Cilia

Cilia are short, hair-like structures found on the surface of most cells in humans and other animals. They play a vital role in cellular movement, providing motility to cells and organisms. Cilia are also important for mediating the movement of extracellular material, aiding in the transport of particles such as dust and bacteria across epithelial surfaces. These microscopic appendages also allow for the coordination of cell activities such as wound healing, cell division and secretion of hormones. In addition, cilia have been linked to human diseases, including chronic respiratory and respiratory illnesses, as well as certain types of cancer. By understanding cilia, researchers hope to reveal more about human health and disease.
