Female Reproductive System Flashcards
Labia majora
Large folds of fibrous tissue and fat covered in skin, containing sebaceous and sweat glands
Labia minora
Smaller folds of skin (between labia majora) containing sebaceous and sweat glands
Clitoris
Corresponds to the penis; contains sensory nerve endings and erectile tissue
Vestibular glands (bartholins)
Pea-sized glands situated on each side near vaginal opening- secrete mucus to keep vulva moist
Perineum
Triangular area extending from base of labia minora to the anal canal – consists of connective tissue, muscle and fat
Gives attachment of the muscles to the pelvic floor
Vagina
Fibromuscular 7.5-9cm long tube lined with epithelium Surface kept moist by cervical secretions; bacterium maintains pH between 4.9 and 3.5; acidity prohibits micro organism growth.
Uterine (fallopian) tubes
Approx. 10 cm long extending from sides of uterus.
Smooth muscle middle layer and lined with ciliated epithelium.
After ovulation the ovum is propelled to uterus by cilia action and peristalsis. Fertilisation occurs in the tube.
Ovaries
Female gonads attached to upper part of uterus
2 layers of tissue, and contains follicles.
Females have primordial (immature) follicles from birth
How is milk produced in the breast?
Milk production is stimulated by prolactin from the anterior pituitary, esstrogens, and progesterone
Milk production (continued)
Oxytocin, from the posterior pituitary, stimulates milk release in response to stimulation of the nipple via suckling (positive feedback mechanism)
Tumours
Benign breast tumours (90%)
•Fibroadenomas – most common; occur anytime after puberty, peaking in the 3rd decade
•Other tumours may be cystic or solid; usually around the menopause

Breast cancer risk factors
Most common cancer worldwide in women; incidence increasing
•Risk factors
•increasing age (up to 70yrs), alcohol consumption, obesity, early menarche, late menopause, no pregnancies because they have more oestrogen surges in menstrual cycles
•Genetic element – familial link; 5-10% linked to BRCA1 and BRCA2 (80-90% chance of developing cancer, including ovarian and bowel cancer)
