Premium member Presentation Transcript The Male Reproductive System: The Male Reproductive SystemMeaning and It’s Function: Meaning and It’s Function The reproductive system consists of those organs whose function are to produce mature sperm and to introduce them into the female reproductive tract where they can fertilize mature ovary.Male reproductive organs: Male reproductive organs Glands a. Testes, gonads (paired) b. Accessory glands 1. Seminal vesicles (paired) 2. Prostate gland 3. Bulbourethral (Cow’s) glands (paired)Slide 4: 2. Ducts of testes a. Epididymis (paired) b. Vas deference (seminal ducts; ducts deferens) (paired) c. Ejaculatory ducts (paired) d. Urethra 3. Supporting structures a. External- scrotum b. Internal- spermaticTestes: Testes 1. Structure and Location a. Several lobules composed of seminiferous tubules and interstitial cells (of Leydig), separated by septa, encased in fibrous capsule. b. Few ducts emerge from top of organs and enter.Slide 6: c. Located in scrotum, on testes in each of two scrotal compartments. 2. Functions a. Spermatogenesis-formation of male gamesters(spermatozoa) by seminiferous tubules. b. Secretion of hormones(testosterone) by interstitial cells. 3. Structure of spermatozoa- consist of head, neck(middle place), and whip like tail.Ducts of Testes : Ducts of Testes Epididymis 1. Structure and Location a. single tightly coiled tube enclosed in fibrous casing. b. lies along top and side of each testis. 2. Functions a. duct for seminal fluid. b. also secrets part of seminal fluid.Slide 8: c. Sperm become capable of motility while they are stored in epididymis. Vas deferens (seminal duct; ducts deferens) 1. Structure and Location a. Tube extension and epididymis. b. Extends through inguinal canal, into abdominal cavity, over top and down posterior surface and bladder to join duct from seminal vesicle.Slide 9: 2. Function a. One of excretory ducts fir seminal fluid. b. Connects epididymis with ejaculatory duct. Ejaculatory duct 1. Formed by union of vas deferens with duct from seminal vesicle. 2. Passes through prostate gland, terminating in urethra.Urethra: Urethra Accessory reproductive glands Seminal vesicles 1. structure and Location - convoluted pouches on posterior surface of bladder.Slide 11: 2. Function - secrete prostaglandins and viscous nutrient- rich part of seminal fluid . Prostate gland 1. Structure and Location a. Doughnut- shape. b. Encircles urethra just below bladder.Slide 12: 2. Function - adds alkaline secretion to seminal fluid. Bulbourethral glands 1. Structure and Location a. Small, pea- shaped structures with 1- inch long ducts leading into urethra. b. Lie below prostrate gland. 2. Function - secrete alkaline fluid that is part of semen. Supporting structures : Supporting structures External 1. Scrotum a. Skin- covered pouch suspended from perineal region. b. Divided into two compartments. c. Contains testis, epididymis, and first part of vas deferens .Slide 14: 2. Penis - composed of three cylindrical masses of erectile tissue, one which contains urethra. Internal 1. Spermatic cords a. Fibrous cylinders located in inguinal canals. 2. Enclose seminal ducts, blood vessels, lymphatic's, and nerves.Slide 15: Composition and course of seminal fluid. 1. Consists of secretions from testes, epididymides, seminal vesicles, prostate, and bulbourethral glands. 2. Each drop contains millions of sperm. 3. P asses from testes through epididymis, vas deferens, ejaculatory duct, and urethra.Slide 16: Testes Are the small ovoid glands that lie in a pouch like, skin covered structures called SCREOTUM. Ducts Of Testes Epididymis It consist of single tightly coiled tube enclosed in fibrous casing.Slide 17: Vas Deference It is a tube, and it is also a extension of the epididymis. Ejaculatory Duct Short tube that pass through the prostate gland to terminate the urethra.Slide 18: Seminal Vesicles Convoluted tube pouches that lie along the lower part of the posterior surface of the bladder. Prostate Gland Compound tubuloalveolar gland that lies just below the bladder.Slide 19: Scrotum External Skin covered pouch suspended from the perineal region. Penis 3 cylindrical masses of erectile or cavernous tissue.Slide 20: Spermatic Cords Cylindrical casing of white fibrous tissue located in the inguinal canals between the scrotum.Male Function In Reproduction: Male Function In Reproduction Male function in the reproduction consist of the production of male sex cells (Spermatogenesis). Erection is a parasympathetic reflex initiated mainly by certain tactical, visual, and mental stimuli .Slide 22: Prepared by: Camille Gem M.
