Learning outcomes Define the structures of the male reproductive system Describe and identify the structures of the male reproductive system Define the structures of the female reproductive system Describe and identify the structures of the female reproductive system Genital (reproductive) system Male and female Reproductive cells from testes and ovaries Structures within pelvis or perineum femal male e Female reproductive system uterine tube uter us ovar y vagin a Ovaries Uterine (fallopian) tubes Uterus Vagina Ovaries and uterine tubes uterine tube fimbriae ovar y Ovaries release one ovum each menstrual cycle (alternating approx left and right) Ovum passes into uterine tube and towards uterus Fertilisation usually occurs in the uterine tube Implantation occurs in the uterus Possibility of ectopic pregnancy – uterine tube or peritoneal cavity Uterus Epimetrium, myometrium fundus and endometrium Endometrial lining for implantation or shed during BOD menstrual cycle Y Covered in peritoneum – the broad ligament cervix Support from ligaments attached to the cervix broad ligame nt Uterus –relationship to other pelvic viscera recto-uterine pouch bladder u te s ru m rectu uterus vesico-uterine bladde pouch r rectum viewed from above hemi- section Vagina Muscular tube Ability to stretch Passes through the pelvic floor (urogenital diaphragm) and into perineum Opening surrounded by erectile tissue vagina dye in peritoneal cavity hysterosalpingogr Male reproductive system Testes Vas deferens Seminal vesicles Prostate gland Penis penis prostate gland testes Testes and vas deferens Testes develop in abdominal vas cavity – too warm for deferen spermatogenesis s Descend through inguinal canal and into scrotum Vas deferens (ductus deferens) is a small muscular tube Vas deferens carries sperm from the testis to the testi epididymi ejaculatory duct in the s prostate gland s Seminal vesicles and prostate gland Seminal vesicles and prostate gland release fluid to support the sperm For example – fluid from the bladd seminal vesicles contains er fructose (energy source) prostate Vas deferens joins the duct of the seminal vesicle to form the ejaculatory duct (one each side) seminal Ejaculatory duct joins with the vesicle prostatic urethra Male urethra Unites reproductive and urinary systems tum bladd semin er bladder rec al vesicl e penile prosta ejaculatory te duct urethra Penis Carries sperm into female urethra genital tract Erectile tissue – spongy structure fills with blood Penile or spongy urethra erectile tissue bladder semina l rectu vesicle m https://upload.wikimedia.org/wikipedia/commons/2/27/ © Nevit Dilmen [CC BY-SA 3.0 Pelvic_MRI_T1FSE_T2frFSE_T2FSfrFSE_11.jpg (http://creativecommons.org/licenses/by-sa/3.0) or GFDL (http://www.gnu.org/copyleft/fdl.html)], via Wikimedia
