- - - - process of sperm development
        
        occurs within the seminiferous tubule
        
        begins during puberty
        
        significant levels of FSH & LH secreted
      - Spermatogonia
        
        line of cells that are constantly dividing during mitosis
        
        Primodial germ cells
        
        divide by MITOSIS
        
        Spermatogonium
        
        Primary spermatocyte
        
        diploid cells undergo MEIOSIS

  - - - increases surface area to maintain temperature of testis
- - - - 3 layers
        
        Perimetrium
        
        incomplete outer most serous layer
        
        Myometrium
        
        middle layer; smooth muscle
        
        contracts rhythmically during childbirth
        
        Endometrium
        
        mucosal lining of uterine cavity
        
        simple columnar epithelial tissue
  - - - usually site of fertilization of the ovulated oocyte
  - - - occurs in stages over the life span of a female
        
        Before birth
        
        ovary contains primordial germ cells- Oogonia
        
        Diploid cells divide by MITOSIS
        
        Cells start MEIOSIS
        
        cells now primary oocytes

        Childhood
        
        ovaries are inactive with no follicles developing
        
        From puberty - menopause
        
        primary oocyte finishes MEIOSIS 1 and forms 2 cells
        
        completes meiosis if fertilized
        
        After menopause
        
        normal onset from ages 45-55
        
        no more ovarian follicles remain ; follicle maturation stops
        
        uterine lining no longer growing
        
        no further menstrual periods
      - maturation of primary oocyte to secondary oocyte
  - - - expands and contracts during childbirth
  - - - membrane enclosing the entrance to the vagina
  - - - located above urethra opening
        
        extremely sensitive to touch
    - - Majora (external)
      - Minora (internal)
- - - - condoms, spermicidal gels, diaphragms
  - - - help prevent implantation
        
        made of copper or synthetic progesterone
  - - - prevents sperm from reaching uterus
  - - - sperm unable to leave testis
- - - - Withdrawl
        
        biggest risk not timed correctly
      - Rhythm method
        
        may have irregular menstration
      - Oral contraceptives
        
        risk - may forget to take 1 or multiple days
  - - - prevents sperm from reaching uterus
    - - Sperm is unable to leave testis
- - - - Days 1-13 of Ovarian cycle
      - Primodial Follicles
        
        Primary Follicle
        
        Secondary Follicles
        
        Vesicular Follicle
        
        Primary Oocyte finishes meiosis 1 & forms 2 cells
        
        one polar body (non-functional) & other oocyte
        
        1 more item...
        
        volume of fluid increases within follicle antrum
        
        usually only 1 follicle matures into a vesicular follicle
        
        only a few follicles turn into secondary follicles
        
        stimulated to mature by LH & FSH
    - - Occurs on day 14 of ovarian cycle
      - Ejection of secondary Oocyte from mature F. into uterine tube
        
        Induced with "peak" in LH secretion; telling ovary its time for cycle
        
        Antrum increases in size and swelling
        
        expands until ovarian surface thins
        
        eventually ruptures expelling secondary oocyte
        
        Usually only one ovary ovulates each month
    - - Remaining cells become corpus lutem
        
        temporary endocrine gland
        
        secretes Progesterone and Estrogen
        
        corpus luteum regression
        
        causes drop in secreted progesterone & estrogen
        
        causes MENSTRATION- shedding of uttering lining
        
        sheds lining (MENSES)
        
        marks end of luteal phase
        
        Builds up uterine lining, preparing for fertilized oocyte
        
        lifespan of 10-13 days if not fertilized
      - Occurs on day 15-28 of ovarian cycle
  - - - days 1-5 of cycle
      - lasts through period of menstrual bleeding
      - occurs during Follicular phase of ovarian cycle
      - Shedding of functional layer of endometrium
    - - Days 6-14 of cycle
      - occurs during Follicular and Ovulation phase of ovarian cycle
      - Development of new functional layer of endometrium
      - overlaps time of follicle growth and ovary estrogen secretion
    - - Occurs during Luteal Phase of ovarian cycle
      - increased Progesterone secretion from corpus luteum
      - increases vascularization and uterine gland development
      - if fertilization does not happen
        
        degeneration of corpus luteum
        
        dramatic drop of progesterone
        
        sheds off functional layer of endometrium
      - Days 15-28 of cycle
