| Description: | The surface of the endometrium is covered by a
columnar/pseudostratified columnar epithelium. Coiled glands extend
into the stroma (except in the caruncles). The secretory activity of
the glands (with secretory and ciliated cells) is under the influence
of estrogen and progesterone. The superficial layer of the endometrium
is called the functional zone (stratum functional is) and is lost
(partially or fully) after pregnancy or after estrus. A thin deeper
layer, the basal zone (stratum basalis), persists and is the source of
tissue regeneration. PK1475. Original mag. 10x. Masson trichrome.
