Bones form the skeletal frame of the body and are made up of calcium. These comprise of various joints, tendons, ligaments, muscles which together give the frame a fleshy and shapely appearance and also enable various movement activities. But the main frame is made up of bones. These bones too have various specialties and types. Compact bone is an important part of the skeletal system and has intricate structures of collagen fibers in which calcium phosphate and calcium carbonate are integrated to form the You do not have access to view this node.
Our body constitute of bone tissue which is classified into compact You do not have access to view this node or spongy You do not have access to view this node. This classification is based on the way cells as well as the matrix is organized. Compact You do not have access to view this node is also termed as cortical bone and is the traditional, heavy, hard, white and unyielding type of You do not have access to view this node. It is very dense and our 75% body weight is due to compact You do not have access to view this node density.
Compact bone is found wrapped around the cancellous bone to protect it and is made up of osteons. These osteons are cells composed of delicate layers of lammelae which protect the nerves and blood of the inner core compact bone. On death osteons transform into lammelae and produces barrier between osteon cells located inside the compact bone matrix. Due to this the strength and density of compact bones builds up. These osteons look like the tree rings and differ in appearance in various animals. Hence the gender, age, or type of specie can be identified on checking the make up of osteon remnants. Haversian canal which preserves the nerves and blood source is placed in the inner core of the compact bone and is protected by a very hard external shell.
The two canals: Osteons and Haversian canals assist the compact bones is disposal of waste and mineral deposits which enable solid growth and strength. The overall bone skeletal of human body is composed of cortical bone and cancellous bone tissue. Compact bone’s presence is more prominent in the form of long limbs of legs and arms. The skull bones, which are one of the most vital parts of our brain system, are made up of compact You do not have access to view this node with cancellous bones lying inside. These give us the capacity to defend trauma and support and balance our weight. It’s simply impossible to function for a body, in the absence of compact You do not have access to view this node.
Bones, especially compact bone tissue need regular intake of calcium in diet along with other minerals and hormones. Vitamins like D and K are too very vital for their development. Deficiency of any of these substances can produce alteration in the bone structure and hence can affect function of bones. During the aging process, some amount of demineralization occurs naturally, but too much calcium loss makes bones thin and weak due to which they become vulnerable to fracture. This is the most common condition of bones affecting our health. Some other diseases related to compact bone are osteoporosis, infection like osteomyelitis and birth defects affecting bone and muscle function and structure (congenital musculoskeletal).
