Question

what is lacuna??
plz tell​

Answer 1

Answer:

A lacuna is a gap in a manuscript, inscription, text, painting, or musical work. A manuscript, text, or section suffering from gaps is said to be "lacunose" or "lacunulose". Some books intentionally add lacunas to be filled in by the owner, often as a game or to encourage children to create their own stories

Answer 2

$\blue{\bold{\underline{\underline{Answer:}}}}$

Bone is usually formed in layers or lamellae which contain collagen fibers in a nearly parallel array, and a small proportion of proteoglycans and other substances.

Function of lacuna:-

Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae. Small channels (canaliculi) radiate from the lacunae to the osteonic (haversian) canal to provide passageways through the hard matrix.
