Ciliaepitelial

Ciliaepitelial refers to epithelial tissue that is characterized by the presence of cilia, which are hair-like appendages extending from the apical surface of the cells. These cilia are motile, meaning they can beat in a coordinated fashion, creating a current that moves substances along the epithelial surface. The structure of cilia is complex, consisting of a basal body anchoring them to the cell and a central core of microtubules arranged in a characteristic 9+2 pattern.

The function of ciliaepitelial tissue is primarily related to the movement of fluids or particles. In the respiratory tract, for example, cilia beat upwards to propel mucus and trapped debris away from the lungs, contributing to airway clearance. In the fallopian tubes, cilia help to move the egg from the ovary towards the uterus. They are also found in parts of the central nervous system, such as the ventricles of the brain, where they circulate cerebrospinal fluid.

The cells that form ciliaepitelial tissue are typically columnar or pseudostratified columnar in shape, although cuboidal cells can also be ciliated. The presence and density of cilia can vary depending on the specific location and function of the tissue. Disorders affecting cilia function, such as primary ciliary dyskinesia, can lead to a range of health problems due to impaired clearance mechanisms.
