Answer 2

The Substance that Provides Bone Elasticity

The substance that provides elasticity to bones is collagen. Collagen is a protein that forms the structural framework of bones and gives them their flexibility and strength. It is the most abundant protein in the human body and plays a crucial role in maintaining the integrity and resilience of bones.

Collagen fibers are arranged in a matrix that provides a scaffold for the deposition of minerals, such as calcium and phosphate, which give bones their hardness and rigidity. This combination of collagen and minerals allows bones to withstand stress and absorb impact without breaking.

Collagen is produced by specialized cells called osteoblasts, which are responsible for bone formation. These cells secrete collagen into the extracellular matrix, where it forms a network of fibers that provide the necessary elasticity to bones.

It is important to note that while collagen provides elasticity to bones, other factors such as mineralization and bone density also contribute to bone strength and overall bone health.
