It also helps in reducing the risks of osteoporosis. You can get it from various seafood sources such as fish and shellfish. Other good sources of magnesium include whole grains.
What are the two types of bone?
Two types of bone are found in the body—cortical and trabecular. Cortical bone is dense and compact. It forms the outer layer of the bone. Trabecular bone makes up the inner layer of the bone and has a spongy, honeycomb-like structure. The bone bank account. Women, men, and osteoporosis. Osteoporosis prevention.
When do bones become larger?
Think of bone as a bank account where you “deposit” and “withdraw” bone tissue. During childhood and the teenage years, new bone is added to the skeleton faster than old bone is removed. As a result, bones become larger, heavier, and denser. For most people, bone formation continues at a faster pace than removal until bone mass peaks during the third decade of life.
How can bone loss be prevented?
For many people, this bone loss can be prevented by continuing to get calcium, vitamin D, and exercise and by avoiding tobacco and excessive alcohol use. Osteoporosis develops when bone removal occurs too quickly, replacement occurs too slowly, or both.
What is the best way to understand osteoporosis?
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 ...
Why is prevention important for osteoporosis?
Prevention is important because although there are treatments for osteoporosis, a cure has not yet been found. A comprehensive program that can help prevent osteoporosis includes: A balanced diet rich in calcium and vitamin D. Weight-bearing exercise. A healthy lifestyle with no smoking or excessive alcohol intake.
Why do women have thinner bones than men?
This is because women generally have smaller, thinner bones than men have and because women can lose bone tissue rapidly in the first 4 to 8 years after menopause because of the sharp decline in production of the hormone estrogen.
Does estrogen affect bone?
Produced by the ovaries, estrogen has been shown to have a protective effect on bone. Women usually go through menopause between age 45 and 55. After menopause, bone loss in women greatly exceeds that in men. However, by age 65, women and men tend to lose bone tissue at the same rate.
What is bone made of?
Bone is a composite of proteins such as collagen and minerals such as calcium. Together these materials give bone a unique combination of strength and elasticity. Encyclopædia Britannica, Inc. See all videos for this article.
How strong is bone?
Compact (cortical) bone specimens have been found to have tensile strength in the range of 700–1,400 kg per square cm ( 10,000–20,000 pounds per square inch) and compressive strengths in the range of 1,400–2,100 kg per square cm (20,000–30,000 pounds per square inch). These values are of the same general order as for aluminum or mild steel, but bone has an advantage over such materials in that it is considerably lighter. The great strength of bone exists principally along its long axis and is roughly parallel both to the collagen fibre axis and to the long axis of the mineral crystals.
What are the properties of bone crystals?
The mineral crystals are responsible for hardness, rigidity, and the great compressive strength of bone, but they share with other crystalline materials a great weakness in tension, arising from the tendency for stress to concentrate about defects and for these defects to propagate. On the other hand, the collagen fibrils of bone possess high elasticity, little compressive strength , and considerable intrinsic tensile strength . The tensile strength of bone depends, however, not on collagen alone but on the intimate association of mineral with collagen, which confers on bone many of the general properties exhibited by two-phase materials such as fibre glass and bamboo. In such materials the dispersion of a rigid but brittle material in a matrix of quite different elasticity prevents the propagation of stress failure through the brittle material and therefore allows a closer approach to the theoretical limiting strength of single crystals.
How much elasticity does a bone have?
Estimates of modulus of elasticity of bone samples are of the order of 420 to 700 kg per square cm (6,000 to 10,000 pounds per square inch), a value much less than steel, for example, indicating the much greater elasticity of bone. Perfect elasticity exists with loads up to 30 to 40 percent of breaking strength; above this, “creep,” or gradual deformation, occurs, presumably along natural defects within the bony structure. The modulus of elasticity in bone is strikingly dependent upon the rate at which loads are applied, bones being stiffer during rapid deformation than during slow; this behaviour suggests an element of viscous flow during deformation.
What percentage of bone is made up of cells?
Depending upon species, age, and type of bone, bone cells represent up to 15 percent of the volume of bone; in mature bone in most higher animals, they usually represent only up to 5 percent. The nonliving intercellular material of bone consists of an organic component called collagen (a fibrous protein arranged in long strands or bundles similar ...
What are the major components of intercellular composites?
The major minerals of the intercellular composite are calcium and phosphate. When first deposited, mineral is crystallographically amorphous, but with maturation it becomes typical of the apatite minerals, the major component being hydroxyapatite.
What happens to the mineral-collagen ratio in bone?
As might be anticipated from consideration of the two-phase composition of bone, variation in the mineral-collagen ratio leads to changes in physical properties: less mineral tends ultimately to greater flexibility and more mineral to increased brittleness.
What are the functions of bone?
Bone provides shape and support for the body, as well as protection for some organs. Bone also serves as a storage site for minerals and provides the medium—marrow—for the development and storage of blood cells.
Why are bones important?
Because of the complexities of a bone's function, from providing strength and support for the body, to serving as a site for development and storage of blood cells, there are many disorders and diseases that can affect bone.
What is the soft tissue at the ends of bones called?
The smooth tissue at the ends of bones, which is covered with another type of tissue called cartilage. Cartilage is the specialized, gristly connective tissue that is present in adults. It is also the tissue from which most bones develop in children. The tough, thin outer membrane covering the bones is called the periosteum.
What is the tissue that makes up the body's skeleton?

The sponge-like tissue inside bones. Subchondral tissue. The smooth tissue at the ends of bones, which is covered with another type ...
What is the outer membrane of the bone called?
The tough, thin outer membrane covering the bones is called the periosteum. Beneath the hard outer shell of the periosteum are tunnels and canals through which blood and lymphatic vessels run to carry nourishment for the bone. Muscles, ligaments, and tendons may attach to the periosteum.
How many bones are there in the human body?
Bones are classified by their shape—as long, short, flat, and irregular. Primarily, they are referred to as long or short. There are 206 bones in the human skeleton, not including teeth and sesamoid bones (small bones found within cartilage): 80 axial bones.
