Phases of Fertilization

PPFMOZ

Pork Pies Feed Many Old Zookeepers

  1. Passage - sperm undergoes capacitation via FPP + heparin, corona cells disperse via hyaluronidase + tail
  2. Penetration - sperm binds to ZP3, acrosome reaction occurs via hyal + acrosin, zona rxn via lysosome enzymes
  3. Fusion - sperm/oocyte membranes fuse, sperm contents enter 
  4. Meiosis II - oocyte rxn, chromosomes decondense to make pronucleus, mature oocyte and 2nd polard body form
  5. Ootid Formation - sperm nucleus becomes pronucleus, egg w/ both pronuclei = ootid
  6. 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

  1. Hatching - blastocyst growth breaks ZP
  2. Adhesion - blastocyst adheres to endometrium
  3. Differentiation - trophoblast > cyto and syncytio
  4. Erosion/Embedding - syncytio- erodes endometrium
  5. Lacuna Formation - lacunae form in syncytio-
  6. Plug - fibrinous plug closes endometrium
  7. Lacune Networks - lacunae join to form network
  8. Uteroembryonic Circulation - syncytio- erodes maternal vessels, blood enters lacunae
  9. Epithelial Repair - plug degrades, endometriual epi repairs
  10. Villi - primary chorionic villi develop

Notochord

P C F P I N D

People Can't Find Pens In North Dakota

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