Document Summary
Secondary sex characteristics: physical characteristics other than genitals that distinguish males from others, mammary glands: produce milk, areola: darker area, nipple: located in the center of the areola and has openings for milk. Important considerations: breast self-examination, breast cancer screening: mammography, breast lumps: cysts, fibro-adenomas (solid, round, benign tumors), and malignant tumors, breast caner: treatments, risk factors, reconstructive breast surgery, early detection. Female genital structures include both external and internal underlying structures and organs. Female bodily processes include menstruation and menopause (cessation of menstruation) External anatomy of the penis: foreskin, glans, shaft and root. Internal anatomy of the penis: cavernous bodies consists or (corpis cavernosa), spongy body (corpus spongiosum), and penile urethra, engorge with blood during arousal. Areas particularly responsive to stimulation: corona: rim of penile glans, frenulum: highly sensitive thin strip that connects glans to shaft. Stretching musculature around penis: kegel exercises can produce benefits (same approach as women)
