If the ovum is not fertilized and therefore does not become implanted in the uterus, the corpus luteum soon degenerates to form a corpus albicans, which eventually disappears. (Figs. 344, 345) Remnants of the embryonic mesonephros remain associated with the ovary throughout life, as the epoophoron, paroophoron, and the stalked hydatid of Morgagni. So far as is known, these are functionless. Seros

The criterion of full lactation which is adopted here is discussed below (p. 444). During the first lactation the gland undergoes an apparently irreversible change; it may enlarge to over 20 cm. in thickness (mean 16-1 cm., range 8-24 cm.) and although it involutes after weaning (or death) of the calf it does not revert to the former i Stock Photohttps://www.alamy.com/licenses-and-pricing/?v=1https://www.alamy.com/discovery-reports-discovery-ship-scientific-expeditions-ocean-antarctica-falkland-islands-4io-discovery-reports-lactating-females-with-one-corpus-albicans-in-the-ovaries-will-be-in-their-first-lactation-and-in-the-material-there-are-seven-such-records-the-criterion-of-full-lactation-which-is-adopted-here-is-discussed-below-p-444-during-the-first-lactation-the-gland-undergoes-an-apparently-irreversible-change-it-may-enlarge-to-over-20-cm-in-thickness-mean-16-1-cm-range-8-24-cm-and-although-it-involutes-after-weaning-or-death-of-the-calf-it-does-not-revert-to-the-former-i-image231420720.htmlRMRCE3DM–.
