Also, it includes the femur (the longest bone in the body). They are longer in shape than their width. Long Bones that support weight and Facilitate Movement Moreover, they provide a large area for the attachment of a muscle.
In addition, they have a somewhat flat surface that acts as a protective shield. Besides, they protect internal organs like the brain, pelvic organs, and heart. Furthermore, the skull, thoracic cage, and the pelvis all are flat bones. We refer to them as flat bones because they are flat in shape. Let us discuss the Bones in Human Body in greater detail – 1. There are five types of skeletons and bones in human body as follows – Types of Skeletons in Human Body In addition, different types of bones have a different structure according to their function.
Besides, the bones in human body are classified into various categories.Īlso, the human skeleton has a number of functions such as supporting weight and protecting the organs. On average there are 206 bones in the human body. Most noteworthy, with time the bones merge into each other and that’s why at birth the infants have around 270 bones and when he grew up (At age 21) the number of bones decreases to 206 bones. Furthermore, calcium hardens the framework and the combination of collagen and calcium makes bones strong and flexible to endure stress. The bones are a solid structure made up of calcium phosphate and collagen. The intervening cancellous tissue is called the diploë, and this, in certain regions of the skull, becomes absorbed so as to leave spaces filled with air between the two tables.1.9 Solved Question for You Bones of Human Body In an adult, most red blood cells are formed in flat bones. These bones are composed of two thin layers of compact bone enclosing between them a variable quantity of cancellous bone, which is the location of red bone marrow. In the cranial bones, the layers of compact tissue are familiarly known as the tables of the skull the outer one is thick and tough the inner is thin, dense, and brittle, and hence is termed the vitreous table. The flat bones are: the occipital, parietal, frontal, nasal, lacrimal, vomer, scapula, os coxæ, sternum, and ribs. These bones are expanded into broad, flat plates, as in the cranium, the ilium, sternum, rib cage, the sacrum and the scapula.
