Question

State whether the given statement is true or false:
Bones are elastic tissues.

Answer 1

Bone is the strongest connective tissue having a very less ground material. It is made up of calcium and phosphorus. Also, bone is a hard matrix consisting of specialized bone cells, known as osteocytes.

Complete answer:
Bones are not elastic as they are made up of hard connective tissues. Bones form the skeletal system of the body thus providing support to the body. The internal organs of the body are protected by bones. These are whitish in color and are chiefly composed of calcium phosphate and calcium carbonate. Within the lacunae, bone cells (also known as Osteocytes) are present. A large number of vascular tissues are also present in bones therefore they are said to be highly vascularized which aid their fast recovery from injuries.Bones often acts as a reservoir of calcium, and thus plays a major role in maintaining the levels of calcium within the blood. Bones are not made up of elastic tissues rather they comprise of hard tissues.

The given statement is false.

Note: Collagen fibers entrenched in hydroxyapatite (a mineralized ground substance) form the extracellular matrix of bone which is very rigid. Also, hydroxyapatite is a type of calcium phosphate. The remarkable properties of bone are constituted by both the organic and inorganic components of the matrix. Collagen present in the matrix provides strength to the bones so that they do not break easily while the mineral crystals provide support to the body to prevent them from bending.
