Title: Animal Science/Dairy Science 434


1
Animal Science/Dairy Science 434
  • Reproductive Physiology
  • Lecture 1 Introduction, Female Anatomy

2
What is happening in this image?
3
Instructions
  • Graded exercise (5 points)
  • On the card provided, list 3 things that you
    observe or know are occurring in the scene. (2
    minutes)
  • Print your name at the top
  • Form groups of 4 or 5 (List the names in the
    group on your card).
  • Take 2 minutes to discuss the scene and make a
    group list of what is occurring in the scene.

4
Potential Ways To Interpret Image
  • Superficial
  • Looking into each others eyes
  • Touching
  • Physiological changes
  • Heart rates increasing
  • Increased blood flow to reproductive organs
  • Lubrication of vagina, clitoral enlargement,
    contractions of uterus
  • Erection of penis, contractions of epididymis

Laboratories
  • Tuesday, Wednesday or Thursday
  • Room 134 Animal Science
  • 330 - 530

434 Web Site Modifications
  • Updates may occur daily.
  • Lecture outlines and labs are currently for last
    year
  • 2004 lecture updates are usually done by 815 the
    day of lecture
  • 2004 lab material will be updated by the time of
    Tuesdays lecture.

10
Web Page Techniques
  • Netscape 4.5 or better
  • Internet Explorer 5.0 or better
  • Will work best from a campus networked computer
  • essential for video clips in WebCT
  • Display set for 800 X 600
  • Frames were used in page construction
  • Printing (check FAQ)
  • movement within web site
  • Reload button (for lab computers)
  • the site is continually being changed

Grading (Tentative)
The final grade will be curved but generally ends
near the following percentages A (100-93), AB
(88-93), B (80-88), BC (79-70), C (69-60), D
(59-50), F (lt50).
16
Case or Problem Based Approach
  • Dear Uncle Ed
  • I turned my heifers out this fall with a bull.
    The veterinarian determined most were pregnant in
    January. The heifer in the center of the picture
    was however not pregnant. What could be the
    problem?
  • Your nephew,
  • John

17
How do you approach a case?
  • What information is relevant and what is not?
  • What do you need to know?
  • Where will you find this information?
  • Team or Group responsibilities
  • What will each member do?
  • Time limits

18
Lecture 1
Female Reproductive Tract Anatomy
19
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.

  • Barrier to sperm (species dependent)
  • Reservoir for sperm
  • Blocking bacterial invasion during pregnancy
  • Birth canal

48
COW
Uterine Body
  • Cervix is composed of thick connective tissue
  • Mucus is secreted near the time of breeding and
    ovulation.

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
