MALE REPRODUCTIVE SYSTEM Flashcards
parts of the urethra?
- prostatic part
- membranous part
- spongy part (longest)
endoscopic features to remember
- membranous part run (ant & inf)
- prostatic part (concave ant)
- spongy part (inf & post) covered by erectile tissue
blood supply of the penis? and where do they branch from?
- 2x dorsalis artery
- cavernous artery
- bulbourethral artery
- *** branch from the internal pudental artery
venous drainage of the penis?
- superficial dorsal vein
- deep dorsal vein (circumflex and emissary veins)
characteristics of flacid state?
- arteriole constricted
- veins open
- trabecular muscle contracted
- low pressure in corpus cavernosum
- sympathetic nervous system active
characteristics of erect state?
- arteriole are relaxed
- veins occluded
- trabecular smooth muscle relaxes
- high pressure in corpus cavernosum
- parasympathetic system active
ejaculation process
1) contraction of reproductive ducts and release of their content
2) bulbospongiosus muscle contracts fast, semen released from urethra
what is covered by the parietal peritoneum?
- seminal vesicle
- ductus deferens
- prostate
- superior surface of the urinary bladder
what creates the rectovesical pouch? and where does it extend from?
- parietal peritoneum
- post. wall of urinary bladder on to the ant. wall of the rectum
what is the retrovesicle fold?
what does it consist of?
- fold bordering the retrovesical pouch
- consist of peritoneal covering connective tissue and the inferior hypogastric nerve plexus
arteries of the male reproductive organs?
and the branches from where they come from?
- testicular a. (abdominal aorta)
- cremasteric a. (inferior epigastric)
- a. to the ductus deferns (umbilical artery)
- internal pudental a. (internal iliac)
- inf. vesicular a. (internal iliac)
- middle rectal a. (internal iliac)
blood supply of the testis?
and what do they supply
- testicular a. (testis)
- cremasteric a. (tunica of the testes)
- branch of the pudental a. (scrotum)
innervation of the testis?
celiac plxus
scrotal n.
genital branch of genito femoral n.
the appendix of the testis is the remenance of?
mullerian duct
the appendix of the epididymis is the remenance of?
mesenphros
innervation of the epididymis?
celiac plexus
blood supply of the epididymis?
branch of the testicular a.
covering of the testis and epididymis from (deep to superficial)
and explain roughly each one
- tunica viganlis (serous sheath, remenant of processous viginalis testis)
- internal spermatic fascia ()
- cremasteric fascia (fibers of the cremaster covering the ISF)
- external spermatic fascia
- dartos fascia (subcutaneous tissue of the scrotum, no fat, consist of conn. tissue and smooth m.)
tell me all about the ductus deferens
- continuation of the duct of epididymis
- apulla of the ductusdeferns is a dilation of end of the ductus deferens
- opens into ejaculatory duct, located int he prostatic urethra
blood supply of the ductus deferens?
a. to the ductus deferens
innervation of the ductus deferens?
inferior hypogastic nerve plexus
where does the spermatic cord extend to?
from the deep inguinal ring trough the superficial inguinal ring, (the upper posterior part of the testis)
what are the coverings of the spermatic cord?
- external spermatic fascia
- cremasteric fascia
- internal spermatic fascia
contents of the spermatic cord
- testicular artery
- a. of the ductus deferens
- cremasteric a.
- genital branch of the genito femoral nerve
- testicular sympathetic plexuses
- pampiniform plexus
- lymphatic vessels
- ductus deferens
