PSY354H5 Lecture Notes - Lecture 8: Conceptus, Micropenis, Pelvic Floor
Document Summary
Genes guide development of structure of the fetus. What are the steps and sequence that occurs. Listing series of steps and how things get differentiated. Fertilization sperm must go through 2 important processes: Not all sperm capacitate at the same time; tends to vary by time; once capacitated, it has to have a good sense of where the egg is and the egg sends out chemical attraction to. ; if not enough digestive enzymes, then the sperm can not penetrate the layer of the egg. There"s going to be mixing of genetic material between sperm and egg. What allows for sperm to continue to habitate in the egg is the increase of calcium ions in the conceptus stage. Increase of calcium ions means allowing genetic material exchange to occur. In order to figure if healthy fertilization has occur, need to see multiple cell division. Start off with conceptus and see if genetic material starts to induce cell division.
