Bones play a tremendous role in the body and can affect routine functions such as appetite and a person’s health.
Scientists once referred to bones as a ‘dead organ’. But much to their surprise, bones are an important addition to the body. There is a vast amount of communication between bones and other organs within the body on a daily basis.
Bones require an abundance of energy as they constantly remodel their current structure. This procedure begins with a cell known as an osteoblast, which creates new bones, while a different cell, called an osteoclast, destroys past bones. Hormones also serve a vital role in the remodeling process. They regulate fuel sources that are needed for bone formation.
These amazing organs have abundant functions in the human body. Due to these many functions, bones may also be categorized as glands. Glands are tissues in the body that release hormones. Both bones and glands release hormones.
A mouse demonstration performed by Stravroula Kousteni, a physiologist at Colombia University Center, concluded that bones release the hormone Lipocalin (LCN2) into the bloodstream to impede infections. While in the bloodstream, it also travels to the brain where it gloms onto a hunger-controlling cell, telling the brain to stop eating.
Researchers have hypothesized that LCN2 is mainly made up of fat cells. However, it turns out that in mice, bones produce up to 10 times as much LCN2 as fat cells do. After a meal, their bones release enough LCN2 to boost blood levels of the hormone to triple from what it had been before the meal. Kousteni also concluded that appetite control is ‘a new role for the brain’.
Bones are an important factor in the body, yet are rarely recognized for the amazing things they are capable of, besides their vital role of holding our bodies together. There are so many other functions of bones that scientists haven’t discovered yet, some may be hidden while others are probably not.
