SE'RETIOX AND EXCRETION OF THE SEMEN.

The semen is secreted by the minute branches of the sper-
matic arteries, that deposit it into corresponding seminal
vessels, called tasa rfcta, which compose the greater part of
the body of the testicle. The semen is the proper stimulus
to these vessels, which are therefore stimulated to contract,
and, by a very slow motion, convey it into the vasa efferen-
tia, which terminate in the epididymis. The vas deferens
carries it through the inguinal ring into the pelvis, to be de-
posited in the vesicals seminales, where it excites a desire to
emit it.

The cells of the corpora cavernosa penis, the corpus spon-
giosum, and glims penis, are distended with blood by the ve-
nereal stimulus; hence the penis swells, and is inclined for
coition ; during which action, at the time of the ccstntm vene-
'reum. the vesieulae seminales contract, and the semen is
thrown, with an immense force, through the ejaculatory
ducts, opening into the urethra, where it is mixed with the
secretion fiom the prostate gland, which is expelled at the
s une moment, and passes with it along the urethra, to be
propelled by the contraction, of the ejaculatory muscles into
die cavity of the uterus.
