Study Notes

The Biological Female

Anatomy involves studying structures relating to the body's parts; female sexual anatomy is designed for ovum production, fertilization, and infant delivery.
Puberty brings the final development of primary and accessory reproductive organs.
External Genitalia Components include:
- Vulva: all external genital structures combined.
- Mons Veneris: fatty tissue pad located between the pubic bone and skin.
- Labia Majora: outer lips encasing other structures.
- Clitoral Hood (Prepuce): skin covering the clitoris.
- Clitoris: sensitive organ with a glans, shaft, and root; sensitive to stimulation.
- Labia Minora: inner lips surrounding the vestibule with blood vessels and nerve endings.
- Vestibule: area around the urethral opening and vagina; highly sensitive.
- Urethral Opening: connects to the bladder and facilitates urination.
- Vaginal Opening (Introitus): entry to the vagina.
- Perineum: skin area separating genitalia from anus; shorter distance in females than in males.
Internal Structures:
- Vagina: collapsible canal from the opening to the cervix, engorges with blood during arousal, releasing lubricants.
- Cervix: the narrow end of the uterus leading to the vagina.
- Uterus: organ in the pelvic area for carrying a fetus.
- Fallopian Tubes: channels for transporting egg cells from ovaries to the uterus; site of fertilization.
- Ovaries: produce estrogen and progesterone; responsible for ovum production and maturation, with approximately 400,000 ova surviving to puberty.

Menstrual Cycle and Puberty

Menarche: first menstrual episode occurs between ages 11-15.
Menstruation: sloughing off of the uterine lining if no conception occurs, lasting 2-6 days, with cycles spanning 24-42 days.
Ovulation: occurs approximately 14 days before the next menstrual cycle.
Regulation: hypothalamus monitors hormone levels influencing the cycle.
Secondary Sexual Characteristics post-puberty include:
- Widening hips and pelvis for birthing.
- Breast enlargement due to developing glandular and fatty tissues.
- Height generally shorter than males and higher body fat percentage.
- Two X chromosomes reduce the expression of sex-linked conditions.
- Longer projected lifespan and lower mortality rates compared to males.

The Biological Male

Male anatomy facilitates sperm production and delivery for fertilization of the female ovum.
External Genitalia Components include:
- Prepuce: foreskin removed during circumcision.
- Penis: consists of glans (head), shaft, and root; sensitive to stimulation.
- Urethra: runs through the penis, surrounded by spongy body and cavernous bodies, engorging with blood during arousal, leading to erection.
- Corona: rim of the glans where it joins the shaft.
- Frenulum: skin strip connecting glans and shaft.
- Scrotum: sac containing compartments for testes.
- Urethral Opening: located at the penis head, serving as the passage for urine and sperm.
