What does canaliculi mean?
Canaliculi is the plural of canaliculus, an anatomical term for a very small channel or passage. Its best-known use refers to the microscopic channels that run through bone. These passages connect the lacunae, or small spaces, where osteocytes are housed, and allow the cells' processes to communicate, exchange nutrients, and receive signals. The term can also describe minute channels in other tissues, notably the bile canaliculi between liver cells, which collect bile and direct it toward larger ducts. Canaliculi is principally a technical term used in medicine and biological research rather than general conversation. Its Latin-derived plural ending is retained in English, so canaliculi occurs alongside the singular canaliculus. The word is useful when precision matters: it identifies a small anatomical conduit rather than a large vessel or duct.
nounSmall, narrow channels or passages within an anatomical structure, especially the microscopic channels in bone that connect lacunae and allow osteocyte processes to communicate.
- Anatomical small channels, especially the microscopic passages in bone that connect lacunae and contain osteocyte processes.
- Minute channels in other organs or tissues, such as the bile canaliculi formed between liver cells.
"Tiny canaliculi connect the lacunae in the bone matrix, allowing osteocytes to exchange nutrients and signals."
"Osteocyte processes extend through bone canaliculi to connect with neighboring cells in adjacent lacunae."
"Bile canaliculi form a branching network between hepatocytes and convey newly produced bile toward the larger biliary passages."
Canaliculi is the standard plural of canaliculus and is often more common in anatomical usage than the singular.
"Each osteocyte extends slender processes into neighboring canaliculi."
The tiny canaliculi in bone form a living communication network, letting bone cells exchange nutrients and signals through an otherwise solid matrix.

Where does canaliculi come from?
Canaliculi comes through Latin anatomical usage from Latin canaliculus, a diminutive of canalis, meaning “small canal” or “channel.” The larger Latin family also produced English words such as canal and channel through Old French. The Latin plural ending was retained in the English anatomical term, giving canaliculi alongside the singular canaliculus.
