    GlossaryPrimary Cilia

    small, hair-like cellular structures that sense environmental signals

    Primary cilia are small, hair-like structures that extend from the surface of most human cells. They act as sensory antennas, detecting signals from the cell's environment and playing crucial roles in cell communication and signaling pathways. These structures are essential for various biological processes, including development and tissue maintenance, and their dysfunction can lead to a range of diseases known as ciliopathies.
