The organic material in bone is collagen.This is a protein which forms long, flexible fibres in the matrix surrounding the bone cells. It is estimated that collagen makes up 25% of the total ...


The skeleton is the inner framework of BONES that supports and gives shape to the human body. It also protects some of the soft organs of the body—for example, the skull surrounds the brain. Muscles and ligaments pull on the bones of the skeleton at JOINTS to make the body move.


Are your bones at risk? If you’re over age 50, the answer is probably yes! It’s a simple fact of aging that the older we get, the weaker our bones become. We think of bone as a strong, almost solid material. In reality, our bones are mostly made of collagen, which is a protein. Collagen creates ...


Collagen is a mineral in your bone and marrow that makes your bones flexible yet strong enough to withstand a blow. :) The organic material in bone is collagen. This is a protein which forms long ...


You won't be able to make a wish on a wishbone with the rubber chicken bone science experiment! In this experiment, you use vinegar to remove the calcium in chicken bones to make them rubbery. This is a simple project that illustrates what would happen to your own bones if the calcium in them is used more quickly than it is replaced.


Have you ever wondered what makes bones so strong? You may have been told to drink milk, since calcium, a mineral found in milk, is important to strong bones. The body uses calcium to form hydroxylapatite, which it then uses to make bones and teeth hard. But bones need more than hydroxylapatite to make them strong.


To understand osteoporosis, it is important to learn about bone. Made mostly of collagen, bone is living, growing tissue. 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.


Besides impairing cardiovascular and kidney function, Type 2 diabetes is known to be a risk factor for bone fractures – but exactly how diabetes makes bones more fragile has been unclear. New research in animal models by a team of scientists at UC San Francisco, UC Davis, and UC Berkeley suggests ...


Bone is made mostly of collagen and calcium. This combination works to make the bones strong and flexible at the same time, enabling them to be protective and rebound from stress fractures.


Bones are fastened to other bones by long, fibrous straps called ligaments (LIG-uh-mentz). Cartilage (KAR-tul-ij), a flexible, rubbery substance in our joints, supports bones and protects them where they rub against each other. How Do Bones Grow?
