Cilliated Epithelium
Cilliated Epithelium : Structure. This epithelium consists of cuboidal or columnar cells that bear cilia on their free surfaces. A cilium is fine, vibratile cytoplasmic outgrowth that arises from a minute basal granule. Occurrence. Cuboidal ciliated epithelium lines certain parts of urinary tubules of the kidney and sperm ducts. Columnar ciliated epithelium lines the nasal passages, oviducts (fallopian tubes), terminal bronchioles and ventricles of the brain.
Function. This epithelium helps in the movement of mucus, urine, eggs, sperms and cerebrospinal fluid in a particular direction.
