Slide DMS176 [Fallopian tube, monkey , H&E]. Your slide will show a cross-section of either the ampulla or isthmus of the oviduct. The wall consists of highly folded mucosa, a mucularis (inner circular, outer longitudinal layers of smooth muscle and a serosal layer. Look for the mesosalpinx. Study the mucosa at high magnification. The epithelial layer varies between simple columnar and pseudocolumnar and is composed mostly of ciliated cells with some interspersed non-ciliated secretory (peg) cells. The lamina propria consists of loose fibroelastic connective tissue.

XS of Uterine Tube: 1. Epithelium, containing both secretory & ciliated cells; 2. Lamina Propria; 3. Muscularis layers, l.s. & c.s.; 4. Serosa
