Midsacittal

The ovaries produce the oocytes that are released into the pelvic cavity. Locate the suspensory ligaments that attach the ovaries to the pelvic wall. The round ligament attaches the uterus anteriorly. The oocytes travel into the uterine tubes and then pass into the uterus. The uterus has a domed fundus near the entrance of the uterine tubes and a cervix that inserts into the vagina. The depression between the uterus and the rectum is the rectouterine pouch. The vagina is inferior to the uterus and terminates with the vaginal orifice. Anterior to the vaginal orifice is the urethral orifice, the external opening of the urethra. In this section you can see the fornix of the vagina, a pocket that surrounds the cervix of the uterus. You can also see the relationship of the labium minus and the labium majus in this section. The labia minora are the inner vaginal lips and the labia majora are the outer vaginal lips. These are part of the vulva or external genitalia. Another part of the vulva is the clitoris which consists of the external glans and the body of the clitoris. The body of the clitoris is imbedded in the body tissue. The glans is covered with a prepuce. Anterior to the clitoris is the mons pubis, a fatty pad of tissue overlying the symphysis pubis. Label the organs and other structures in the midsagittal section of the female pelvis and color the structures in using different colors for each structure or space.

OVARY

The ovary is the gonad of the female reproductive system. The background tissue of the ovary is called the stroma. It produces oocytes in a process known as oogenesis and when they are mature they are released from the ovary by ovulation. The ovary has primordial follicles that contain primary oocytes. When the primary oocytes get a little larger they are located in primary follicles. As the ovulatory cycle progresses some of these primary oocytes develop into secondary oocytes. These are enclosed in secondary follicles. Usually only one of these oocytes enlarges and is ovulated.

There are two cycles that occur in the female reproductive system and they are interrelated. The ovarian cycle involves the maturation of the oocytes, ovulation, and the development of the corpus luteum. This cycle can be divided into the preovulatory phase, ovulation, and the postovulatory phase. The menstrual cycle involves the changes in the endometrium. The endometrium has a basal layer that stays the same thickness during the menstrual cycle and a functional layer that grows larger in the early part of the menstrual cycle, becomes rich in glycogen during the middle of a woman's cycle, and then is shed during menstruation.

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
