Bones are the main part of the skeleton of humans and vertebrates. Bone tissue is a type of connective tissue. Bone, together with joints, ligaments, muscles and tendons attached to it, forms the musculoskeletal system. Bone cells (osteocytes, osteoclasts) and intercellular spaces are composed of mineral substances. Bone is formed during embryonic development from connective tissue - mesenchyme. Primary bone is formed from the ossification of the internal cartilage skeleton (shoulder, thigh, etc.), secondary bone from subcutaneous layers (forehead, skull and other bones). Keywords: osteocytes, osteoclasts, bone, bone tissue, ligaments, osteoblast in bone, osteocytes in lacunae, osteoblast cell.
