Answer 5

1. NO–> increases cGMP –> SM relaxation and vasodilation

2. NE–> increases intracell Ca–> SM contraction/ vasoconstriction

Question 6

what is emission

Answer 6

when sperm moves from testes to prostatic urethra to mix with seminal fluid

Answer 12

Ligament of the ovary

Question 13

contains ovarian vessels

Answer 13

Suspensory ligament of the ovaries (infundibulopelvic ligament)

Question 14

contains uterine vessels

Answer 14

Cardinal ligament

Question 15

left ovary/testis drain to what vein

Answer 20

left gonadal vein–> left renal vein

Question 21

right ovary/ testis drain to what vein

Answer 21

right gonadal vein–> IVC

Question 22

what side is varicocele more common on and why

Answer 22

left–> venous pressure is higher due to the 90 degree angle the left gonadal vein connects to the left renal vein with
