Perguntas frequentes

What is the fallopian tube epithelium?
The fallopian tube epithelium is a simple columnar epithelium that lines the inner surface of the fallopian tube. It is composed of two main cell types: ciliated cells, which bear motile cilia that beat toward the uterus, and peg cells (secretory cells), which produce tubal fluid that supports gamete transport and fertilization.
Where is the fallopian tube epithelium located?
The fallopian tube epithelium is located along the entire luminal surface of the fallopian tube, from the intramural segment within the uterine wall to the fimbriae at the ovarian end. It is the innermost layer of the tube, facing the tubal lumen, and is supported by the lamina propria and muscularis beneath it.
What is the function of the fallopian tube epithelium?
The fallopian tube epithelium functions to transport the ovum from the ovary to the uterus through ciliary beating and smooth muscle contractions. The secretory cells produce tubal fluid rich in growth factors, nutrients, and signaling molecules that support sperm capacitation, fertilization, and early embryo development within the tube.
What conditions may affect the fallopian tube epithelium?
The fallopian tube epithelium may be associated with salpingitis caused by sexually transmitted infections such as chlamydia and gonorrhea, which can cause epithelial damage, deciliation, and adhesion formation. Endometriosis, hydrosalpinx, and ectopic pregnancy may also involve significant changes in the tubal epithelium.
How is the fallopian tube epithelium examined?
The fallopian tube epithelium is examined histologically in sections of tubal tissue obtained during surgery such as salpingectomy. Pathologists evaluate ciliated and secretory cell ratios, epithelial height, and inflammatory or dysplastic changes. The SEE-FIM (Sectioning and Extensively Examining the FIMbriated end) protocol is used when evaluating for occult carcinoma.
