The zona pellucida is seen as a thick clear girdle surrounded by the cells of the corona radiata. ‘Consider the two major processes in biology - embryology and evolution - that, as applied to human history, must be expressed as tales of sequential development toward greater complexity.’ ‘Historically, the focus of most research on developmental biology of nemerteans was limited to descriptive and experimental embryology and larval development.’ [ em″bre-ol´o-je] the science of the development of the individual during the embryonic stage and, by extension, in several or even all preceding and subsequent stages of the life cycle. In humans, these structures develop into structures of the throat. Human Embryology and Developmental Biology is the study of the fascinating process in humans and animals that turns a single fertilised egg into a whole new individual with all the many specialised cell types. การศึกษาเกี่ยวกับการเติบโตและพัฒนาการของตัวอ่อนของมนุษย์, ที่เกี่ยวกับการเติบโตและพัฒนาการของตัวอ่อนของมนุษย์, ผู้เชี่ยวชาญด้านการเติบโตและพัฒนาการของตัวอ่อนของมนุษย์, Dictionary, Encyclopedia and Thesaurus - The Free Dictionary, the webmaster's page for free fun content, Merck Foundation, MAHE to train embryologists from Asia, Africa, Corrigendum to "Effects of Chronic Exposure to Sodium Arsenite on Expressions of VEGF and VEGFR2 Proteins in the Epididymis of Rats", Missing the point about the beginning of life entirely, Xytex Heads Overseas to Attend the ESHRE Annual Meeting in Germany, Small wonders hatching at Boys & Girls Club. cleavage.
