(Phys.org) —The primary cilium plays the role of conductor, and antenna, to many kinds of cells. In photoreceptors, the cilium has been morphed into an expansive pigment-infused photon sieve, while in olfactory cells it ...
A study has shown for the first time that starfish use primitive eyes at the tip of their arms to visually navigate their environment. Research headed by Dr. Anders Garm at the Marine Biological Section of the University ...

A cilium (Latin for eyelash; the plural is cilia) is an organelle found in eukaryotic cells. Cilia are slender protuberances that project from the much larger cell body.
There are two types of cilia: motile cilia and non-motile, or primary cilia, which typically serve as sensory organelles. In eukaryotes, cilia and flagella together make up a group of organelles known as undulipodia. Eukaryotic cilia are structurally identical to Eukaryotic flagella, although distinctions are sometimes made according to function and/or length.
