(7) continue to extend into the upper portion of the endometrium (functionalis
layer) (1) and become prominent because of thicker walls.
The alterations in the surface columnar epithelium (4), uterine glands (5),
and lamina propria (6) characterize the functionalis layer (1) of the endometrium
during the secretory or luteal phase of the menstrual cycle. The basalis layer (2)
exhibits minimal changes. Below the basalis layer is the myometrium (3) with
smooth muscle bundles (10), sectioned in different planes, and blood vessels
(9).
