The anal columns are folds of mucosa that extend vertically down from the rectum

sperm is the:

d. Bulbourethral gland.
ANS: B
In men, the prostate gland secretes a thin milky alkaline fluid that enhances sperm
viability. The Cowper glands (also known as bulbourethral glands) secrete a clear,
viscid mucus. The median sulcus is a groove that divides the lobes of the prostate
gland and does not secrete fluid.
