Phases of Fertilization

Pork Pies Feed Many Old Zookeepers
- Passage - sperm undergoes capacitation via FPP + heparin, corona cells disperse via hyaluronidase + tail
- Penetration - sperm binds to ZP3, acrosome reaction occurs via hyal + acrosin, zona rxn via lysosome enzymes
- Fusion - sperm/oocyte membranes fuse, sperm contents enter
- Meiosis II - oocyte rxn, chromosomes decondense to make pronucleus, mature oocyte and 2nd polard body form
- Ootid Formation - sperm nucleus becomes pronucleus, egg w/ both pronuclei = ootid
- Zygote Formation - pronuclei fuse to form zygote, cleavage spindle forms, cross-over shuffles genes

- days 5-14 (~1 day per step), via hormones, growth factors, steroids
- Hatching - blastocyst growth breaks ZP
- Adhesion - blastocyst adheres to endometrium
- Differentiation - trophoblast > cyto and syncytio
- Erosion/Embedding - syncytio- erodes endometrium
- Lacuna Formation - lacunae form in syncytio-
- Plug - fibrinous plug closes endometrium
- Lacune Networks - lacunae join to form network
- Uteroembryonic Circulation - syncytio- erodes maternal vessels, blood enters lacunae
- Epithelial Repair - plug degrades, endometriual epi repairs
- Villi - primary chorionic villi develop
Notochord

- Process - notochordal process forms via mesenchymal migration/invagination from primitive pit ectoderm
- Canal - prim. pit extends into process to form notochordal canal cranially > prechordal plate
- Fusion - notochordal process floor fuses with endoderm
- Degeneration - holes form btwn canal and yolk sac below
- Plate - holes fuse, canal floor disappears, remaining ceiling of n. process = notochordal plate
- Infolding - craniocaudal infolding of n. plate cells forms notochord
- Neurenteric Canal - caudal part of notochord remains open briefly as neurenteric canal
- Detachment - notochord detaches from yolk sac endoderm, which is again continuous
