Study Notes
Overview of the Female Reproductive System
- The female reproductive system includes internal and external genitalia.
- Internal genitalia includes the ovaries, uterine tubes, uterus, and vagina.
- External genitalia includes the vulva/pudendum.
- The female reproductive system produces sex hormones and functional gametes, protects and supports the developing embryo, and nourishes the newborn infant.
The Uterus, Uterine Tubes, and Vagina
- The uterus is a thick-walled muscular organ responsible for developing the embryo and fetus.
- The cervix is the lower opening of the uterus that opens into the vagina.
- The uterus is supported best at the cervix.
- Uterine tubes project laterally from the uterus and open near the ovaries.
- The vagina is a thick-walled muscular tube that serves as a passage for menses, birth canal, and receives the penis and ejaculate during intercourse.
Layers of the Uterus Body
- The uterus is composed of three layers: perimetrium, myometrium, and endometrium.
- The endometrium is the inner lining of the uterine wall that supports pregnancy.
- The endometrium is actively involved in the menstrual cycle and is shed if conception does not occur.
- The endometrium is highly vascular, which is required for implantation.
The Uterine Tube
- The uterine tube is comprised of four parts: the uterine part, the isthmus, the ampulla, and the infundibulum.
- The uterine tubes open into the peritoneum posteriorly and project laterally from the uterus.
- The fimbriated infundibulum facilitates the collection of oocytes.
The Ovaries
- The ovaries are located adjacent to the lateral wall of the pelvis.
- The ovaries are attached to the uterus by ligaments.
- The ovaries release an oocyte during each menstrual cycle between puberty and menopause.
Fertilization and Implantation
- Fertilization occurs when sperm meets egg in the uterine tube.
- Implantation occurs when the fertilized egg attaches to the uterine wall.
The Ovarian Cycle
- The ovarian cycle is a monthly process that involves the maturation, ovulation, and degeneration of tertiary ovarian follicles.
- The ovarian cycle is divided into two phases: the follicular phase and the luteal phase.
The Uterine Cycle
- The uterine cycle involves the degeneration and shedding of the functional endometrium (menstrual phase), the rapid growth of new endometrial tissue (proliferative phase), and the secretion of uterine glands (secretory phase).
The Ovarian and Uterine Cycle Relationship
- The menstrual and proliferative phases of the uterine cycle occur during the follicular phase of the ovarian cycle.
- The secretory phase of the uterine cycle occurs during the luteal phase (postovulation) of the ovarian cycle.
Female External Genitalia
- The female external genitalia is referred to as the vulva/pudendum.
- The labia minora are two thin folds of skin located on either side of the midline.
- The vestibule is the area between the labia minora and contains the opening for the urethra and vagina.
- The labia majora are larger folds of skin that are located over the vestibule and lateral to the labia minora.
The Penis
- The penis is comprised of the body, the root, and the glans penis.
- The urethra opens at the glans penis.
- The pelvic structures form the attachment for the roots of the external genitalia.
- Erection is mediated by the parasympathetic nervous system which relaxes the arteries in the penis, allowing blood to fill the erectile tissues.
Erectile Tissues
- The penis contains two corpora cavernosa and a single corpus spongiosum which are erectile tissues.
- The urethra enters the corpus spongiosum.
