1. PHYSIOLOGY
REPRODUCTION

6. Oogenesis: Egg Cell Formation
Oogonia mitosis ceases before birth
At birth: only primary oocytes – suspended in prophase of meiosis I (= prophase I)

7. Oogenesis after Birth:
At puberty: ↑ estrogen initiates ovarian cycle
ovulation
2nd meiotic division completed after fertilization

15. Growth and Aging Puberty (  GnRH) Menopause Andropause
in girls = menarche
Average 12 y
In boys, later (harder to pinpoint a time)
Menopause
Irregular menstrual periods and cessation
Andropause
Similar drop in androgens

17. The ampulla, fimbriae, and infundibulum are anatomical features of the
Uterus
Cervix
Vagina
Fallopian tubes

18. Spermatogenesis Seminiferous tubules
Sertoli cells: androgen binding protein blood testes barrier etc.
Leydig cells testosterone vs. DHT

19. On average the process of ovulation occurs every
2-3 days
14-15 days
28-30 days
8-9 months

20. Development of the embryo takes place in the tissue layer of the uterus known as the
Perimetrium
Endometrium
Myometrium
Neurometrium

21. The corpus luteum forms from the
Residual cells of the follicle
Ectoderm and endoderm cells
Ciliated cells of the Fallopian tube
Greater vestibular gland

22. During days 15-28 of the menstrual cycle
The level of progesterone is lowest
The uterine lining is removed from the body
Ovulation takes place
The corpus luteum secretes progesterone
The corpus luteum secretes estrogen

27. `

28. Biosynthetic Pathway for Steroid Hormones
Theca cells
Synthesize androgens
Granulosa cells
convert androgens to
estrogen
diffusion

34. The epithelium cells that produce sperm cells are located in the testes within the
Seminiferous tubules
Vas deferens
Corpus spongiosum
Ampulla
Prostate Gland

35. The chromosomes of a sperm cell are contained
Within the flagellum
Packed in the head of the cell
Within the acrosome of the cell
In the neck of the sperm cell

36. Secretions of the seminal vesicle
Are alkaline
Pass into the testes
Are acidic
Contain sperm cells

37. The general term given to male sex hormones is
Estrogen
Thymosins
Androgens
Prostaglandins
Testosterones

38. Which of the following hormones controls the release of anterior pituitary gonadotropins?LH
GnRH
FSH
Testosterone
CRH
