Study Notes

Internal Structure

  • The uterus is divided into body, fundus, and endometrial cavity, cervix.
  • There are two fallopian tubes, one on each side of the uterus.
  • The fallopian tubes connect each ovary with the uterine body.
  • The fallopian tube is ciliated to transport the ovum.
  • The middle section of the fallopian tube is the isthmus.
  • The funnel shaped infundibulum has finger like projections.
  • The fallopian tube ends at the ovary in funnel shape.

Vagina

  • The vagina is a muscular, membranous tube that connects the external genitalia with the cervix (birth canal).
  • It provides a passageway for sperm when attempting conception, menstrual flow during menstruation, and the fetus during childbirth.

Uterus

  • The uterus is a hollow muscular organ.
  • Its major function is protecting and nourishing the fetus until birth.
  • The fertilized ovum becomes embedded and develops into a fetus.

Ovaries

  • The ovaries are almond-sized, paired organs that lie in the pelvic cavity.
  • They are on either side of the uterus, just below the opening of the fallopian tubes.
  • They are endocrine glands that secrete estrogen and progesterone.
  • The ovaries produce the eggs.
  • The ovaries produce eggs up until menopause, except during pregnancy, a mature follicle and ovum release occur each menstrual cycle.
