Female Genitals: Internal Organs: - The Vagina : A canal that starts at the vaginal opening and extends up and tilts slightly backwards toward the base of the spine. - The Bartholin Glands : small pair of glands that lie to the right and left of the vagina. There function is widely unknown but they may contribute to vaginal lubrication just before orgasm. Vestibular Bulbs of the clitoris have erectile tissue similar to the spongy bodies of the penis. o Bartolinitis - The Skene’s Glands: This pair of glands are on the front wall of the vagina and their ducts empty into the urethra. The may be the “female prostate” and part of the G-spot. - The G-Spot: The Grafenberg spot: a large area located on the front vaginal wall. Extremely pleasurable for some women and for others not. Some females ejaculate a fluid very similar to male prostate fluid from their urethras. - The Ovaries: Two ovaries at the end of the fallopian tubes on each side of the uterus. They are endocrine glands that produce both estrogen and progestin’s. Usually a woman ovulates an ova (egg) alternately from one ovary then the other. Responsible for relasing ovum and female hormones. o each ovary lives inside a fibre sac which contains a layer of connective tissue ( tunica albuginea ) and another layer of cuboidal epithelial cells called the germinal epithelium . The ovary contains a cortex which houses the developing eggs and a medulla which contains most of the ovary’s blood vessels and nerves. o The ovarian follicles in the cortex are tiny sac-like structures that each hold a primary oocyte (incomplete egg) with supporting follicles around it - The Cervix: located at the top of the vagina. Secretes mucous through its glands. OS is the opening at the centre of the cervix. - Uterus: innermost layer is the endometrium (shed during menstruation). Second layer is the myometrium (muscular). Third layer is the perimetrium (smooth outer layer). Cancer of the Cervix: - Third most common form of cancer in women - Cause: most by human papilloma virus. - Is curable - Pap test- highly accurate test - Hysterectomy sometimes used as a treatment. - HPV- solution Gardasil shot. The vaccine could only be free if you are female. Most effective before your sexual debut!!! - Most women have received the vaccine but most men have not.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
