male GU Flashcards
corpora cavernosa and corpora spongiosum in the penis
- two corpora cavernosa which run along the sides of the spongiosum: Both erectile tissue
- Corpus spongiosum (with urethra running through it) ends in the glans
what is the corona of the penis?
-Corona is widened area at base of glans
visceral tunica in the testes- what does it encase?
Visceral tunica vaginalis encases the anterio/lateral testes, posteriorly the epididymis is NOT covered by the visceral tunica.
The testes are encased in how many layers of tissue that are derived from the layers of the abdominal wall?
four
dartos muscle and fascia: what does it do?
Contracts the scrotal skin to decrease the surface area thereby preserving heat in the body
(Not the same thing and the Cremasteric muscle which is in charge of the testes)
4 layers of the spermatic cord
- Peritoneum: the tunica vaginalis
- Transversalis fascia: Internal spermatic fascia
- Internal abdominal oblique muscles adds the cremasteric muscle
- External abdominal oblique muscle adds the external spermatic fascia
what is tested in the “turn your head and cough” rule?
external ring for inguinal hernia
what two processes must be intact for an erection to occur? (extensive explanation of bloodflow process)
- blood flow must increase to corpora cavernosa via pudendal artery,
- venous outflow resistance must increase as result of blood trapping via venoocclusive mechanism,
…Increase in blood inflow without outflow allows higher intracavernosal volume and pressure which results in increased penile length and rigidity
lymph nodes: Penile and scrotal skin drain into the ____ ______
inguinal nodes
lymph nodes: The testes considered “____ _____” drain into…
abdominal lymph system.
three things to check the prepuce/foreskin for?
Phimosis- can’t retract foreskin
Paraphimosis- cannot reduce foreskin once retracted
Smegma- normal whitish material- normal
what do you check the skin at the base of the penis for ? (3)
excoriations, nits or lice
checking the urethra: how do you do this? what are you looking for?
compress glans to open urethra to look for
discharge. May need to “milk” urethra
2 part inspection of the scrotum
Skin- looking for rashes, epidermoid cysts, skin cancer rare
Scrotal contour- swelling, lumps or veins
palpation of the scrotum: part 1
Palpate each testis and epididymis between what fingers? where is the epididymis and what should it feel like?
- Palpate each testis and epididymis between thumb and first two fingers. Epididymis is superior, posterior of the testicle, should feel nodular and cordlike
