7: Andrology Flashcards
Urinary bladder trigone
Formed by 2 ureteric orifices + internal urethral orifice
Where is the involuntary internal sphincter of the bladder?
Neck of the bladder
Primary component of the wall of the urinary bladder
Detrusor muscle
Fascia surrounding detrusor muscle
Vesical fascia
Prostate gland homologue in females
Paraurethral glands
Urethral glands
Secrete mucus directly into urethra
Where is the anorectal flexure?
At levator ani muscles
Ampulla of the rectum
Holds fecal mass until defecation
Pectinate line
Separates embryologically different regions of the anal canal
What does the ductus deferens start and end from?
Epididymis -> ductus deferens -> ejaculatory ducts
Straight tubule of testis
Transfers spermatozoa to rete testes
Rete testis
Sinusoidal space where spermatozoa enter efferent ductules of epididymis
Ventral and dorsal cylinder of the penile erectile tissue from proximal to distal
Ventral cylinder: bulb, corpus spongiosum, glans penis
Dorsal cylinder: crura, corpora cavernosa
What transmits the spongy urethra?
Corpus spongiosum
Prostatic ducts
Convey prostatic fluid from parenchyma of the gland to prostatic sinus
Seminal vesicles
Paired elongated structures between urinary bladder + rectum, secrete fluid that adds to semen
Ejaculatory ducts are a union of what two ducts?
Ductus deferens + ducts of the seminal vesicle
Where do the ejaculatory ducts start?
Just proximal to the prostatic urethra
Bulbourethral gland secretions
Mucus-like substance during sexual arousal
Deferentectomy
Vasectomy; ligation and/or excision of ductus deferens thru a small incision in the superior scrotum -> ejaculant is devoid of sperm
How to determine prostate enlargement and prostatic cancer?
Digital rectal exams
