Anatomy workbook - 2 Flashcards
1
Q
Male reproductive system is classified into 4 categories
A
- External genitalia
- Gonads - site of gamete and male sex hormone production
- The tube system - transportation of sperm to gonads
- Accessory glands - supports sperm and lubricate copulatory organs
2
Q
Organs of the male reproductive system
A
- Testis
- Vas deferens/ ductus deferens
- Seminal vesicles
- Seminal glands
- Prostate
- Epididymis
- Bulbourethral glands
3
Q
Canal which the testis pass through during development
A
- Inguinal canal
4
Q
Main contents of the spermatic cord
A
- Testicular artery
- Cremasteric artery
- Artery to vas deferens
- Paminiform plexus (testicular vein
- Genital branch of genitofermal nerve
- Autonomic nerves
- Vas deferens
- Processus vaginalis
- Lymph nodes
5
Q
Fibrous outer layer of the testis
A
- Tunica albuginea
6
Q
Two layers of the tunica vaginalis
A
- Visceral and parietal
- 1-2ml of serous fluid between
7
Q
Two pathologies associated with tunica vaginalis
A
- Hydrocele → abnormal accumulation of fluid due to inflammation, infection, tumour etc
- Haematocele → accumulation of blood between later due to trauma to testis
8
Q
Blood supply of testis
A
- Testicular arteries
- Branch of the abdominal aorta (L2-3 level)
- Travels retroperitoneally crossing genitofemoral nerve and ureter before travelling through inguinal canal
9
Q
Venous drainage of the testis
A
- Pampiniform plexus (anastomosing veins)
- Right testicular vein → IVC
- Left testicular vein → left renal vein
10
Q
Function of pampiniform plexus
A
- Homeostatic heat exchange with testicular artery (maintains testicular temperature)
11
Q
Varicocele
A
- Abnormal enlargement of venous network of testis
- Cause
- Proximal obstruction of spermatic vein
- Retroperitoneal mass
12
Q
Testicular torsion
A
- Emergency prevention where blood supply to testis completely cut off
- Risk of necrosis within a few hours
- Requires immediate operation and internal fixation
13
Q
Lymph node groups that drains testis
A
- Para-aortic
- Sacral
14
Q
Lymphatic drainage of male reproductive organs
A
- Prostate → internal iliac and sacral
- Seminal vesicle → external iliac
- Scrotum → superficial inguinal
- Penis → superficial inguinal
15
Q
Epididymis
A
- Attached to body of testis
- Stores sperm from testis
