Histology of reproductive tissues in the non-pregnant female
Objectives:
1. Recognise the preantral primordial, primary, secondary follicle and the tertiary antral follicle
of the ovary Identify the cell layers of the follicle Identify the cell layers of the uterine tube and the uterus and describe how they change during the
oestrous cycle.

3. OVIDUCT 2 SLIDE 194 Examine slide 194.
Identify: Ampulla, Isthmus and fimbria (if present)
Make low and high power drawings of the ampulla and isthmus.
Q 8. What is the fimbria and what is its function?
Q 9. What part of the oviduct is the ampulla?
Q10. What part of the oviduct is the isthmus?
Q11. What are the structural differences (if any) between the isthmus and ampulla?

4. 3 CORPUS LUTEUM SLIDE 176 or 196 UTERUS SLIDE 179 and SLIDE 180
Examine these sections and make high power drawings of : a). luteal cells
b). granulosa and theca cells.
Luteal cells
Granulosa and theca cells
UTERUS
SLIDE 179 and SLIDE 180
Examine under low power and make drawings of these transverse sections of uterus which show
proliferative (179) and secretory (180) stages.
Q12. What are the physiological relationships between the secretory products of the granulosa, theca
and luteal cells of the ovary and the function of the uterine epithelium?
Compare slides 179 and 180 with slide 171 (TS of anoestrus dog).
Q13. What differences can you see?

5. SLIDE 190 Cervix of ewe (TS)4
CERVIX
SLIDE 190 Cervix of ewe (TS)
Look at this section.
Make a labelled drawing of the structure at low power.
Q14. List 4 functions of the cervix 1. 2. 3. 4.
Q15. Why does the anatomy of the cervical canal differ in the :
