FEMALE REPRODUCTIVE ANATOMY Chapter 16
Slide 2-

EXTERNAL GENITALIA The vulva refers to those parts that are outwardly visible The vulva includes: Mons pubis Labia majora Labia minora Clitoris Urethral opening Vaginal opening Perineum Individual differences in: Size Coloration Shape

MONS PUBIS The triangular mound of fatty tissue that covers the pubic bone During adolescence sex hormones trigger the growth of pubic hair on the mons pubis
Slide 5-

LABIA MAJORA Referred to as the outer lips They have a darker pigmentation The Labia Majora: Protect urethral openings Covered with hair and sebaceous glands Tend to be smooth, moist, and hairless Become “flaccid” with age and after childbirth
Slide 6-

LABIA MINORA Referred to as the “inner lips” Made up of erectile, connective tissue that darkens and swells during sexual arousal Inside the labia majora They are more sensitive and responsive to touch than the labia majora
Slide 7-

CLITORIS Highly sensitive organ composed of nerves, blood vessels, and erectile tissue Located under the prepuce Becomes engorged with blood during sexual stimulation Key to sexual pleasure for most women Urethral opening is located directly below clitoris
Slide 8-

VAGINAL OPENING INTROITUS Opening may be covered by a thin sheath called the hymen Presence of an intact hymen helps determine virginity Some women are born without hymens The hymen can be perforated by many different events
Slide 9-

PERINEUM The muscle and tissue located between the vaginal opening and anal canal Contains an abundance of nerve endings that make it sensitive to touch An episiotomy is an incision of the perineum used during childbirth for widening the vaginal opening
Slide 10-

INTERNAL GENITALIA The internal genitalia consists of the: Vagina Cervix Uterus Fallopian Tubes Ovaries

VAGINA The vagina connects the cervix to the external genitals It is located between the bladder and rectum It functions : As a passageway for the menstrual flow For uterine secretions to pass down As the birth canal during labor With the help of two Bartholin’s glands becomes lubricated
Slide 13-

CERVIX Connects uterus to vagina The cervical opening to the vagina is small Protects from foreign bodies entering uterus During childbirth, cervix dilates to allow passage of the fetus This dilation is a sign that labor has begun

UTERUS Commonly referred to as the womb A pear shaped organ about the size of a clenched fist Consists of blood-enriched tissue that sloughs off each month during menstrual cycle The powerful muscles of the uterus expand to accommodate a growing fetus and push it through the birth canal

OVIDUCTS
Slide 18-

FALLOPIAN TUBES Pathway for the ovum to the uterus Site of fertilization by the male sperm Often referred to as the oviducts or uterine tubes Fertilized egg takes approximately 6 to 10 days to travel through the fallopian tube to implant in the uterine lining
Slide 19-

OVARIES The female gonads or sex glands Develop and expel an ovum each month A woman is born with approximately 400,000 immature eggs called follicles The follicles in the ovaries produce the female sex hormones, progesterone and estrogen These hormones prepare the uterus for implantation of the fertilized egg
Slide 20-

BREASTS Organs of sexual arousal Contain mammary glands Consist of connective tissue that serves as support Each breast contain 15-25 clusters called lobes Each lobule is connected by ducts that open into the nipples The nipples are made up of erectile tissue The pigment around the nipples is called the areola Breast size is determined primarily by heredity Size also depends on the existing fat and glandular tissue Breasts may exhibit cyclical changes, including increased swelling and tenderness prior to menstruation

MENSTRUATION Menarch, the onset of menstruation signals the bodily changes that transform a female body Average age is 12.8 Amount of bleeding varies from woman to woman Blood color can vary from bright red to dark maroon Usually occurs every 25 to 32 days Women can experience fluid retention, cramping, mood swings, weight gain, breast tenderness, diarrhea, and constipation
Slide 23-

SEX HORMONES Follicle stimulating hormone FHS- Luteinizing hormone LH-signals ovulation Estrogen- produced throughout the menstrual cycle Progesterone-produced during second half of cycle Contributes to thickening of the endometrium which is shed during menstrual phase if fertilization does not take place Both FHS and LH are produced in the pituitary gland Both estrogen and progesterone are produced by the follicles in the ovaries
Slide 24-

DYSMENORRHEA Painful menstrual cramps Painful menses without evidence of a physical abnormality Believed to be normal body response to uterine contractions Prostaglandins cause forceful, frequent uterine contractions called cramps
