Document Summary

Structure of wall of oviduct also helps oocyte move toward uterus: cilia will push the fluid and egg to uterus. Smooth muscle in the wall of oviduct to provide peristalsis. Exterior covering is visceral peritoneum, supported by mesoalpinx. Isthmus is the bridge of the oviduct that connects to the uterus, it becomes quite thin. Fundus rounded region superior to the entrance of the uterine tubes; isthmus narrowed region btwn body and cervix. Cervical canal (cavity of cervis) communicates with vagina via external os; cervical canal communicates with the cavity of the uterine body via the internal os. Cervical glands in mucosa of cervical canal, secrete mucus that fills the cervical canal and covers the external os; blocks the spread of bacteria from vagina to uterus. Less vicious at midcycle to allow sperm to pass through. Passage way for delivery of infant, exit of menstrual flow, and entry of sperm.
