A microscopic examination of a connective tissue reveals a hard and non-pliable ground substance that is rich in calcium salts and collagen fibres. Which of the following statements is INCORRECT regarding the tissue described above?
Options
- AIts cells are called osteocytes and are present in spaces called lacunae.
- BIt interacts with skeletal muscles attached to them to bring about movements.
- CIt is classified as a dense regular connective tissue.
- DThe bone marrow in some of them is the site of production of blood cells.
Correct answer
C. It is classified as a dense regular connective tissue.
Step-by-step solution
The tissue described has a hard and non-pliable ground substance rich in calcium salts and collagen fibres, which is the characteristic feature of bone. Bones are classified as specialised connective tissues, not dense regular connective tissues. Dense regular connective tissues include tendons and ligaments. The other statements are correct for bone: bone cells (osteocytes) are present in spaces called lacunae; bones interact with skeletal muscles to bring about movements; and bone marrow in some bones is the site
