The lacuna are situated between the lamellae, and consist of a number of oblong spaces. In an ordinary microscopic section, viewed by transmitted light, they appear as fusiform opaque spots. Each lacuna is occupied during life by a branched cell, termed an osteocyte, bone-cell or bone-corpuscle.
The largest of these recesses is called lacuna magna (or the sinus of Guérin, or Guérin's sinus), which is situated on the upper surface of the fossa navicularis. Located deeper within the lacunae are branching mucous tubules called the glands of Littre.
In male anatomy, the lacuna magna (also called Guérin's sinus) is the largest of several recesses in the roof of the navicular fossa of the male urethra. Structure
Bone canaliculi are microscopic canals between the lacunae of ossified bone.The radiating processes of the osteocytes (called filopodia) project into these canals. These cytoplasmic processes are joined together by gap junctions.

Aerenchyma in stem cross section of a typical wetland plant. Aerenchyma or aeriferous parenchyma [1] or lacunae, is a modification of the parenchyma to form a spongy tissue that creates spaces or air channels in the leaves, stems and roots of some plants, which allows exchange of gases between the shoot and the root.

Lacuna Island is a small island lying 15 km (8 nmi) east of Tula Point, the northern end of Renaud Island, in the Pitt Islands, Antarctica. It was mapped from air photos obtained by Hunting Aerosurveys Ltd , 1956–57, and was so named by the UK Antarctic Place-Names Committee because the island lies in a lacuna (a gap) in the vertical air photos.
Lacunarity, from the Latin lacuna, meaning "gap" or "lake", is a specialized term in geometry referring to a measure of how patterns, especially fractals, fill space, where patterns having more or larger gaps generally have higher lacunarity. Beyond being an intuitive measure of gappiness, lacunarity can quantify additional features of patterns ...
