Study Notes
Reproductive System Overview
- The reproductive systems in both males and females contain primary and secondary sex organs and glands.
- The primary function is perpetuating the species through sexual or germ cell fertilization and reproduction.
Female Reproductive System: Uterus
- The uterus is a hollow, muscular, pear-shaped organ, roughly the size of a clenched fist.
- It normally has an anteflexion (tilted forward) position.
- It can be divided into the body (corpus) and the cervix (lower portion).
- The fundus is the rounded top portion above the fallopian tubes.
- The uterus is supported by ligaments. Trauma, disease, or multiple pregnancies can weaken these ligaments, potentially resulting in abnormal positioning.
- The uterus wall has three layers: perimetrium (outer layer), myometrium (muscular middle layer), and endometrium (inner mucous membrane lining).
- The cervical opening is about the size of a pencil.
- Functions:
- The endometrium sheds every 21-40 days through menstruation.
- Provides protection and nourishment for the fetus during pregnancy.
- Contracts during labor to expel the fetus.
Female Reproductive System: Fallopian Tubes
- A tube that widens to form the ampulla and is connected to the uterus.
- The fallopian tube ends in the infundibulum (funnel-shaped end) with finger-like projections (fimbriae). These structures capture the egg released by the ovary and transport it to the uterus.
- The egg takes 3-4 days to travel through the tube.
- Fertilization typically occurs within the fallopian tube.
Female Reproductive System: Ovaries
- Paired organs located on either side of the uterus.
- Oval-shaped and approximately the size of a large olive.
- Filled with follicles containing immature eggs (ova).
- Every 21 days, a follicle matures (graafian follicle).
- Rupture of the follicle releases the egg, a process known as ovulation.
- After ovulation, the ruptured follicle transforms into the corpus luteum, a temporary structure that secretes progesterone.
Female Reproductive System: Vagina
- Extends from the cervix to the outside of the body.
- A muscular tube approximately 3.5 inches long that expands in length and width during arousal.
- The vagina receives the semen during sexual intercourse and serves as the birth canal during childbirth
- Is a passageway for menstruation.
Female Reproductive System: Vulva
- Composed of several structures: mons pubis, labia majora, labia minora, vestibule, and clitoris.
- The perineum is the area between the vaginal opening and the anus.
- It is a muscular sheet susceptible to tearing during childbirth.
Female Reproductive System: Breasts
- Mammary glands varying in size based on age, heredity, and fat tissue.
- Each breast contains 15-20 glandular lobes separated by connective tissue.
- After childbirth, the pituitary gland stimulates the lobules with prolactin, leading to milk production.
- The areola is the dark-colored circle around the nipple, contains sebaceous glands (oil-producing).
- The first secretion is called colostrum, containing nutrients and antibodies to protect the baby.
Female Reproductive System: Menstrual Cycle
- Cycle begins at puberty and ceases at menopause.
- Consists of three phases: follicular phase, ovulatory phase, and luteal phase
Female Reproductive System: Pregnancy
- Fertilization of an egg by a sperm forms the zygote.
- The developing embryo implants in the uterus, with progesterone production increasing.
- The embryo is suspended in an amniotic sac.
- The umbilical cord connects the embryo to the placenta, providing nutrients and oxygen.
- From week 2 to 8 the developing embryo is called an embryo.
- Pregnancy is 280 days (approximately 40 weeks or 9 months).
- Labor involves muscle contractions, cervix dilation and effacement, expulsion of the mucous plug and expulsion of the fetus.
Male Reproductive System: Scrotum
- A pouch of skin containing the testicles and epididymis, where temperature is regulated.
- Scrotal tissue contracts/relaxes to maintain optimal temperature for sperm production.
Male Reproductive System: Penis
- The urethra runs through the penis, from the bladder to the meatus..
- The penis fills with blood during arousal, creating an erection for copulation.
- The foreskin (prepuce) covers the glans, and may be removed.
- A lubricant called smegma is produced underneath the foreskin.
Male Reproductive System: Testes and Epididymis
- The testes are oval-shaped organs located in the scrotum.
- They contain seminiferous tubules, where sperm are formed.
- Formed sperm are stored in the epididymis, a long coiled tube on the side of each testicle.
Male Reproductive System: Sperm
- Sperm contain genetic material (in the head), providing energy (in the mid piece). and a tail/flagellum (to propel the sperm).
- Sperm carry either an X or Y chromosome.
- X chromosome from the male or female does not affect pregnancy or the offspring's sex.
Male Reproductive System: Vas Deferens and Seminal Vesicles
- Vas deferens are muscular tubes carrying sperm from the epididymis to the seminal vesicles.
- Seminal vesicles produce an alkaline fluid, which mixes with sperm to form semen.
- Semen protects sperm from acidity in the urethra.
Male Reproductive System: Prostate and Cowper's Glands
- The prostate gland secretes an alkaline fluid that mixes with sperm in semen.
- Enlargement of prostate (benign prostatic hyperplasia) can obstruct urine flow.
- Cowper's (bulbourethral) glands produce a mucous-alkaline secretion that is released prior to ejaculation.
