calcium
, the mineral that gives bone its strength and hardness. When bone develops, calcium crystals form in the gaps and bond to the flexible collagen like mortar amid the bricks.
What gives bones flexibility and tensile strength?
The organic components of bone help to give it additional strength and flexibility.
Collagen
, a ropelike, fibrous protein, is the major organic component of bone. Like rope, collagen has significant mechanical strength under tension. Therefore, collagen provides tensile strength to the bones.
What gives bones some flexibility?
Collagen
is a protein that provides a soft framework, and calcium phosphate is a mineral that adds strength and hardens the framework. This combination of collagen and calcium makes bone strong and flexible enough to withstand stress.
Which substances in the bones allow flexibility and hardness?
The hardness of bone is due to crystalized inorganic mineral salts as calcium phosphate. the flexibility and tensile strength of bone are due to
organic molecules such as collagen fibers
.
What fibers provide flexibility?
Elastic fibers
are made of the protein elastin; this fiber can stretch to one and one half of its length and return to its original size and shape. Elastic fibers provide flexibility to the tissues.
Which component of bones gives them their hardness?
Bones are made up of a framework of a protein called collagen ,
with a mineral called calcium phosphate
that makes the framework hard and strong. Bones store calcium and release some into the bloodstream when it’s needed by other parts of the body.
What ingredient in bone matrix lends it flexibility?
The inorganic matrix gives the rigidity and hardness to bone and is composed of a combination of calcium and phosphorus salts called hydroxyapatite. The organic
collagen fibers
give a bone its tensile strength and resistance to stress.
Which Fibre gives ligaments and tendons their flexibility?
Collagen fiber
is made from fibrous protein subunits linked together to form a long and straight fiber. Collagen fibers, while flexible, have great tensile strength, resist stretching, and give ligaments and tendons their characteristic resilience and strength.
What does collagen provide as a component of bone quizlet?
Collagen fibers
help bone resist twisting, pulling, or stretching forces
. Collagen fibers help the bone resist compression.
What do bones produce?
Bone marrow produces
red blood cells, platelets, and white blood cells
. Lymphocytes are produced in the marrow, and play an important part in the body’s immune system.
Where does the hardness of bone come from?
The hardness and rigidity of bone is due to the presence of
mineral salt in the osteoid matrix
, which is a crystalline complex of calcium and phosphate (hydroxyapatite). Calcified bone contains about 25% organic matrix (2-5% of which are cells), 5% water and 70% inorganic mineral (hydroxyapatite).
Which most helps to give bone some flexibility and prevents it from being brittle?
The bone is made up mostly of
calcium
. This mineral along with the framework made up of collagen helps to make bones very strong, like concrete. … Overall the material and engineering of the bone allow for it to be very rigid, yet flexible, making them hard to break and good at their function of support and protection.
What provides bone with hard and non pliable properties?
Complete answer: – Bones have a hard and non-pliable ground substance
rich in calcium salts and collagen fibers
which give the bone its strength.
What produces the elastic and collagen fibers?
Fibroblasts
synthesize most components of connective tissue, including collagen, elastic fibers and proteoglycans.
What is elastic cartilage?
Elastic cartilage is
a structural cartilaginous tissue for non-load-bearing body parts
, such as ears, nose, and epiglottis (Hutmacher et al., 2003).
Are bones elastic?
Elasticity. Bone mineral is a ceramic material and
exhibits normal Hookean elastic behaviour
, i.e. a linear stress-strain relationship. In contrast, collagen is a polymer that exhibits a J-shaped stress-strain curve.
