Male Reproductive System Flashcards
What is the name of the canal that the testis passes through during development
Inguinal canal
What are the deep and superficial openings of the inguinal canal called
Superficial and deep inguinal ring
The inguinal canal carries a group of structures known as the
Spermatic cord
What are the main contents of the spermatic cord
Vas deferens
Testicular, cremasteric and Vas deferens artery
Lymphatics
Ilioguinal nerve, genital branch of the genitofemoral nerve and Sympathetic nerves of testicular plexus
Tunica Vaginalis
What is the tough outer fibrous layer of the testis called
Tunica Albuginea
What are the 2 layers of tunica vaginalis
Parietal and Visceral
What material is present between the 2 layers of tunica vaginalis
1-2ml of serous fluid
What is Hydrocele
Abnormal collection of fluid between visceral and parietal layers of tunica vaginalis
What is Haematocele
Collection of blood in the cavity of the tunica vaginalis
At what vertebral level do the testicular arteries arise from the abdominal aorta
L2
What 2 structures does the testicular artery cross
Psoas major
Ureter
What is the term used for the 8-12 anastomosing veins associated with the testis
Pampiniform venous plexus
What is the function of the Pampiniform venous plexus
Thermoregulatory system of the testis
Into which vein does the right and left testicular vein drain into?
Right- IVC
Left- Renal vein
What is Varicocele
Pampiniform plexus of veins become varicose (dilated) and tortuous
What is the cause of Varicocele
Defective valves of the testicular vein
Which 2 lymph node groups receive lymph from the testis
Right and left lumbar
Pre-aortic
What is the lymph drainage of the prostate
Internal iliac and sacral nodes
What is the lymph drainage of the seminal vesicle
Internal and external iliac nodes
What is the lymph drainage of the scrotum
Superficial inguinal nodes
What is the lymph drainage of the penis
Superficial inguinal nodes and internal iliac nodes
What is stored in the epididymis
Sperm
What secretion does the seminal vesicles produce
Semen
Why might an enlarged prostate gland cause retention of urine
Applies pressure on urethra
What is the clinical significance of drainage from the prostatic venous plexus
The prostatic venous plexus drains into the internal iliac vein which connects with the vertebral venous plexus, this is thought to be the route of bone metastasis of prostate cancer
What secretion is produced by the bulbourethral glands
Mucus-like secretion enters the urethra during sexual arousal
