Document Summary
Reproductive system: responsible for producing offspring, composed of primary sex organs (ovaries/testes) that produce gametes and secrete sex hormones, and accessory sex organs which include various glands and ducts. Cremaster muscle: contraction brings the testes closer to the body. Dartos muscle: smooth muscle, contraction wrinkles scrotal skin and. Scrotum: external out pocketing of the abodominopelvic wall that houses the testes, external location is required lower temperature for sperm production makes dissipation of heat more difficult. Testes: paired oval glands located in the scrotum (retroperitoneal), produces sperm and hormones. Tunica albuginea: dense fibrous connective tissue that divides the testes into lobules. Duct system: sperm leaving the seminiferous tubules travels through the male reproductive tract. Urethra: prostatic urethra (in prostate), membranous urethra (in urogenital diaphragm), spongy urethra (in penis) Seminiferous tubules -> epididymis -> vas deferens -> ejaculatory duct -> urethra. Seminical vesicle: elongated, paired glands, posterior to the bladder. Prostate: single, chestnut shaped gland at the base of the bladder.
