What are the main contents of the spermatic cord?
Testicular artery
Genital branch of genitofemoral nerve
Vas deferens
What is the name of the tough outer fibrous layer of the testis?
Tunica albuginea
What forms the tunica vaginalis?
Parietal and visceral peritoneum
Between what layers does a hydrocele form?
Parietal and visceral tunica vaginalis
What is a haematocele?
Blood collecting inbetween layers of tunica vaginalis
What is the blood supply to the testis?
Testicular artery
At what vertebral level does the testicular artery arise from the abdominal aorta?
L2
What 2 structures do the testicular arteries cross at the pelvic brim?
Common iliac vein
Common iliac artery
What is the name given to the bundle of veins shown here?
Pampiniform plexus
What are the two functions of the pampiniform plexus?
Venous return
Temperature regulation
Into which vein does the right testicular vein drain?
IVC
Into which vein does the left testicular vein drain?
Left renal vein
What is shown here and what usually causes it?
Varicocele
- Dilated tortuous veins of the pampiniform plexus
- Renal vein stenosis or other that increases pressure
What are the two lymph node groups that recieve lymph from the testis?
Inguinal
Paraaortic
Identify the inguinal and paraaortic lymph nodes
- Paraaortic
- Common iliac
- Internal iliac
- Inguinal
What is the course of the vas deferens?
Arises at the tail of the epididymis
Traverses the inguinal canal
Enters the pelvis by crossing the external iliac vessels
Terminates by joining the duct of the seminal gland
What type of tube is the vas deferens?
Muscular
What is the name given to the tube formed by the joining of the seminal duct and the vas deferens?
Ejaculatory duct
What point of the urethra does the ejaculatory duct join?
Prostatic urethra
What is shown here by “5”
Seminal vesicles
What is the main constituent of the secretions of the seminal vesicle?
Fructose for energy
What are the main secretions produced by the prostate and what is the function?
Alkaline
Neutralise acidity of female tract
What is the drainage of the prostate via?
Prostatic venous plexus
What is the clinical significance of the prostatic venous plexus?
It connects to the vertebral venous plexus and is a route of metastasis
Summary of male venous drainage
What is shown here?
Bulbourethral gland
Where do the bulbourethral glands enter the urethra?
Spongy urethra
What are the main secretions of the bulbourethral gland?
Mucoproteins for lubrication of the urethra
What is the lymphatic drainage of the prostate?
External iliac
Sacral
What is the lymphatic drainage of the seminal vesicle?
Internal iliac
What is the lymphatic drainage of the scrotum?
Superficial inguinal
What is the lymphatic drainage of the penis?
Glans: Deep inguinal and external iliac
Skin: Superficial inguinal
