Lecture 1
Female Reproductive Tract Anatomy

A cow is a bulls way of making another bull.

Learning Objectives
  • To learn the different structures and
    nomenclatures for the parts of the female
    reproductive system.
  • To learn the basic functions for the different
    parts of the tract and how they work together.

Ovary - Primary Sex Organ
  • Functions
  • Hormonal
  • Estrogen
  • Progesterone
  • Female gamete
  • Oocyte

Functions of the Uterus
  • Muscle contractions
  • Transport sperm
  • Expel fetus and placenta
  • Absorption and phagocytosis
  • Partially prepares sperm for fertilization
  • capacitation
  • Provides environment for embryo and fetal growth
  • Hormone production
  • Prostaglandin F2a production

  • Bicornuate
  • poorly to moderately developed uterine horns

Functions of the Cervix
  • Transport of sperm
  • Barrier to sperm (species dependent)
  • Reservoir for sperm
  • Blocking bacterial invasion during pregnancy
  • Birth canal

45
COW
Uterine Body
  • Cervix is composed of thick connective tissue
  • Mucus is secreted near the time of breeding and
    ovulation.

Cervix
Cow has 4-5 annular rings

Functions of the Vagina
  • Copulatory organ
  • Glands secrete lubrication
  • Birth canal
  • Glands secrete pheremones

Function of External Genitalia
  • Labia
  • Closes entrance to vagina
  • Clitoris
  • Female sensory organ

Phenomena For Fertility
  • vagina dentata - a vagina with teeth
  • female bedbug - no vagina
  • hysterectomy - if woman went to long without
    becoming pregnant then uterus would wonder in
    body causing hysteria and other distresses
  • hyena - clitoris is very large and looks like the
    male penis female also has a false scrotum
    (labia) female is the dominate sex and produces
    more testosterone than male
