Yep. Bones are wet. There, that's something you now know. You might not like it, but when we're alive our bones are stuffed with gooey marrow and riddled with vessels. So, it seems a bit odd, then, that the English idiom “bone dry” has become so well established.
The skin contains 64% water, muscles and kidneys are 79%, and even the bones are watery: 31%.
Although bones are very hard organs, they also have a dense network of blood vessels inside them where the bone marrow is located as well as on the outside that is covered by the periosteum. This is why bone fractures often cause serious bleeding.
In summary the wet turkey bones are prepared by cleaning and are kept moist until testing. Dry bones on the other hand, are cleaned, boiled and allowed to dry for a period of two weeks.
Exposure of large portions of the skeleton usually does not occur until four to six months after death. Bleaching and exfoliation of bone--the beginning stages of destruction of the skeletal elements--begins at about nine months' exposure.
A bone left lying outside will eventually disintegrate in a process called “weathering,” which is one component of taphonomy. Forensic scientists use a six-stage weathering scale, with “0” meaning not weathered at all, and “5” meaning that the bone is crumbling into dust and splinters.
If a body is buried in a coffin very deep the ground it could take 50 years for all the tissue to de-compose, and hundreds of years for the bones to fully decay.
As you get older, those minerals can start to leech out of your bones, leaving them brittle, fragile, and easily breakable, a condition known as osteoporosis. Women over 50 are especially at risk for osteoporosis because during menopause they lose estrogen, which helps to keep bones strong.
(b) A dried bone will become brittle because of the loss of collagen.
Overview of Osteonecrosis
The bones of the human body are made up of living cells that need a blood supply to stay healthy. In osteonecrosis, blood flow to part of a bone is disrupted. This results in death of bone tissue, and the bone can eventually break down and the joint will collapse.
Spongy bone is found mostly at the ends of bones and contains red marrow. Bone marrow is found in the center of most bones and has many blood vessels.
The hardest bone in the human body is the jawbone. The human skeleton renews once in every three months. The human body consists of over 600 muscles.
The thigh bone is called a femur and not only is it the strongest bone in the body, it is also the longest. Because the femur is so strong, it takes a large force to break or fracture it – usually a car accident or a fall from high up. To fix it properly requires an operation.
Abstract. Bone represents a porous tissue containing a fluid phase, a solid matrix, and cells.
Inside Your Bones
The inner layer, known as trabecular or cancellous bone, features a light network of connective tissue. This cancellous bone resembles a honeycomb, with the spaces filled with fluid, bone marrow cells that make blood, and some fat cells.
Bones then go through their own decomposition process, called diagenesis, which can last years to decades. Bone has two components: protein (collagen) and a mineral, hydroxyapatite. Protein degrades first, which leaves the remaining skeletal material susceptible to cracking and flaking.
Soaking bones in water will soften the tissue and allow you to scrape it off. There are also lots of microorganisms in the water which will eat away at the tissue. So, you end up with very clean bones. This method is especially good at getting rid of tissue in tiny crevices in skulls.
Soaking the bone in acid dissolves part of the bone material, leaving behind a tough, but rubbery, substance. Made mostly of special protein fibers, it makes up about one-third of the bone's total weight.
Muscle and bone conditions in older age
osteomalacia – the bones become soft, due to problems with the metabolism of vitamin D. osteoporosis – the bones lose mass and become brittle. Fractures are more likely.
A: It varies. If you follow your doctor's instructions and allow for adequate rest and recovery time, your bone should heal within three to six months. More extensive injuries, especially those that involve a joint, may require two years or more for optimal recovery.
What's happening. With age, bones tend to shrink in size and density, weakening them and making them more susceptible to fracture. You might even become a bit shorter. Muscles generally lose strength, endurance and flexibility — factors that can affect your coordination, stability and balance.
Clavicle. The clavicle, more commonly called the “collarbone”, is one of the most frequently fractured bones in the body. In fact, it's the most common site for a fracture in children. Clavicle fractures can happen to infants during birth as they pass through the birth canal.
By 50 years in, your tissues will have liquefied and disappeared, leaving behind mummified skin and tendons. Eventually these too will disintegrate, and after 80 years in that coffin, your bones will crack as the soft collagen inside them deteriorates, leaving nothing but the brittle mineral frame behind.
Ebn e Arabi says: coccyx is that stable part of human body which remains with human self forever.
However, on average, a body buried within a typical coffin usually starts to break down within a year, but takes up to a decade to fully decompose, leaving only the skeleton, Daniel Wescott, director of the Forensic Anthropology Center at Texas State University, told Live Science.
