GENERAL KNOWLEDGE

Detailed explanation-1: -Osteoblasts are bone-forming cell, osteoclasts resorb or break down bone, and osteocytes are mature bone cells.

Detailed explanation-2: -Bone cells are the cells that make up bone tissue. Bone is a highly specialized connective tissue with three main functions; to protect the internal organs, to create a rigid frame for muscular movement, and to store minerals such as calcium and phosphorous.

Detailed explanation-3: -The two different types of osseous tissue are compact bone tissue (also called hard or cortical bone) tissue and spongy bone tissue (also called cancellous or trabecular bone).

Detailed explanation-4: -Bone is a mineralized connective tissue that exhibits four types of cells: osteoblasts, bone lining cells, osteocytes, and osteoclasts [1, 2]. Bone exerts important functions in the body, such as locomotion, support and protection of soft tissues, calcium and phosphate storage, and harboring of bone marrow [3, 4].
