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 ...

A coronavirus infection can mow down the forests of hairlike cilia that coat our airways, destroying a crucial barrier to keeping the virus from lodging deep in the lungs. Normally, those cilia move ...

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 ...

Many cells in our body have a single primary cilium, a micrometer-long, hair-like organelle protruding from the cell surface that transmits cellular signals. Cilia are important for regulating ...

IN ctenophores the tall columnar cells which bear the large cilia are about 100µ × 8–12µ, arranged in groups along the combs 1. The large size of the cells makes it possible to record intracellular ...
