Answer 5

external and internal iliac nodes

BUT more internal iliac!

Question 6

where does the lower vagina lymph drain?

Answer 6

superficial inguinal

Question 7

what organ(s) drain into the lumbar nodes in the male?

Answer 7

testes

Question 8

where does the lymph from the prostate, seminal vesicles, ductus deferens drain?

Answer 8

internal iliac nodes

Question 9

what is the pelvic pain line?

above the PPL? below the PPL?

Answer 9

PPL = corresponds to the lower limit of the peritoneum

Below:
pain travels by parasympathetic by inferior hypogastric plexus
pain is referred to S2-S4

above:
pain travels by the sympathetic by the inferior hypogastric plexus
pain is referred to the T10-L2

Question 10

Answer 10

deep dorsal vein (penis +clit)

internal pudendal vein (post. labial + scrotal)

external pudendal vein (anterior scrotum + labia majora)

Question 11

Answer 11

deep inguinal nodes

Question 12

Answer 12

Compression of the pudendal nerve

burning sensation or numbness

Question 13

failure of the dorsal nerve?

bulbospongiosus muscle?

Answer 13

dorsal: loss of sensation at head of penis and clit
muscle: failure to ejaculate

Question 14

bloos supply of the prostate?

Answer 14

inferior vesicle A.

Question 15

prostatic cancer metastasis

Answer 15

cancer cells can spread by the internal venous plexus since it is connected to the prostatic plexus

may have back pain due to spinal damage

Question 16

dilation of the helicine arteries and allow filling of blood

parasympathetic

priapism = prolonged blood pooling

emission phase?

expulsion phase?

Answer 21

emission:
sympathetic innervation
inferior hypogastric plexus

expulsion:
pudendal nerve
muscle contractions from bulbo + ischio
