GENERAL HISTOLOGY

Detailed explanation-1: -The small space in the matrix, containing an osteocyte in bone or chondrocyte in cartilage is called as Lacunae. The Lacunae are situated between the lamellae and consist of a number of oblong spaces. Each lacuna is occupied during life by a branched cell, termed an osteocyte, bone-cell or bone-corpuscle.

Detailed explanation-2: -The cartilage cells or chondrocytes are contained in cavities in the matrix, called cartilage lacunae; around these, the matrix is arranged in concentric lines as if it had been formed in successive portions around the cartilage cells.

Detailed explanation-3: -Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.

Detailed explanation-4: -The cells of cartilage, called chondrocytes, are isolated in small lacunae within the matrix.

Detailed explanation-5: -Lacunae – Function The primary function of lacuna in bone or cartilage is to provide housing to the cells it contains and keeps the enclosed cells alive and functional. In bones, lacunae encase osteocytes; in cartilage, lacunae enclose chondrocytes.
