kanalikulær

Kanlikulær is an adjective used in anatomy and histology to describe structures related to canaliculi, the small channels or ducts found within tissues. The term derives from Latin canaliculus, meaning a small channel, and is employed across several languages to name microscopic or narrow tubular passages lined by epithelial or endothelial cells.

In the liver, biliary canaliculi are minuscule channels formed between adjacent hepatocytes that collect bile secreted by these cells and drain it toward the bile duct system. Their integrity and organization are essential for bile formation and excretion. In the tear drainage system, lacrimal canaliculi connect the lacrimal puncta to the lacrimal sac and are part of the nasolacrimal drainage pathway that channels tears away from the eye.

In dental tissue, canaliculi within dentin are slender channels that extend from the dental pulp toward the dentin surface. They contain processes of odontoblasts and play a role in nutrient diffusion and sensory signaling within dentin.

The term can also be applied to canalicular structures in other organs, always indicating a small, narrow channel. Clinically, canalicular involvement may be referenced in conditions such as canaliculitis, an infection of the lacrimal canaliculi, or in discussions of ductal versus canalicular architecture. Overall, kanalikulær denotes features characterized by small, delicate channels critical to tissue fluid movement and drainage.
