embryology) Post natal stage-growth and maturity after birth. - new born-infant –child- adult.
The lecture will be followed by a practical class introducing online resources for independent study and working through similar embryology concepts. Printable Lecture Page (http://php.med.unsw.edu.au/embryology/index.php?title=Foundations_Lecture_-
The 3D Atlas of Human Embryology comprises 14 user-friendly and interactive 3D-PDFs of all organ systems in real human embryos between stage 7 and 23 (15 till 60 days of development), and additional stacks of digital images of the original histological sections and annotated digital label files.
