Jun 16, 2022 · In anatomy, a lacuna is defined as the space housing the osteocytes in bones and chondrocytes in cartilage. Biology definition: ( histology) Lacuna is the small cavity containing an osteocyte in bone, or a chondrocyte in cartilage; ( botany) an air space in plant tissues; ( general) a small depression, empty space, or cavity.
In histology, a lacuna is a small space, containing an osteocyte in bone, [1] or chondrocyte in cartilage. Bone. The lacunae 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 osteocyte is located in a small cavity in the bone tissue called a lacuna (lacunae for plural). Osteocytes maintain the mineral concentration of the matrix via the secretion of enzymes. Like osteoblasts, osteocytes lack mitotic activity.

lacuna. a cavity or depression, for example, one of many small spaces between the lamellae of bones that is occupied by individual bone cells. Small canals (canaliculi) radiate from the lacunae and in these are small protoplasmic processes which connect with the osteoblasts in other lacunae. see HAVERSIAN CANAL.
May 21, 2024 · Each osteocyte is located in a space called a lacuna and is surrounded by bone tissue. Osteocytes maintain the mineral concentration of the matrix via the secretion of enzymes. Like osteoblasts, osteocytes lack mitotic activity.
The osteocytes are located inside spaces called lacunae (singular = lacuna), found at the borders of adjacent lamellae. As described earlier, canaliculi connect with the canaliculi of other lacunae and eventually with the central canal.
