Cilia and flagella are evolutionarily conserved, microtubule-based, hair-like organelles that protrude from the cell surface. They are the fundamental units of motion in cellular biology, and also ...

Cilia are ubiquitous on cells, playing a variety of roles, Dr. Nicastro explained. While non-motile cilia serve as sensors for chemical and mechanical signals, motile cilia rhythmically beat to propel ...

Now, in a recently published Journal of Cell Biology paper, scientists used a newer electron microscopy technique, called volume electron microscopy (vEM), to examine how primary cilia on developing ...

In many cells of the human body, hair-like protrusions known as cilia act as antennae, allowing cells to receive signals from their environment and other cells. As cells grow and divide, each cilium ...

New research has unraveled the mystery of how microscopic cilia coordinate to move and propel marine creatures through water. Cilia are tiny, hair-like protrusions found in many organisms, including ...

Nerve cells in the brain make elaborate connections and exchange lightning-quick messages that captivate scientists. But these cells also sport simpler, hairlike protrusions called cilia. Long ...

Human bodies have some built-in systems to care for themselves. The cells that line our lungs, nose, brain and reproductive system have cilia, which are tiny, hair-like structures designed to sweep ...

Like the hairs they resemble, cilia come in all lengths, from short to long. But unlike the hair on our heads, the length of sensory cilia on nerve cells in our noses is of far more than merely ...

Some see a finger. Others, a worm. Scientists often call it an antenna. This tiny structure, sticking out from the surface of most human cells, is known as the primary cilium. Though nearly every cell ...

The motile cilia that line the epithelial tissue of the airways are considered the first line of defense against pathogens that cause several respiratory diseases. The airway epithelium consists of ...
