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.
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 ...
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.

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. Osteocytes do not entirely fill up the canaliculi.

Since their formation in 1994, the group has had two name changes, being previously known as Sleep of Right and Ethereal , [ 1 ] and they have recorded nine studio albums, two extended plays, two live albums, two compilation albums, one video album, and sixteen singles and music videos.
The chondrocyte in cartilage matrix has rounded or polygonal structure. The exception occurs at tissue boundaries, for example the articular surfaces of joints, in which chondrocytes may be flattened or discoid. Intra-cellular features are characteristic of a synthetically active cell.
Domain coloring of the 128th partial sum of the lacunary function =.. In analysis, a lacunary function, also known as a lacunary series, is an analytic function that cannot be analytically continued anywhere outside the radius of convergence within which it is defined by a power series.
