Bones are often thought of as static structures which only offer structural support. However, they truly function as an organ. Like other organs, bones are valuable and have many functions.
Classically, bone has been considered as a structural organ that develops through the actions of specialized cells, particularly chondrocytes and osteoblasts.
The bones of your skeleton are a living organ. Bones are constantly being remodeled with old bone being resorbed and new bone being formed. It takes about 10 years for all the bone in your body to be renewed. That is why paying attention to bone health is important in adults and not just in growing children.
Specifically, an organ is a collection of tissues that carry out certain functions in the body. But are bones organs? Yes they are! They are composed of both minerals and cells and they have SEVERAL very important functions in the body.
The four principal types of bones are long, short, flat and irregular. Bones that are longer than they are wide are called long bones. They consist of a long shaft with two bulky ends or extremities. They are primarily compact bone but may have a large amount of spongy bone at the ends or extremities.
The bones of the human skeleton are classified by their shape: long bones, short bones, flat bones, sutural bones, sesamoid bones, and irregular bones (Figure 1). Figure 1. Shown are different types of bones: flat, irregular, long, short, and sesamoid.
Bone is made of protein, collagen, and minerals, especially calcium. Collagen provides a framework for the incorporation of mineral, mainly calcium phosphate into the collagen framework. The mineral makes bone hard and strong while the collagen provides flexibility so that the bone can resist breaking.
And they'd be right, of course: these are all internal organs of the body, also known as the viscera. What many people don't realize, though, is that the skin, bones, and even your muscles are also on that list. An organ is simply a collection of tissues that work together to perform bodily functions.
A whole skeletal muscle is considered an organ of the muscular system. Each organ or muscle consists of skeletal muscle tissue, connective tissue, nerve tissue, and blood or vascular tissue. Skeletal muscles vary considerably in size, shape, and arrangement of fibers.
What makes up the integumentary system? Your integumentary system is an organ that consists of a few main structures: skin, nails, hair and glands, along with the nerves and blood vessels that support them.
The main misconception about bones then, is that they are made up of dead tissue. This is not true, they have cells, nerves, blood vessels and pain receptors.
Bones provide a rigid framework, known as the skeleton, that support and protect the soft organs of the body. The skeleton supports the body against the pull of gravity. The large bones of the lower limbs support the trunk when standing.
You'll be surprised as to how much you could lose and still live. You can still have a fairly normal life without one of your lungs, a kidney, your spleen, appendix, gall bladder, adenoids, tonsils, plus some of your lymph nodes, the fibula bones from each leg and six of your ribs.
Answer and Explanation: The skull or bones are not organs.
Bone is living tissue that makes up the body's skeleton. There are 3 types of bone tissue: Compact tissue.
The heart is an organ about the size of your fist that pumps blood through your body. It is made up of multiple layers of tissue. Your heart is at the center of your circulatory system.
The skin is the body's largest organ.
Organs are defined as the collection of tissues that are mainly specialised for their own different purposes. Muscle, on the other hand, is a type of tissue. Heart can actually be referred to as a muscular organ.
Bone is made up of compact tissue (the hard, outer layer) and cancellous tissue (the spongy, inner layer that contains red marrow).
At the most basic level, the femur is classified as a bone in the skeletal system rather than an organ. However, it is sometimes classified as an organ as well because it is composed of several different tissue types and performs more functions than simply structural support.
Bone marrow fat (BMF) is located in the bone marrow cavity and accounts for 70% of adult bone marrow volume. It also accounts for approximately 10% of total fat in healthy adults above the age of 25 years (1, 2).
However, all vertebrates, including mammals rely on tiny concentrations of trace metal in our bones to control their formation, growth and repair. Wolverine's skeleton is made out of the fictional alloy adamantium, whereas the trace metals found in human bones include copper, calcium, zinc and strontium.
Bones cannot be bent due to their rigid and inelastic nature. They can break and result in fracture.
Flat bones are made up of a layer of spongy bone between two thin layers of compact bone. They have a flat shape, not rounded. Examples include the skull and rib bones.
