MALE ORGANS OF GENERATION. 



693. The male organs of generation are the Testicles, Spermatic 

 Cord, the accessory glands and ducts, the Penis containing the 

 Urethra, the Inguinal Canals, the Scrotum and the Sheath. 



694. The Testicles (Plate XVIII., M., M.J are two oval bodies 

 situated in the scrotum and attached by the upper border to the 

 spermatic cord. The testicles are the organs which secrete the seminal 

 fluid containing the spermatozoa. This fluid is carried by one of the 

 accessory organs or excretor}^ ducts — the Vas Deferens — to the 

 reservoirs near the neck of the bladder where it accumulates. 



695. The Spermatic Cords are two in number atid are made up 

 of various tissues including blood-vessels, nerves, muscular fibre, and 

 the Vas Deferens or seminal duct. These cords pass up the inguinal 

 canal and hold the testes in position in the scrotum. 



696. The Accessory Organs are the Epididymis, Vas Deferens, 

 Vesicul(Z Seminalis, the Ejaculatory Ducts, the Prostate and Cowpers Glands. 



697. The Penis fPlate XVIII., 0.), or external organ, consists 

 principally of erectile tissue, and through it runs the urethra. 



698. The Urethra (Plate XVIII., P. and Plate XXXVIII., A . 5.) is a 

 canal or passage which runs from the neck of the bladder to the anterior 

 end of the penis. The urine passes through it, and it also acts as a passage 

 for the transmission of the seminal fluid during the act of copulation. 



699. The Inguinal Canals are the short passages between the 

 abdominal cavity and the scrotum, and through them the Vas 

 Deferens, blood vessels, and nerves pass. 



700. The Scrotum is the purse or sac which holds the testes, and 

 is placed between the thighs and is made up of a series of layers of 

 integument. 



701. The Sheath is situated in front of the scrotum and is a loose 

 fold of skin investing the front and free portion of the penis, and 

 having its anterior end open.
