Week 10: Anatomy of the Male Reproductive system Flashcards
What is homologues feature to scrotum in females
labia majora
What is homologues feature to spongy urethra in females
labia minora
What is homologues feature to bulbourethral glands in females
greater vestibular gland
Male external genitalia
scrotum, testes, epidymus, spermatic cord, penis, secretory glands
Male internal genitalia
Vas deferens, seminal vesicle, prostate gland
Scrotum features
Contains no fat - dartos fascia - continuous with abdominal fascia, contains smooth Dartos msucle
What divides scrotum compartments
scrotal septum/raphe of dartos fascia
External features of testis
Surrounded by tunica vaginalis (parietal and visceral)
What does parietal layer of tunica vaginalis adhere to?
Internal spermatic fascia
What separates lobules of seminiferous tubules?
Tunica albuginea
What vessels to sperm exit testis via?
Efferent ductules
What surface of testis is epidymus?
Posterolateral
Boundary between lateral testis and lateral epididymus is called?
Sinus of epididymus
What is in the spermatic cord?
vas deferens, testicular artery, pampiniform venous plexus, nerves and lymphatics
What are the layers of fascia that wrap the spermatic cord? Ext to int
External spermatic fascia (beneath dartos fascia), cremasteric fascia (skeletal muscle, reflex raises), Internal spermatic fascia
T or F: The cremaster muslce is smooth, involuntary muscle that raises the testis - reflex
f: Skeletal muscle!
After passing through the inguinal canal, the contents of spermatic cord separate:
Vas deferens - pelvis
Nerves/lymphatics - abdomen
Pampiniform - abdomen
Testicular artery - originates in abdomen
What do the pampiniform veins anastomose to form?
Testicular veins
Where do testicular veins drain?
Left - renal vein
Right - IVC
Penis - 3 main parts
Root (bulb, crura), Body (corpus spongisum, cavernosum), glans
Layers of fasca in penis
Superficial dartos fascia, deep buck’s fascia
Blood supply penis
pudendal, internal iliac
Bulbourethral glands location, secrete into
Pelvic diaphragm, drain into spongy at bulb of penis
___ and ___ open onto the ____ on the posterior wall of the porstatic urethra.
Ejaculatory ducts, utricle, seminal colliculus
Anatomical homologue to vagina and cervis
utricle
