UTERINE WALLS

PERIMETRIUM Outermost wall Formed of connective tissue

MYOMETRIUM Thickest layer Composed of bundles of smooth muscle fibers Outer longitudinal Inner vascular

ENDOMETRIUM Consist of epithelium and lamina propria containing simple tubular glands

EPITHELIUM

GLANDS OF UTERUS

PROLIFERATIVE PHASE Simple columnar epithelium Glands are straight tubular with narrow lumen

SECRETORY PHASE Glands become highly coiled Endometrium reaches its maximum thickness

SECRETORY PHASE

MENSTRUAL PHASE Shedding of endometrium Rupturing of blood vessels Endometrium is reduced to thin layer of connective tissue

UTERINE TUBES The uterine tubes are paired tubes that extend bilaterally from the uterus toward the ovaries. Also commonly referred to as Fallopian tubes.

WALLS OF UTERINE TUBE WALLS OF UTERINE TUBE Mucosa Muscularis Serosa

MUCOSA Simple columnar epithelium with two types of cells Ciliated and peg cells Lamina propria Formed by loose connective tissue

Ciliated cells are most numerous in the infundibulum and ampulla. The wave of cilia is directed towards the uterus.

Non-ciliated peg cells are secretory cells that produce the fluid that provides nutritive material for the ova.

MUSCULARIS organized into an inner thick circular layer and outer thin longitudinal layer.

SEROSA is the outermost layer of the uterine tube and is composed of mesothelium and a thin layer of connective tissue.

INACTIVE MAMMARY GLAND Sparse glandular tissue Consist of tubules having the appearance of ducts
