Study Notes
Male Reproductive System
- Sperm pathway: seminiferous tubules > ductus deferens > epididymis > rete testis.
- Penis: organ delivering semen to the female reproductive tract.
- Testosterone production occurs in the testes.
- Ductus deferens: passageway from the epididymis to the ejaculatory duct.
- Urethra conveys both sperm and urine through the penis.
- Bulbourethral gland contributes to semen formation and produces lubricating mucus.
- Scrotum: external skin sac that houses the testes, providing ideal temperature conditions.
- Epididymis: tubular storage site for sperm, located against the lateral aspect of the testes.
- Prepuce: cuff of skin encircling the glans penis, removed during circumcision.
- Prostate surrounds the urethra at the bladder base and produces a milky fluid.
- Seminal vesicles produce over half of the seminal fluid, containing sugar to nourish sperm.
- Spermatic cord: connective tissue sheath enclosing the ductus deferens, blood vessels, and nerves.
- The penis consists of spongy tissue that engorges with blood during erection.
- Ductus deferens structure is cut or cauterized during a vasectomy.
Female Reproductive System
- Uterus: chamber housing a developing fetus; usual site of fertilization.
- Vagina: canal receiving the penis during sexual intercourse.
- Ovary: primary female reproductive organ producing hormones and gametes.
- Uterine tube: duct through which the ovum travels to the uterus.
- Fimbrae create fluid currents to draw the ovulated egg into the uterine tube.
- Hymen partially closes the vaginal canal; lining of the uterus is the endometrium.
- Myometrium: muscular layer of the uterus aiding in contractions.
- Fallopian tubes: pathway for an egg from release to implantation.
- Round ligament helps anchor the uterus in place.
- Labia majoris is the homologous structure to the male scrotum.
Key Terms
- Scrotum: essential for temperature regulation of testes.
- Prepuce: anatomical structure involved in circumcision procedures.
- Bulbourethral gland: important for urethral cleansing and lubrication.
- Seminal vesicles: significant contributors to the volume and nutrient composition of semen.
