Document Summary

Sperm that come after this, can"t bind to sperm receptors: no chance of fertilization if sperm haven"t bind sperm receptors before this point, prevents polyspermy, magnum (2-3 hrs) Infundibulum to magnum: where albumin is produced- rest of albumin is produced here. This all must be carried down the reproductive tract: 50% of the egg is made in the magnum. Albumin is produced all of the time in an actively egg producing female: magnum is producing albumin 24 hours a day and storing them until the yolk comes along. In uv junction, serve as sperm storage units. Isthmus (1-2 hours, 1 hr 14 min average: magnum isthmus, thick circular muscle, need a lot of concentrated muscle to squeeze things forward down the reproductive tract, less secretory tissue than magnum. See portion that the crystal is put on is put on the outer shell membrane by the isthmus just before it passes to the uterus.
