MEDICAL PHYSIOLOGY

Detailed explanation-1: -The fimbriae of the uterine tube, also known as fimbriae tubae, are small, fingerlike projections connected to the end of the fallopian tubes, through which eggs move from the ovaries to the uterus.

Detailed explanation-2: -The Fallopian tubes have small hair-like projections called cilia on the cells of the lining. These tubal cilia are essential to the movement of the egg through the tube into the uterus. If the tubal cilia are damaged by infection, the egg may not get ‘pushed along’ normally but may stay in the tube.

Detailed explanation-3: -Microscopic anatomy Histologically, the uterine tubes are composed of 3 layers-the mucosa, muscularis, and serosa. The 3 different cell types within the mucosa of the uterine tubes include the columnar ciliated epithelial cells (25%), secretory cells (60%), and narrow peg cells (< 10%).

Detailed explanation-4: -This layer also contains cilia. Cilia are hair-like structures. They move to propel the ovulated egg from the ovary towards the uterus. They also help distribute tubal fluid throughout the tube.
