- 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

Q
Notochord
A
P C F P I N D

- **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
