Study Notes
Reproductive System Anatomy
- The testis consists of seminiferous tubules and interstitial tissue surrounded by a thick connective tissue capsule, the tunica albuginea.
- The epididymis is a single, long coiled duct that functions in the maturation of spermatozoa.
- The spermatic cord is the tube-shaped connection between the scrotum and the abdominal wall, containing the ductus deferens, testicular artery, and pampiniform plexus of veins.
- The ductus deferens is a long muscular duct that transports spermatozoa from the epididymis to the pelvic cavity.
- The ejaculatory duct is a short passageway that penetrates the muscular wall of the prostate gland.
- The seminal vesicles contribute about 60% of the volume of semen, containing fructose and prostaglandins.
- The prostate gland produces prostatic fluid, contributing 20–30 percent of the volume of semen.
- The bulbourethral glands secrete a thick, sticky, alkaline mucus that helps neutralize urinary acids and contributes to lubrication.
- The female reproductive tract mainly consists of the ovaries, uterus, vagina, and clitoris, with accessory glands such as the greater vestibular glands.
- The perineum is a diamond-shaped region between the thighs, with the pudendal nerve and internal pudendal artery as major nerve and artery.
- The perineum is divided into an anterior urogenital triangle and a posterior anal triangle, each associated with specific functions.
- The perineum contains several muscles including the deep transverse muscle, superficial transverse muscle, ischiocavernous muscle, and bulboespongiosus muscle.
