Question

Spaces present in matrix of bone in which bone cells [osteocyte] are present called as :

• A. Periosteum
• B. Bone marrow cavity
• C. Lamellae
• D. Lacuna

Answer 1

The correct option is D Lacuna

Bones have a hard and non-pliable ground substance rich in calcium salts and collagen fibres which give bone its strength . It is the main tissue that provides structural frame to the body. Bones support and protect softer tissues and organs. The bone cells (osteocytes) are present in the spaces called lacunae.
Limb bones, such as the long bones of the legs, serve weight-bearing functions. They also interact with skeletal muscles attached to them to bring about movements.

So, the correct answer is- lacunae.
