Instead, the lacunae and osteocytes are found in a lattice-like network of matrix spikes called trabeculae (singular = trabecula) (Figure 7). Figure 8. Paget’s Disease. Parts of the Skeletal System (Source: Britannica) The skeletal system is made up of bones and cartilage. These salt crystals form when calcium phosphate and calcium carbonate combine to create hydroxyapatite, which incorporates other inorganic salts like magnesium hydroxide, fluoride, and sulfate as it crystallizes, or calcifies, on the collagen fibers. Every long bone is capped with wide areas on each end which are called epiphyses. Muscles And Bones For Kids. About this Quiz. Inside the diaphysis is the medullary cavity, which is filled with yellow bone marrow in an adult. If the outer layer of a cranial bone fractures, the brain is still protected by the intact inner layer. Again.

Compact bone is dense so that it can withstand compressive forces, while spongy (cancellous) bone has open spaces and supports shifts in weight distribution. The diaphysis takes the brunt of the force a long bone must support, and is made up primarily of compact bone -- a dense, strong bone composed of minerals, including calcium, phosphorus and magnesium, as hard as many types of rock. Gross Anatomy of Bones. A hole is an opening or groove in the bone that allows blood vessels and nerves to enter the bone. Identify the structures of a long bone. 2 Distinguish between compact and spongy bone. The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. Long bones -- a subtype of bones -- are longer than they are wide. Although bone cells compose a small amount of the bone volume, they are crucial to the function of bones. In which of the labeled parts of the adult long bone would hematopoietic tissue be located? Here we explain the anatomy of bone and the function of each part. The metaphyses are also important for bone growth during childhood and adolescence. Get 1:1 … In the diaphysis, or shaft, of each long bone, the is a central hollow cavity, called the medullary cavity. This tissue gives bones their smooth, white, and solid appearance, and accounts for 80% of the total bone Each osteon is composed of concentric rings of calcified matrix called lamellae (singular = lamella). Wrong 0. For this reason the medullary cavity is also called the marrow cavity. Osteoblasts, which do not divide, synthesize and secrete the collagen matrix and calcium salts.

Long bones have a thick outside layer of compact bone and an inner medullary cavity containing bone marrow. The two layers of compact bone and the interior spongy bone work together to protect the internal organs. Between the ephiphysis cap and the long shaft of the diaphysis is a wide section of bone called the metaphysis. Osteoclasts are continually breaking down old bone while osteoblasts are continually forming new bone. The cell responsible for bone resorption, or breakdown, is the osteoclast. This quiz has tags. Each epiphysis meets the diaphysis at the metaphysis, the narrow area that contains the epiphyseal plate (growth plate), a layer of hyaline (transparent) cartilage in a growing bone.

The hollow region in the diaphysis is called the medullary cavity, which is filled with yellow marrow. Inside the diaphysis is the medullary cavity, which is filled with yellow bone marrow in an adult. A long bone has two parts: the diaphysis and the epiphysis. Development of bone The process by which bone is formed is called ossification and there are two types: intramembranous and endochondral ossification. The spaces of the trabeculated network provide balance to the dense and heavy compact bone by making bones lighter so that muscles can move them more easily. There are two types of connective tissues called tendons and ligaments that are also considered a part of the system. In addition, the spaces in some spongy bones contain red marrow, protected by the trabeculae, where hematopoiesis occurs. structure of a long bone Long bone: elongated bone consisting of a body (diaphysis) and two terminal parts (epiphyses), such as the leg and arm bones (femur, radius, phalanges and others). Quiz: Brain – Sagittal View. The outer surface of the bone is covered with a fibrous membrane called the periosteum (peri– = âaroundâ or âsurroundingâ). The hydroxyapatite crystals give bones their hardness and strength, while the collagen fibers give them flexibility so that they are not brittle. The differences between compact and spongy bone are best explored via their histology. Arms And Shoulders Bone Labeled Spongy bone is composed of trabeculae that contain the osteocytes.
