Study Notes

Male Reproductive System

Scrotum: External pouch that contains and protects the testes.
Cremaster Muscle: Muscle controlling the position of the testes for temperature regulation.
Seminiferous Tubules: Structures within the testes where sperm production occurs.
Epididymis: Coiled tube responsible for the maturation and storage of sperm.
Ductus Deferens: Tube transporting sperm from the epididymis to the ejaculatory duct.
Ejaculatory Duct: Passes sperm mixed with seminal fluid into the urethra.
Seminal Vesicles: Glands producing a significant portion of seminal fluid, nourishing sperm.
Prostate Gland: Contributes additional fluid to semen, enhancing sperm mobility and viability.
Bulbourethral Glands: Produce a mucous secretion that lubricates the urethra.
Prostatic Urethra: The portion of the urethra that runs through the prostate gland.
Membranous Urethra: Short section of the urethra between the prostate and spongy urethra.
Spongy Urethra: The longest part of the urethra, located within the penis.
Glans Penis: The sensitive tip of the penis.
Prepuce: Also known as the foreskin, covers the glans.
Erectile Tissue: Specialized tissue that becomes engorged with blood to facilitate an erection.
Corpora Cavernosa: Two columns of erectile tissue along the length of the penis.
Corpus Spongiosum: Surrounds the spongy urethra, preventing its collapse during erection.
Inguinal Canal: Passageway through which structures enter and exit the scrotum.
Spermatic Cord: Bundle of fibers, blood vessels, and ductus deferens connecting the testes to the abdomen.

Female Reproductive System

Ovary: Female reproductive organ producing eggs and hormones.
Primary Follicle: Immature ovarian follicle; the first stage of egg development.
Graafian Follicle: Mature follicle ready for ovulation.
Follicular Cells: Cells surrounding and supporting the developing oocyte in the follicle.
Corpus Luteum: Structure formed after ovulation, producing progesterone.
Tunica Albuginea: Dense layer of connective tissue protecting the ovaries.
Round Ligament: Supports the uterus, extending from the ovaries to the labia.
Suspensory Ligament of Ovary: Attaches ovaries to the lateral pelvic wall, containing blood vessels.
Ovarian Ligament: Connects the ovaries to the uterus.
Broad Ligament: Large peritoneal fold covering the uterus, ovaries, and fallopian tubes.
Fallopian Tubes: Tubes through which eggs travel from the ovaries to the uterus.
Infundibulum: The funnel-shaped opening of the fallopian tube near the ovary.
Fimbriae: Fringe-like projections at the end of the fallopian tube helping to catch the egg.
Ampulla: The widened region of the fallopian tube where fertilization often occurs.
Uterus: Hollow organ where a fertilized egg implants and develops.
Cervix: The lower part of the uterus connecting it to the vagina.
Fundus: The top portion of the uterus.
Endometrium: Inner layer of the uterus, thickens each cycle and is shed during menstruation.
Myometrium: Middle muscular layer of the uterus, aids in contractions during labor.
Perimetrium: Outer protective layer of the uterus.
Vestibular Gland: Glands near the vaginal opening providing lubrication.
Hymen: Membrane partially covering the vaginal opening.
Fornix: Recess around the cervix in the vagina.
Mons Pubis: The fatty tissue covering the pubic bone.
Labia Minora: Inner folds of skin surrounding the vaginal opening.
Labia Majora: Outer folds of skin protecting the genitalia.
Clitoris: Highly sensitive structure involved in sexual arousal.
Urethral Opening: Opening through which urine is expelled.
Vaginal Opening: Entrance of the vagina, located at the middle.
Nipple: Structure from which milk is delivered in females.
Areola: Pigmented area surrounding the nipple.
Mammary Glands: Glands responsible for milk production in females.
Lactiferous Duct: Ducts that carry milk from mammary glands to the nipple.
